Abstract

A medical fluid infusing device (400) transmits an inputted acquisition request to a control box (500). In response to the acquisition request, the control box (500) acquires imaging order data from a RIS (100). The imaging order data is replied from the control box (500) to the medical fluid infusing device (400). The medical fluid infusing device (400) sets at least a part of imaging order data as at least a part of infusion condition data. Therefore, the work load of inputting the infusion condition data on the health worker can be lightened. However, since the imaging order data is essential for a CT scanner (200) and has been conventionally present, no novel data creation is needed. Consequently, a fluoroscopic imaging system (1000) in which at least a part of infusion condition data can be easily set in the medical fluid infusion device (400) can be provided.

 Technical field

 TECHNICAL FIELD [0001] The present invention relates to a fluoroscopic imaging system that includes a fluoroscopic imaging device, a chemical solution injection device, and an image browsing device, and captures and displays fluoroscopic image data from a subject into which a chemical solution is injected.

 Background art

 [0002] At present, CT (Computed Tomography) scanner, MR I (Magnetic Resonance Imaging) apparatus, PET (Positron Emission Tomography) apparatus, Ultrasonic diagnostic equipment, etc. In addition, there are CT angio devices, MRA (MR Angio) devices, and the like as medical devices that capture blood vessel images, which are fluoroscopic image data of subjects.

 [0003] When using a device such as that described above, a chemical solution such as a contrast medium or physiological saline may be injected into a subject, and a chemical solution injection device that automatically executes this injection has also been put into practical use. A general chemical solution injection device holds a chemical syringe filled with a chemical solution, and injects a chemical solution into a subject by press-fitting a biston member into the cylinder member.

 [0004] Although the fluoroscopic imaging device functions as a stand-alone, normally, a fluoroscopic imaging system including the fluoroscopic imaging device as a part is constructed. Such a fluoroscopic imaging system includes, for example, a medical chart management device, an imaging management device, a fluoroscopic imaging device, a data storage device, an image browsing device, and the like.

 [0005] The medical chart management device is generally called a HIS (Hospital Information System) or the like, and manages a so-called electronic medical chart. This electronic medical record is created for each subject.

[0006] For example, when fluoroscopic image data is captured from a subject, imaging order data is created by the medical chart management device based on the electronic medical record of the subject. This imaging order data is obtained for each imaging operation that captures fluoroscopic image data from a subject. Generated.

 [0007] More specifically, the imaging order data includes, for example, imaging work ID (Identity) which is unique identification information, identification information of the fluoroscopic imaging device, identification information of the subject, start and end of imaging It consists of date and time.

 [0008] Such imaging order data is supplied from the medical chart management apparatus to the imaging management apparatus. The imaging management apparatus is generally called a radiology information system (RIS) or the like, and manages imaging order data for imaging fluoroscopic image data from a subject.

 The fluoroscopic imaging device acquires imaging order data from the imaging management device and executes an imaging operation. In that case, the fluoroscopic imaging apparatus captures fluoroscopic image data from the subject in correspondence with the imaging order data. This fluoroscopic image data is provided with at least a part of the imaging order data by the fluoroscopic imaging device and output to the data storage device.

 [0010] This data storage device is generally called PACS (Picture Archive and Communication System) or the like, and stores fluoroscopic image data to which imaging order data is added.

 [001 1] An image browsing device commonly called a viewer is connected to the data storage device. For example, the image browsing apparatus reads the fluoroscopic image data using the imaging order data as a search key and displays the fluoroscopic image data.

 However, the imaging management apparatus normally manages a plurality of imaging order data. For this reason, it is necessary to selectively provide one to the fluoroscopic imaging device from a plurality of imaging order data managed by the imaging management device. Therefore, there are two types of imaging management devices called push type and pull type.

 [0013] The push-type imaging management device selects one from a plurality of managed imaging order data, for example, by manual operation of an operator. When the push type imaging management apparatus receives an imaging order data acquisition request from the fluoroscopic imaging apparatus, it returns one selected imaging order data.

[0014] The pull-type imaging management device includes a request for acquiring imaging order data from the fluoroscopic imaging device. Along with this, an order search key is transmitted. This order retrieval key is made up of, for example, an imaging work ID of imaging order data.

[0015] Therefore, the imaging management apparatus searches imaging order data with the order search key, and returns the searched imaging order data to the fluoroscopic imaging apparatus. This fluoroscopic imaging device

When one appropriate imaging order data is returned, fluoroscopic image data is imaged from the subject corresponding to the imaging order data.

On the other hand, when a plurality of imaging order data is retrieved and returned, the fluoroscopic imaging device selects one from the received plurality of imaging order data, for example, by an operator's manual operation.

[0017] When the imaging order data transmitted from the imaging management apparatus as described above is determined by the fluoroscopic imaging apparatus, this is notified to the imaging management apparatus. For this reason

Even in the pull-type imaging management apparatus, one imaging order data used for imaging fluoroscopic image data by the fluoroscopic imaging apparatus is specified.

There are various proposals for the fluoroscopic imaging system as described above (see, for example, Patent Documents 1 and 2).

The section display unit 4 3 5 displays a schematic image of a plurality of body sections stored in the image storage unit 4 3 2 in an arrangement corresponding to the human body.

 The segment input unit 4 36 receives an input operation for selecting one of the plurality of body segments displayed as images by the segment display unit 4 35 as an input operation for one injection condition data. The region display unit 4 37 displays and outputs a schematic image of at least one imaging region corresponding to the body segment selected by the segment input unit 4 36.

Then, from the imaging order data, body classification, imaging site, body weight, type of contrast medium, and the like are extracted as injection condition data, and operation condition data is set corresponding to the injection condition data.

 [0074] The history generating unit 4 2 6 of the chemical solution injection device 400 corresponds to a function of the computer unit 4 0 5 executing a predetermined process corresponding to the computer program, and the injection history in which the history of chemical solution injection is recorded Generate data.

 [0075] The injection history data generated in this way is, for example, text data such as an injection work ID that is identification information unique to each injection work, one of the horizontal axis and the vertical axis is elapsed time, and the other is injection. Consists of image data of a speed graph over time.

As shown in FIG. 5, the image browsing apparatus 600 has a computer unit 601, a display unit 602, a controller unit 603, a communication I / F 604, and the like.

 [0083] As shown in FIG. 1, the image browsing device 60 0 0 has a data reading unit 6 1 1, data display, as the computer unit 6 0 1 executes various processes corresponding to the computer program. Part 6 1 2.

[0084] The data reading unit 6 1 1 is configured so that, for example, the computer unit 6 0 1 corresponds to the computer program and the input data to the control unit 6 0 3 and the communication I / F 6 0 4 to PACS 3 0 Corresponds to the function for accessing 0, etc. The fluoroscopic image data and the injection history data associated with the image work ID are read from PACS 300.

 [0085] The data display unit 6 1 2 corresponds to a function for the computer unit 60 1 to display the received data of the communication I / F 60 4 on the display unit 60 2, and the read fluoroscopic image data And injection history data are displayed.

 [0086] Note that the RIS 100 computer program described above, for example, manages imaging order data for imaging fluoroscopic image data from a subject with unique identification information, and supports operator input operations. Select one of multiple imaging order data, and return one selected imaging order data in response to an acquisition request received from CT scanner 2 0 0 or control box 5 0 0 , Etc. are described as software for causing RIS 100 to execute.

 [0087] Further, the computer program of the CT scanner 200, for example, transmits an imaging order data acquisition request to the RIS 100 corresponding to the input operation of the operator, and is returned from the RIS 100. Receiving the imaging order data, controlling the operation of the fluoroscopic imaging unit 210 in response to the received imaging order data, and adding the imaging order data to the fluoroscopic image data captured by the fluoroscopic imaging unit 210. It is described as software for causing the imaging control unit 210 to execute the assignment, transmission of the fluoroscopic image data to which the imaging order data is assigned, to the PACS 300, and the like.

[0088] Further, the computer program of the chemical injection device 400, for example, causes the touch panel 40 03 to display and output a schematic image of a plurality of registered body sections corresponding to the human body shape, and to display the image. Accepting an input operation to the touch panel for selecting one of the plurality of selected body sections, and displaying and outputting a schematic image of at least one imaging region corresponding to the selected body section; Accepting an input operation to select an imaged part to be displayed, reading operation condition data corresponding to the selected imaged part, accepting an input operation for weight, Product names of multiple registered contrast agents Show To output, to accept an input operation for selecting one of the displayed contrast agent types, to read the bar concentration corresponding to the selected contrast agent type, and to read Adjusting the corresponding operating condition data according to the input weight and the read bar concentration, displaying and outputting the adjusted total injection volume, which is the adjusted operating condition data, and displaying the total injection volume displayed To accept manual operation to correct the data, adjust the total injection volume corresponding to the input data, operate the syringe drive mechanism 4 1 1 with the adjusted operating condition data, The operation icon such as "" is displayed and output on the touch panel 4 0 3, and when the operation icon is input, an acquisition request is sent to the control box 5 0 0. The operation condition data is set based on the injection condition data consisting of a part of the imaging order data returned from the control box 5 0 0, and the injection history data including the time chart corresponding to the chemical injection Is generated as software for causing the computer unit 400 to execute, such as generating the injection history data and transmitting the generated injection history data to the control pox 500.

 It should be noted that resources used for the computer program as described above are also registered in the chemical liquid injector 400. This resource includes, for example, a data file that associates a schematic image of multiple body segments of a human body with schematic images of a large number of imaging regions, and operating condition data of the syringe drive mechanism for each of the multiple imaging regions of the human body. Data files, data files of bar concentration for each product name of multiple contrast media, etc.

[0090] Further, the computer program of the control box 500, for example, receives injection history data from the chemical injection device 400, and when the injection history data is received, the imaging order data is received in RIS 100. Sending an acquisition request, receiving imaging order data returned from RIS 100, adding imaging work ID, which is individual identification information of imaging order data, to injection history data, and imaging work ID is Output the given injection history data to PACS 300, etc., etc. It is stated.

 [0091] Further, the computer program of PACS 300, for example, receives fluoroscopic image data provided with imaging order data from CT scanner 200 and stores it, and performs imaging work of imaging order data. It is described as software that allows PACS 300 to execute the process of receiving and storing injection history data with IDs from control box 500, etc.

 Then, the computer program of the image browsing apparatus 600 reads out the fluoroscopic image data associated with the imaging work ID and the injection history data from the PACS 300, for example, And the injection history data are described as software for causing the computer unit 6 0 1 to execute.

 In the configuration as described above, a method for imaging fluoroscopic image data from a subject using the fluoroscopic imaging system 100 of this embodiment will be described in order below. First, the operator registers the imaging order data in RIS 100.

 The imaging order data is composed of text data such as imaging work ID, identification information of the CT scanner 200, date and time of imaging start and end, and the like. This imaging order data is usually created based on the electronic medical record for each subject.

[0095] For this reason, identification information, body weight, and the like of the subject are also registered in the imaging order data. However, the imaging order data consists of various data necessary for imaging work with the CT scanner 200. For this reason, data that can specify the injection operation of the chemical injection device 400 is not included.

 [0096] When such an imaging order data is registered in RIS 100, when the imaging operation is executed, the operator manually operates RIS 100 to cope with the imaging operation. One imaging order data is selected.

On the other hand, in the field of imaging work, as shown in FIG. 3, a chemical liquid injector 400 is arranged in the vicinity of the fluoroscopic imaging unit 2 0 1 of the CT scanner 2 0 0. Then, a test solution (not shown) located in the fluoroscopic imaging unit 210 is connected to the chemical solution with an extension tube. The syringe 4 3 0 is connected, and this chemical solution syringe 4 3 0 is loaded into the injection execution head 4 1 0 of the chemical solution injection device 4 0 0.

[0098] Next, when the operator activates the chemical solution injection device 4 0 0 by an input operation of the operation panel 4 0 2 of the injection control unit 4 0 1 or the like, as shown in FIG. 7, the touch panel 4 0 3 A schematic image of multiple body sections is displayed at the top corresponding to the human body shape.

 [0099] Below that, an imaging region selection screen is displayed in a horizontally long rectangle. In the lower half of the touch panel 40 3, a horizontally long condition screen is displayed in which the injection rate of the chemical solution is the vertical axis and the injection time is the horizontal axis. In such a state, for example, the identification information of the chemical solution, the identification information of the imaging region, and the like are input to the operation panel 40 2 by the operator as a part of the injection condition data.

 [0100] Further, the operator presses one of the schematic images of the plurality of body sections displayed on the touch panel 40 3 with his / her finger. Then, as shown in FIG. 8, only the schematic image of the selected body segment is brightened and the other schematic images are darkened, and a schematic image of the scanner mechanism is displayed above the schematic image of the selected body segment. Is done.

 [0101] At the same time, schematic images of a plurality of imaging regions related to the selected body segment are read out below and displayed on the selection screen. Therefore, when an operator performs an input operation with one finger or the like, as shown in FIG. 9, only the selected schematic image is highlighted and the other schematic images are darkened.

 [0102] When the imaging region is selected as described above, in the chemical solution injector 400, the target graph corresponding to the imaging region as the injection condition data is read out by the computer unit 45, and the operating condition Set as data.

 [0103] However, when the body weight is input as injection condition data and the contrast medium type is input as injection condition data and the odo concentration is read out, the operating conditions correspond to the body weight and the chode concentration. Data is adjusted.

[0104] More specifically, in the drug solution injector 400, the target graph is registered as a variable pattern that changes the injection rate with time as the operating condition data for the injection of the contrast medium. However, the variable pattern satisfies a predetermined total injection amount. Is set to

 [0105] Then, the total injection amount of the contrast agent odor corresponding to the body weight of the subject is registered as "A (g / Kg)" based on the experimental results. Therefore, when the subject's weight is input as “B (Kg)”, the total injection amount of the bar in proportion to this weight is calculated as “A x B (g)”. Furthermore, when the contrast concentration of the contrast agent is read as “C (g / ml)”, the total injection amount of the contrast agent becomes “(A x B) / C (ml)” in inverse proportion to the concentration. Calculated.

 When the total injection amount is calculated in this way, as shown in FIG. 9, when the target graph is registered with a predetermined variable pattern, for example, it is surrounded by the waveform and the x / y axis. The target graph is displaced up and down so that the injection time does not change so that the area that corresponds to the total injection amount.

 Then, the target graph generated as described above is displayed as a target time graph on the condition screen of the touch panel 40 3. At this time, an operation icon “correction” is also displayed on the work screen. By inputting the operation icon, it is possible to manually correct the injection condition data and the target graph.

 [0108] In addition, an operation icon "determine" is also displayed on the work screen. When this is input, the target graph is fixed and the injection of the contrast medium is executed. In that case, in the chemical liquid injector 400, the operation of the syringe drive mechanism 4 11 is controlled in accordance with the set target graph, and the contrast medium is injected into the subject.

 [0109] However, in the fluoroscopic imaging system 100 according to the present embodiment, the injection condition data can be automatically set in addition to being manually set in the chemical injection device 400 as described above. it can. More specifically, as shown in FIG. 7, the chemical injection device 400 according to the present embodiment also displays an operation icon “automatic setting” on the initial screen of the injection operation.

[0110] Therefore, when the “automatic setting” operation icon is manually operated, an acquisition request is transmitted to the control box 500 as shown in FIG. This control box 500 forwards the acquisition request received from the chemical injection device 400 to RIS 100. [01 1 1] Then, this RIS 1 0 0 returns one imaging order data selected as described above to the control box 5 0 0. When receiving the imaging order data from the RIS 100, the control box 500 returns a part of the imaging order data to the drug solution injector 400 as at least a part of the injection condition data.

 [01 12] More specifically, as described above, the imaging order data includes the imaging work ID, the identification information of the CT scanner 200, the date and time of imaging start and end, the identification information of the subject, the weight of the subject, Consists of body classification or imaging region, product name of contrast medium, etc.

 [01 13] Therefore, the control box 5 0 0 extracts the identification information of the subject, the weight of the subject, the body classification or imaging part, the product name of the contrast agent, etc. from the acquired imaging order data, and this is the injection condition. It returns to the chemical injection device 400 as part of the data.

 [0114] In the fluoroscopic imaging system 100 according to the present embodiment, since it is used for injection history data to be described later, a part of the imaging order data that does not become injection condition data such as an injection operation ID is also used in the control box Sent from 5 0 0 to chemical injection device 4 0 0.

 [0115] In the chemical solution injection device 400, injection condition data including a part of the imaging order data returned from the control box 500 in response to the acquisition request is set. When the injection condition data is automatically set in this way, the target graph is read and adjusted accordingly.

 Then, as shown in FIG. 9, the adjusted target graph is displayed as a target time graph on the condition screen of the touch panel 4 03. In this state, when the operation icon “Determination” on the work screen is input, the target graph is confirmed and the contrast medium is injected.

 [0117] In that case, in the drug solution injector 400, the syringe drive mechanism 41 is controlled in accordance with the set target graph, and the contrast medium is injected into the subject.

[01 18] At this time, the elapsed time is measured in real time and the actual injection speed Therefore, the operation of the syringe drive mechanism 4 1 1 is feedback controlled so that the injection speed matches the target graph.

[01 19] Furthermore, a time-lapse graph consisting of the actual injection rate is generated in real time and displayed on the touch panel 4 0 3 together with the target graph as shown in FIG.

. When the injection work is completed, injection history data including a time-dependent graph of the actual injection speed is generated.

[0120] The injection history data generated in this way includes, for example, injection work IDs that are identification information unique to each injection work, actual injection start and end dates and times, chemical injection device 400 identification information, injection It consists of text data such as condition data, and image data of time-lapse graphs.

[0121] Further, when the injection operation is completed, the chemical injection device 400 also generates completion notification data to which at least the injection operation ID is given and the completion is notified. Therefore

The chemical injection device 400 that has completed the injection operation transmits completion notification data and imaging order data to the control box 500.

[0122] Then, the control box 50 0 transfers the completion notification data received from the chemical solution injector 400 to R I S 100. This R IS 100 is stored in a state in which the received completion notification data is related to the imaging order data by the injection work ID.

 In addition, the control box 5 0 0 transfers the injection history data received from the chemical solution injection device 4 0 0 to P A C S 3 0 0. This P A C S 3 0 0 stores the received injection history data in a state managed by the imaging work ID.

 [0124] In the normal operation, the imaging operation by the CT scanner 200 is started before and after the injection operation by the chemical injection device 400 is completed as described above. In this case, the operator inputs an operation to start imaging to the imaging control unit 2 10 of the CT scanner 2 200.

Then, the imaging control unit 2 1 0 of the CT scanner 2 0 0 transmits an imaging order data acquisition request to the RIS 1 1 0 0. Then, this RIS 1 0 0 is obtained by the CT scanner 2 0 0 Return ¹ (to be said.

 [0126] Therefore, in this CT scanner 200, the operation of the fluoroscopic imaging unit 201 is controlled in accordance with the imaging order data received by the imaging control unit 210, so that the imaging work of the fluoroscopic image data is executed. Is done.

 [0127] When fluoroscopic image data is captured from the subject by the fluoroscopic imaging unit 201, imaging order data is added to the fluoroscopic image data in the imaging control unit 210. Next, in the imaging control unit 210, the fluoroscopic image data to which the imaging order data is added is transmitted to the P A C S 300.

 [0128] The PACS 300 stores the received fluoroscopic image data in a state managed by the imaging work ID of the imaging order data. Then, when the operator browses the fluoroscopic image data, for example, the fluoroscopic image data is read from the PA 300 by manual operation of the image browsing device 600.

 In this case, for example, when the imaging work ID is input as a search key, the fluoroscopic image data of the imaging work ID is read from the PACS 300 and displayed on the display unit 602 of the image browsing apparatus 600. Is done. At this time, the injection history data is also read out from the PACS 300 by the imaging operation ID, and is displayed on the display unit 602 of the image browsing apparatus 600 as necessary.

 In the fluoroscopic imaging system 1000 according to the present embodiment, an acquisition request input to the chemical injection device 400 is transmitted to the control box 500 as described above. Then, in response to the acquisition request, the control box 500 acquires imaging order data from the RIS 100 or the C T scanner 200.

 A part of the imaging order data is transferred from the control box 500 to the chemical liquid injector 400 as at least a part of the injection condition data. In this chemical injection device 400, injection condition data consisting of imaging order data is set.

[0132] For this reason, it is possible to reduce the work load for the operator to input the injection condition data, and to prevent erroneous input of the injection condition data. Nevertheless, the imaging order data is traditionally indispensable for CT scanner 200. The Therefore, it is possible to automatically set at least part of the injection condition data without the need to create new data.

 In addition, in the fluoroscopic imaging system 100 according to the present embodiment, the injection history data is also stored in association with the fluoroscopic image data stored as described above. For this reason, for example, injection history data can also be confirmed when viewing fluoroscopic image data. Accordingly, an operator viewing the fluoroscopic image data can check how the chemical solution has been injected into the subject at the time of capturing the fluoroscopic image data.

 [01 34] In particular, as described above, the fluoroscopic image data and the injection history data are related by the imaging operation ID. The imaging operation ID is used as the imaging order data when the injection condition data is automatically set. Acquired at 4 0 0.

 In other words, the imaging order data acquired from the RIS 1 0 0 through the control box 5 0 0 to the chemical injection device 4 0 0 is used for automatic setting of injection condition data and generation of injection history data. Can be used for both.

 [0136] Further, in the fluoroscopic imaging system 100 according to the present embodiment, since the fluoroscopic image data captured by the CT scanner 20 00 is in a good state, the drug solution injector 400 is used as a contrast agent. Vary the injection rate. However, since the time-lapse graph of the injection rate is included in the injection history data, it is possible to confirm in detail how the contrast agent was injected.

 [01 37] In addition, even if there is doubt about the injection of contrast media, the injection history data can be confirmed together with the fluoroscopic image data, so that the injection history data can be used as evidence. .

 [0138] In particular, the various devices 100 to 600 of the fluoroscopic imaging system 100 according to the present embodiment mutually communicate various data in accordance with the rules of D ICOM. The communication data of D I C O M is difficult to falsify, so the evidence history of injection history data is high.

[0139] Furthermore, even when fluoroscopic image data is imaged again from the same subject, the previous injection history data can be referred to. For this reason, it is possible to easily input accurate injection condition data to the chemical liquid injector 400. [0140] In particular, even when fluoroscopic image data is captured again from a subject whose weight has changed due to the progression of a medical condition, by referring to the previous fluoroscopic image data and injection history data, Accurate injection condition data can be easily input to 400.

 [0141] Moreover, in the present embodiment, a time-course graph is included in the injection history data. Therefore, even complicated injection condition data that corrects the target graph for changing the injection speed can be easily input to the chemical solution injection device 400.

 Furthermore, in the fluoroscopic imaging system 100 according to the present embodiment, injection history data containing text data such as injection condition data is stored as P A C S 3 0 0. For this reason, for example, various statistical data related to chemical solution injection can be generated from a large number of accumulated injection history data.

 In particular, since the injection history data is stored together with the imaging order data, various statistical data related to the chemical injection can be generated together with the imaging conditions included in the imaging order data.

 [0144] In addition, the completion notification data of the injection work is stored in the RI ISO 100 from the chemical solution injector 400 through the control box 500. In this RIS 1 00, since the completion notification data is managed in association with the imaging order data, for example, the start time and end time of chemical injection from the RIS 1 0 0 to the CT scanner 2 0 0 together with the imaging order data, etc. Can also be notified.

 [0145] In this case, since the operator operating the CT scanner 200 can refer to the start time and end time of the chemical injection, the start time of image capturing should be adjusted according to that time. Can do.

 [0146] The present invention is not limited to the above-described embodiment, and various modifications are allowed without departing from the scope of the invention. For example, in the above embodiment, it is exemplified that the imaging order data acquired from R IS 100 is transferred to the chemical injection device 400 by the control box 500 as a part of the injection condition data.

However, the control box 5 0 0 transfers all of the imaging order data to the chemical injection device 4 0 0, and a part of the imaging order data received by the chemical injection device 4 0 0 May be selected as injection condition data.

 [0148] Further, in the above-described embodiment, it is exemplified that RI 100 is a push type and that the control box 5 00 acquires appropriate imaging order data according to timing. And R I S 100 may be a pull type.

 [0149] In that case, the CT scanner 200 sends a request for acquiring imaging order data to the RISO 100 with at least one order search key. Then, the RI S 1 00 selects and returns one of the plurality of imaging order data corresponding to the acquisition request and the order search key received from the CT scanner 2 200.

 [0150] When receiving the acquisition request, the control box 5 0 0 transmits an acquisition request for imaging order data to the R 1 S 1 0 0. Then, the RI S 100 returns a piece of imaging order data selected corresponding to the acquisition request received from the control pod 50 00.

 [0151] Or, R 1 S 1 0 0 returns a plurality of imaging order data in response to the acquisition request received from the CT scanner 2 0 0. In this case, the CT scanner 200 receives an operation for selecting one of the returned plurality of imaging order data, and notifies the selected imaging order data to the RISO 100.

 [0152] Alternatively, the RI S 100 searches for a part from a plurality of imaging order data in response to the acquisition request and the order search key received from the CT scanner 20 00, and returns a response. The CT scanner 20 0 receives an operation for selecting one of the returned imaging order data, and notifies the selected imaging order data to the R 1 S 1 0 0.

 [0153] Therefore, when the acquisition request of the control box 5 0 0 force imaging order data is transferred to RIS 1 0 0, the RIS 1 0 0 responds to the acquisition request received from the control box 5 0 0 and the CT scanner 2 0 One imaging order data notified from 0 is returned.

[0154] By doing as described above, even if the RIS 1 0 0 is a pull type, the control box 5 0 0 acquires appropriate imaging order data and assigns an imaging work ID or the like to the injection history data. be able to. [0155] Further, in the above embodiment, the control box 50 0 is exemplified to acquire the imaging order data provided from the RIS 1 0 0 unconditionally. However, the control box 500 may send an imaging order data acquisition request to the RIS 10 00 together with at least one order search key.

 [0156] In this case, RIS 1 0 0 searches for a part from a plurality of imaging order data corresponding to the order search key received from control box 5 0 0, and performs CT on the part of the searched imaging order data. If there is one notified from Scanner 2 0 0, reply. As described above, appropriate imaging order data can be obtained more reliably than the control box 500 force.

 In the above-described case, for example, the chemical liquid injector 400 transmits at least part of the input injection condition data as an order search key to the control pox 500 with the acquisition request. The control pox 500 may transfer the received acquisition request and order search key to the RIS 100.

 [0158] Furthermore, in the above embodiment, the control pox 5 0 0 is exemplified to acquire the imaging order data from the R 1 S 1 0 0. RIS 1 0 0 and CT scanner 2 0 0 are connected via control pox 5 0 0 and control imaging order data transmitted from RIS 1 0 0 to CT scanner 2 0 0 Box 5 0 0 may be obtained.

 [0159] Also, the control box 5 0 0 is connected to the CT scanner 2 0 0 without being connected to the RIS 1 0 0, and the control box 5 0 0 from this CT scanner 2 0 0 to the imaging order data May be obtained.

 [0160] In that case, for example, the control box 5 0 0 transfers the acquisition request received from the chemical injection device 4 0 0 to the CT scanner 2 0 0 and receives it from the CT scanner 2 0 0 force control box 5 0 0 The imaging order data may be returned in response to the acquisition request.

[0161] Or CT scanner 2 0 0 Force Pull-type RIS 1 0 0 Accepts an operation to select one from multiple imaging order data, and the selected imaging order data is control box 5 0 It may be transferred to 0. [0162] Further, in the above embodiment, the injection history data generated by the chemical solution injector 400 is stored in the PACS 300 together with the fluoroscopic image data generated by the CT scanner 200.

 [0163] Even if the injection history data is transmitted from the chemical injection device 4 0 0 to the RIS 1 0 0 via the control box 5 0 0 and this injection history data is stored in the RIS 1 0 0 Good. In this case, in RI ISO 100, the imaging order data and the injection history data can be managed in association with the work ID or the like.

 [0164] Even in this case, the fluoroscopic image data registered in PACS 300 is also assigned the work ID of the imaging order data, so that the fluoroscopic image data and the injection history data can be associated with each other. .

 [0165] Further, in the above embodiment, it has been exemplified that all of the imaging order data is attached to the fluoroscopic image data and stored in the PACS 300. Only the imaging work ID of the imaging order data may be added to the fluoroscopic image data.

 [0166] Even in this case, the fluoroscopic image data and the injection history data can be associated with each other by the imaging work ID, and the imaging order data can be read out from the RISO 100 by the imaging work ID.

 [0167] In addition, only the imaging work ID of the imaging order data may be attached to the fluoroscopic image data, and the entire imaging order data may be added to the injection history data. The imaging order data may be assigned to the fluoroscopic image data, the injection history data, and the like. You may distribute and assign to.

 [0168] Furthermore, both the time-course graph and the target graph may be included in the injection history data. The entire display image of the touch panel 40 3 of the chemical solution injector 400 may be included in the injection history data.

 [0169] In the above embodiment, the injection history data is exemplified by the text data such as the injection work ID and the date and time, and the image data of the graph of the injection speed over time. However, the injection history data may consist only of the above text data.

[0170] In particular, in the above embodiment, the chemical solution injection device 400 is exemplified to vary the injection speed of the contrast agent and to include the time-lapse graph in the injection history data. But chemicals The injection device 400 may inject the contrast medium at a constant rate. In this case, it is not meaningful to generate and record a graph over time. Therefore, the injection rate should be included in the injection history data as text data.

[0171] In the above embodiment, only the injection condition data is set in the chemical solution injection device 400 is illustrated. However, the injection condition data may be notified from the chemical solution injection device 400 to the control pox 500, and the injection condition data may be notified from the control pox 50 00 to the RI ISO 100. In this case, the injection condition data can be notified from the RI S 100 to the CT scanner 200 along with the imaging order data.

 [0172] Therefore, since the operator operating the CT scanner 200 can refer to the injection condition data, the imaging operation can be adjusted in accordance with the injection condition data. In addition, it is not impossible to automatically adjust the imaging operation based on the injection condition data acquired by the imaging control unit 210 of the CT scanner 200.

 [0173] In the above embodiment, the injection history data is completed by the chemical injection device 400, and then transmitted to the control box 500. The chemical injection device 400 may distribute the injection history data to the control box 50 0 and transmit it, and the injection history data may be completed in the control box 500.

 [0174] More specifically, the chemical injection device 400 sends the injection condition data and start date and time to the control box 50 0 0 at the start of injection, and transmits the injection speed etc. in sequence during the injection process, and the injection ends. Also send the end date and time. In this case, the injection history data can be completed and output from the various data accumulated in the control box 500 from the start of injection to the end of injection.

[0175] Further, in the above embodiment, various devices 100 to 600 communicated with each other in the DICOM format, which is difficult to tamper with, thereby demonstrating high evidence capability such as injection history data. However, the chemical injection device 400 may generate injection history data in a data format that is difficult to tamper with, such as PDF (Portable Document Format). [0176] Similarly, the control box 500 is connected to the chemical injection device 400 from JPEG (Joint Photographic Cod i ng

 Injection history data received in Experts Group format may be converted to PDF format. Further, the chemical solution injector 400 and the control box 500 are connected to a so-called Internet, and an electronic signature may be acquired and added to the injection history data.

 [0177] Further, in the above embodiment, the injection condition data including the imaging order data acquired from the RIS 1 0 0 via the control box 5 0 0 by the chemical injection device 4 0 0 is the injection execution head. An example is shown on the touch panel 4 0 3 of the injection control unit 4 0 1 that is separate from 4 1 0.

 [0178] However, a small display panel (not shown) is arranged in parallel as a data display section in the injection execution head 4 10, and injection condition data including imaging order data is displayed there. Good. In this case, the injection condition data can be confirmed at the position of the injection execution head 4 10 which is placed in the vicinity of the subject and the chemical syringe 4 3 0 is attached.

 [0179] Further, in the above embodiment, it is exemplified that all of the injection condition data required by the chemical solution injection device 400 is extracted from the imaging order data acquired from the RIS 100. However, only part of the injection condition data required by the chemical liquid injector 400 may be acquired from the imaging order data, and the other part may be input to the chemical liquid injector 400.

 [0180] Further, injection condition data such as identification information of a subject is input to the chemical injection device 400, and the chemical injection device 400 receives the injection condition data and the injection condition data acquired from the imaging order data. A warning may be issued if the injection condition data to be verified does not match.

[0181] In this case, it is possible to prevent the injection condition data from being automatically set with incorrect imaging order data. Furthermore, if such a warning is displayed on the display panel of the injection execution head 4 10 described above, it is possible for the operator to recognize the warning quickly and reliably. [0182] Also, an RFID chip in which at least a part of the injection condition data is recorded is mounted on the chemical syringe 43, and an RFID reader that reads the injection condition data from the RFID chip is attached to the chemical injection device 400. The medical solution injection device 400 may collate the injection condition data of the RFID chip of the chemical syringe 43 30 with the injection condition data acquired from the imaging order data (not shown).

 [0183] In this case, it is possible to prevent the injection condition data from being automatically set with the wrong imaging order data and the chemical injection with the wrong chemical syringe 4 30 from being performed. Nevertheless, it is not necessary for the operator to input the injection condition data, and erroneous input can be prevented.

 [0184] Further, the product ID of the chemical solution is recorded on the RFID chip as described above, and at least the product ID of the chemical solution unsuitable for injection is set as the unsuitable ID for each subject and set in the imaging order data. The product ID input from the RFID chip and the inappropriate ID set in the imaging order data may be collated, and a warning may be issued if they match (not shown).

 [0185] More specifically, the prefilled type drug solution syringe is shipped in a state where the drug solution is filled. Therefore, an RFI D in which chemical data is registered as a data storage means is attached to a prefilled type chemical syringe (not shown).

 [0186] The chemical solution data includes, for example, various data such as volume, pressure resistance, cylinder inner diameter, piston stroke, identification data for each individual, and product ID, It consists of various data such as chemical classification, ingredients, viscosity, and expiration date.

[0187] The product ID of the chemical solution is registered due to the chemical classification of the chemical solution, the contained components, and the chemical structure, and is not related to the syringe capacity. For example, if there are products from Company A and Company B as contrast agents for cardiac use for CT, the type of chemical solution `` contrast agent for cardiac use for CT '' is common, but water-soluble or oily Or chemical classification such as ionic or nonionic, monomer type or dimer type If so, the product ID is different.

 [0188] Furthermore, even if the chemical type and chemical classification are the same, if the contained components are different, the product ID will be different, and even if the chemical type, chemical class and contained components are the same, for example, even one of the contained components If the chemical structure is different, the product ID is different.

 [0189] — On the other hand, if the same chemical solution is filled in the chemical syringes with the prefilled type with the capacity of “200 (ml)” and “500 (ml)”, the chemical syringe will depend on the volume. The product ID of the chemical solution is the same.

 [0190] On the other hand, in the imaging order data, the above-mentioned inappropriate ID, etc. are registered in addition to the subject ID for each subject, personal data such as gender and age, various data on diseases, and the like. In this state, when the chemical syringe is properly loaded in the injection execution head of the chemical injection device, the chemical data is acquired from the R FI D chip by the R F I D reader.

 [0191] Then, when the chemical liquid injector acquires the injection condition data from the imaging order data, the inappropriate ID set in the injection condition data is compared with the product ID set in the chemical liquid data.

 [0192] When the product ID and the inappropriate ID match, a warning message such as "This drug cannot be injected into this subject" is displayed on the touch panel and the syringe drive mechanism is disabled. Control the operation.

 [0193] For this reason, for example, if the type of chemical that is injected into the subject is appropriate for the type of CT contrast agent, but is inappropriate for injection due to the subject's personal reasons such as side effects, this is the case. The injection device can automatically detect and notify the operator. Therefore, the operator can quickly recognize itself and take measures such as changing the chemical solution.

[0194] In particular, the product ID is automatically acquired when the drug syringe is loaded into the injection execution head, and the inappropriate ID is automatically acquired when imaging order data is input as the injection condition data. For this reason, there is no need for dedicated work for acquisition and verification, and product IDs and inappropriate IDs can be verified easily and reliably. [0195] Similarly, the chemical component contained in the RFID chip of the chemical syringe is recorded as data, and the improper injection component is registered in the imaging order data as the inappropriate component, and the contained component and the inappropriate component are collated. It is also possible.

 [0196] Also, the chemical classification of the chemical solution is recorded on the RFID chip of the chemical syringe, and the chemical classification that is inappropriate for injection is registered as an inappropriate classification in the imaging order data, and the chemical classification and the inappropriate classification are collated. It is also possible.

 [01 97] In these cases, the propriety of injection into the subject can be managed for each component and chemical classification. For this reason, for example, it is possible to accurately predict whether or not a chemical solution is injected for the first time.

 [01 98] Furthermore, the syringe drive mechanism is operated until it is confirmed that the inappropriate ID or the like is not registered in the imaging order data, or if the inappropriate ID and the product ID do not match if registered. It can also be initially set to disabled. In this case, it is possible to reliably and automatically prevent inadequate chemicals from being injected into the subject.

 [01 99] As mentioned above, imaging order data is generally created from electronic medical records for each subject, and the electronic medical records show the product ID, ingredients, chemical classification, etc. of drugs with side effects. It can be registered as an inappropriate component or inappropriate classification. Therefore, imaging order data in which inappropriate IDs are registered as described above can be easily created.

 [0200] Further, as described above, when the chemical injection device 400 notifies a warning, the syringe drive mechanism 4111 may be controlled to be inoperable until the warning is released. In this case, it is possible to prevent the medicinal solution that becomes a warning target from being injected into the subject.

[0201] Furthermore, in the above-described embodiment, the chemical solution injection device 400 was exemplified to inject only the contrast medium into the subject by using one chemical solution syringe 40. However, the chemical solution injection device may inject a contrast medium, physiological saline, or the like into the subject as a chemical solution using a plurality of chemical solution syringes (not shown). In such a case, for example, injection condition data for sequentially injecting a contrast medium and physiological saline as a drug solution to a subject can be registered in the imaging order data. [0202] In the above embodiment, the CT scanner 200 is used as the fluoroscopic imaging device, and the chemical solution injector 400 injects the CT contrast agent as the chemical solution. However, the fluoroscopic imaging device is composed of an MR I, PET device, an ultrasonic diagnostic device, etc., and a medical solution injection device may inject a contrast medium therefor.

 [0203] Further, in the above embodiment, the CT scanner 200 and the chemical liquid injector 400 are individually operated as stand-alone units. The CT scanner 200 and the chemical injection device 400 may link various operations by data communication.

[0204] Also, in the above embodiment, for simplicity of explanation, it is illustrated that each part of the fluoroscopic imaging system 1000 is one. However, in large hospitals, each of multiple fluoroscopic imaging systems has one RIS 100, CT scanner 200, chemical injection device 400, and one control box 500. The ACS 300 and the image browsing device 600 may be shared (not shown). However, even in such a case, there may be a plurality of hardware connected in parallel (not shown), such as RIS 100, PACS 300, and image browsing apparatus 600.

 [0205] Further, in the above embodiment, it is exemplified that the fluoroscopic image data and the injection history data are stored by one PACS 300. However, the hardware for storing the fluoroscopic image data and the hardware for storing the injection history data may be formed separately and connected via a communication network.

 [0206] Also, in the above embodiment, RIS 100, CT scanner 200, P ACS 300, chemical injection device 400, control pox 500, and image viewing device 600 are formed separately and are connected by communication networks 701 to 706. Exemplified that they are connected.

[0207] However, the various devices 200 to 600 as described above may be integrally formed by various combinations. For example, the injection control unit 401 and the control box 500 of the chemical injection device 400 are integrally formed, the RIS 100 and the PACS 300 are integrally formed, the P ACS 300 and the image It is also possible that the browsing device 600 is integrally formed.

[0208] In addition, RI 100 and PACS 300 are integrally formed in the control box 500, the control box 500, the PACS 300, and the image viewing device 6

It is also possible that 00 is integrally formed.

[0209] Further, the imaging control unit 210, RIS 100, and control box 500 of the CT scanner 200 are integrally formed, and the imaging control unit 210, PACS 300, and the control pox 500 of the CT scanner 200 are integrated. It is also possible that the image viewing apparatus 600 is formed integrally with the image viewing apparatus 600.

 [0210] In addition, the image browsing device 600 and the PACS 300 are integrally formed, and the imaging control unit 2 of the control box 500 and the CT scanner 200 is added thereto.

It is also possible that 10 is integrally formed.

[0211] Furthermore, in the above-described embodiment, it is exemplified that each unit of various devices 100 to 600 is logically realized as various functions by operating the computer device corresponding to the computer program.

[0212] However, it is also possible to form each part as unique hardware. It is also possible to form a part as software and a part as hardware.

[0213] Needless to say, the various forms described above, unless the contents conflict.

Can be combined in various ways. Further, in the above-described embodiments and modifications, the structure of each part has been specifically described, but the structure and the like can be changed in various ways within a range that satisfies the functions of the present invention.
