Description

  The present invention relates to a radiographic image capturing system, and more particularly to a radiographic image capturing system using a portable radiographic image detection apparatus that performs wireless communication.

  In the field of medical diagnosis, a CR (Computed Radiography) system capable of handling radiographic images as digital data has been put into practical use. This CR system includes a reading device that reads radiation image data by scanning a phosphor plate built in the CR cassette with excitation light, and a control device (also called a console) that acquires the radiation image data read by the reading device. ) And are connected. Then, the radiographic technician can obtain the optimum radiographic image data by reading the CR cassette irradiated with radiation in the radiography room with a reading device and transmitting the obtained radiographic image data to the control device for display. Can be confirmed.

  In this CR system, generally, instruction information called imaging order information including patient information (patient name, age, etc.) and imaging information (imaging date, imaging region, imaging direction, etc.) is generated in advance. A workflow is used in which one imaging order information and one cassette ID, which is identification information of a CR cassette, are registered in association with each other (see, for example, Patent Document 1).

  On the other hand, in recent years, a digital radiological image detection apparatus has been used as a method for obtaining a radiographic image by irradiating a subject with radiation and detecting the radiation transmitted through the subject. As such a radiation image detection apparatus, there is a so-called FPD (Flat Panel Detector).

  As an example of an FPD, a plurality of detection elements are two-dimensionally arranged on a substrate, radiation that has passed through a subject is irradiated on a phosphor (scintillator), and visible light that emits light according to the amount of irradiated radiation is emitted. There is one that obtains a radiographic image by converting electric charge into a capacitor by a detection element and accumulating it in a capacitor and reading out the electric charge accumulated in the capacitor. Such an FPD has immediacy that a radiographic image can be obtained immediately after imaging.

  With such an FPD, even if a workflow such as that used in Patent Document 1 is used, efficient shooting cannot be performed. On the other hand, from the viewpoint of convenience of information use and speed of various processes, HIS (Hospital Information System) is a system that centrally manages patient diagnosis information and accounting information, and a system that manages radiographing order within radiology. RIS (Radiology Information System) has been introduced. In these, various radiographic image capturing apparatuses and control terminals of the image capturing apparatuses are connected to the RIS and the HIS via a network such as a LAN (Local Area Network) disposed in the hospital.

  Patent Document 2 discloses a radiographic imaging system in which a plurality of consoles (control terminals) and a plurality of FPDs having a communication function are connected to such a hospital network. In order to improve the efficiency of image confirmation by an operator such as a radiographer or doctor, the radiographic imaging system described in Patent Document 2 associates a console with an FPD in advance before imaging and associates in advance after imaging. The radiographic image acquired by FPD is transmitted to the console.

In Patent Document 3, a plurality of consoles and a plurality of FPDs are connected using a portable cassette type FPD (hereinafter referred to as a portable FPD) provided with a wireless communication unit and a wireless repeater disposed in a photographing room. A radiographic imaging system is disclosed. In the radiographic image capturing system described in Patent Literature 3, when capturing with the FPD, the operator ID that performed the capturing is associated with the radiographic image data. The photographer registers an operator ID when operating a console that displays an image obtained by radiography, and the FPD is radiation image data associated with an operator ID that matches the registered operator ID. Is sent to the console. In this way, even when the photographer repeatedly photographs while moving between multiple consoles, the radiographic image data obtained by radiography can be confirmed on the console currently used by the photographer. , Radiation imaging efficiency is improved.

  In the portable cassette type FPD, a plurality of images can be taken continuously. In the case of performing continuous imaging, in the case of performing imaging across a plurality of imaging rooms, the radiographic imaging system disclosed in Patent Document 2 needs to return to the console that was first associated with the radiographic imaging system. In general, the console is provided near the first shooting room, and is provided far from the moving shooting room. In such a case, the image data cannot be confirmed and associated with the photographing order unless the console is moved to a distant console.

  Further, in the radiographic imaging system disclosed in Patent Document 3, when imaging is performed across imaging rooms, the operator ID and console association are canceled and re-established at the console near the imaging room where the imaging was performed last. There has been a problem that a registration operation must be performed and an operation that is troublesome for the operator is required.

[Control flow]
Here, a control flow for registering the identification ID and the imaging order information in the console 7 based on the position information in the radiographic imaging system 1 will be described with reference to FIGS.

  FIG. 4 is an explanatory diagram of a control flow performed by the radiographic imaging system according to the present embodiment. First, in step S10 in FIG. 4, the management server 2 transmits imaging order information to the console 7. In step S11, shooting order information for shooting is selected and registered from shooting order information received by one console 7 (for example, console ID: C01).

  FIG. 5 is a diagram illustrating an example of the imaging order information list displayed on the display unit 77 of the console 7. As shown in FIG. 5, each imaging order information includes “patient ID” P2, “patient name” P3, “sex” P4, “age” P5 as patient information, and “clinical department” P6, “ It includes an imaging part “P7”, an “imaging direction” P8, and an “imaging stand” P9. Then, in the order in which the orders are received, “shooting order ID” P1 is automatically assigned to each shooting order information. Patient information and imaging information are not limited to those described above, and may include information such as the patient's date of birth, the number of medical examinations, and the radiation dose. Further, it is not necessary to include all these pieces of information, and information included in the shooting order information can be set as appropriate in accordance with the shooting purpose, shooting flow, and the like. These pieces of information are acquired from the HIS and RIS connected to the network N and stored in the database 21 of the management server 2. Then, by accessing the management server 2, the console 7 acquires photographing order information as shown in FIG.

  The radiologist can select imaging order information for imaging by operating the button in the h12 column. The imaging order information selected by pressing the enter button h13 after selection is registered and stored in the storage unit 70. In step S <b> 12, the radiologist selects the radiation image detection device 6 to be used for imaging from among the cassette IDs registered in the console 7 in advance.

  FIG. 6 is a diagram illustrating an example of a setting screen for associating the imaging order information displayed on the display unit 77 of the console 7 with the cassette ID. This figure is a screen displayed by depressing the enter button h13 in FIG. 5, and the shooting order information selected in step S11 is displayed in the display field h22 in FIG. The cassette ID registered in the console 7 (console ID: C01 in the figure) is displayed in the display column h21, and the cassette that performs imaging for each imaging order ID displayed in the display column h22. The ID can be selected by operating the operation button h25. In the example shown in the figure, the imaging orders with imaging order IDs 001 to 004 are associated with the radiation image detecting apparatus 6 with the cassette ID F01. The radiologist presses the decision button h23 to determine the association. Note that once this confirmation operation is performed, the imaging order information related to the confirmation operation cannot be associated with other cassette IDs.

  In step S <b> 13, the control unit 74 transmits the associated cassette ID and imaging order information as a unit to the management server 2.

  In step S <b> 14, the management server 2 registers the received cassette ID and imaging order information in association with each other and stores them in the storage device 21. The above is the flow for registering shooting order information.

  Next, a flow for registering the radiation image detection device 6 in the console ID based on the position information will be described. In step S <b> 21, the control unit 64 of the radiological image detection apparatus 6 acquires position information. The position information is acquired by identifying which imaging room 100 the radiological image detection apparatus 6 is located in (1) identification information such as the MAC address of the access point 5 or (2 It can be determined by knowing the subnetwork address to which the access point 5 belongs. In addition, if it is in a position where communication can be performed simultaneously with a plurality of accelerator points 5, the position detection is further performed by determining which one of the access points 5 is closer based on the radio wave intensity measured by the radio wave intensity measuring unit 691. May be performed.

  In step S <b> 22, the control unit 64 transmits the “position information” acquired in step S <b> 21 and the “cassette ID” of the radiation image detection apparatus 6 to the management server 2.

  In step S23, the console ID is specified. The console ID is identified by referring to a reference table set in advance by the management server 2 to acquire console ID information corresponding to the position information from the received position information. For example, when the position information is the shooting room 1, the console ID corresponds to the console of C01, and when the position information is the shooting room 2, the console ID corresponds to the console of C02. In step S24, registration is performed by associating the console ID acquired in step S12 with the cassette ID transmitted from the radiation image detection apparatus 6 in step S22.

  Note that the control flow from step S21 to step S24 is performed at regular intervals of, for example, several seconds, and the corresponding console ID is updated as needed in accordance with the change in the position of the radiation image detection device 6.

[Control flow when location information is updated]
Step S25 and subsequent steps are a control flow for explaining processing when the radiation image detection apparatus 6 is moved. The process will be described with reference to FIG.

  FIG. 7 is a diagram for explaining a flow of registration of imaging order information of the radiographic imaging system in the present embodiment. In the state shown in FIG. 6, that is, in the first state in which the radiation image detection device 6 (cassette ID: F01) is present in the imaging room 1, the imaging order information of the imaging orders ID001 to ID004 is the radiographic image detection device 6. It was registered in association with. The registration destination is the console 7a (console ID: C01) corresponding to the imaging room 1 according to the reference table.

  Next, the radiographer moves to another imaging room 2 with the radiation image detection device 6 (cassette ID: F01) ((1) movement in FIG. 7). In this case, the management server 2 updates the console ID corresponding to the change in the position information by the control flow of steps S21 to S24 of FIG. In the example shown in FIG. 7, the console ID of the console 7b corresponding to the photographing room 2 is C02.

Next, when the management server 2 determines in step S25 that the correspondence between the cassette ID and the console ID is different from the previously registered content (step S25: Yes), the management server 2 performs the following update registration control flow (FIG. 5). 7 (2) Update of photographing order information).
(1) The updated console ID (C02) is transmitted to the radiation image detection apparatus 6 (cassette ID: F01) (step S26).
(2) To the new console 7b (console ID: C02), the cassette ID (F01) and photographing order IDs 001 to 004 (display field h22 in FIG. 6) associated with the cassette ID are transmitted. (Step S27).
(3) Further, a command for deleting the registered imaging order information of (2) is transmitted to the console 7a (console ID: C01) before update.

  The radiation image detection apparatus 6 (cassette ID: F01) registers the console ID transmitted from the management server 2 in step S26 (step S28), and the console 7 (console ID: C02) transmits from the management server 2 in step S27. The cassette ID and the imaging order information associated therewith are registered (step S29). The above is the control flow regarding update registration of imaging order information.

[Control flow for shooting]
FIG. 8 is an explanatory diagram of a control flow related to imaging performed by the radiographic image capturing system. It is a continuation of the control flow shown in FIG.

  In step S <b> 41, the radiologist performs radiographing along radiographing order information using the radiographic image detection device 6. The acquired radiation image data is stored in the storage unit 60. If it is necessary to perform a plurality of imaging, the imaging is repeated to acquire a plurality of radiation image data.

  In step S42, the radiologist issues a transmission trigger instruction, and based on the transmission trigger, the radiological image detection apparatus 6 obtains in step S41 the console 7 to which the console ID (CS02) registered in step S27 is assigned. All the radiographic image data thus transmitted is transmitted together with its own cassette ID. The transmission trigger may be generated by, for example, a radiographer operating an operation button provided on the radiographic image detection device 6. The radiographic image detection device 6 is loaded in a cradle provided near the console 7. By doing so, a transmission trigger may be automatically issued.

  In the console 7 (console ID: C02) that has received the radiation image data, the radiation image data is displayed on the display unit 77 in the order of imaging (the order stored in the storage unit 60) (step S43). Further, the cassette ID transmitted together with the radiation image data and the imaging order information registered in step S29 corresponding to the cassette ID are also displayed on the display unit 77 (step S44).

  The radiologist confirms the displayed radiation image data and the imaging order information displayed together with the radiation image data. After confirming that the radiation image data is an image corresponding to the imaging order information, they are associated with each other (step S45), and the imaging ends.

  The associated radiographic image data may be transmitted from the console 7 to the management server 2 and stored in the storage device 21.

  In the present embodiment, it has been described that the control flow of step S21 to step S24 is appropriately performed at a fixed period. However, the present invention is not limited to this, and “stores one radiation image data acquired in step S41. You may make it carry out every time it memorize | stores in the part 60. FIG. As a result, the number of times the position information is detected and the position information is transmitted can be reduced, so that the life of the rechargeable battery of the power supply unit 67 can be extended.

  According to the present embodiment, in a radiographic imaging system using a portable FPD, the radiographic image data acquired by radiographing can be easily associated with the console even when moving between radiographing rooms. It is possible to provide a radiographic imaging system that can be easily associated with radiographic image data.

FIG. 9 is an explanatory diagram of a control flow performed by a radiographic image capturing system according to another embodiment. In the control flow shown in the figure, the console 7 associated with the movement of the position of the radiation image detection apparatus 6 is updated, but the update of the imaging order information is omitted. In the radiographic image capturing system according to another embodiment, the configuration of the main body is the same as that shown in FIGS. In the control flow shown in FIG. 9, steps common to the control flow shown in FIG. 4 or FIG.

  In step S230, the cell region is determined from the position information received from the radiation image detection apparatus 6. Here, the “cell area” is obtained by dividing a geographical area in which wireless communication is possible between any one of the plurality of access points 5 and the wireless communication unit 69 of the radiation image detection apparatus 6. In the example shown in FIG. 1, an area including the imaging room 100a, the imaging room 100b, and the imaging room 100c is a “geographical area that can be wirelessly communicated with a radiographic imaging system”, and the imaging room 100a, the imaging room 100b, and the imaging The chamber 100c is a “cell region”.

  In step S230, if the management server 2 determines that the position information of the radiation image detection device 6 is a cell area corresponding to the imaging room 100a, for example, the console ID associated with the cell area in FIG. In the example shown in FIG. 1, CS01) is acquired.

  In step S24, registration is performed by associating the cassette ID transmitted in step S22 with the console ID acquired in step S231. In this case, substantially the same information is maintained if it is the same as the previous registration information.

  Steps S26 to S43 are the same as the control flow shown in FIG. In step S440, the radiographer operates the input operation unit 78 of the console 7 to obtain the imaging order information by having the imaging order information stored in the storage device 21 of the management server 2 transmitted.

  The control unit 74 of the console 7 causes the display unit 77 to display a list of the imaging order information acquired in step S440 and the radiation image data acquired in step S41. In step S450, the radiologist operates the input operation unit 78 to associate the imaging order information with the image data, and the process ends.

  According to the present embodiment, in a radiographic imaging system using a portable FPD, the radiographic image data acquired by radiographing can be easily associated with the console even when moving between radiographing rooms. It is possible to provide a radiographic imaging system that can be easily associated with radiographic image data.

  In the above embodiment, when the shooting room is moved, the shooting order information is deleted from the console 7 that has been registered first, and additionally registered to a new console 7. If radiographing order information is displayed in common and one radiographer has selected radiographing order IDs 001 to 004, if the screen of FIG. This is preferable because it is possible to prevent an engineer from working on the same shooting order. In this case, when the radiologist moves through the radiographing room and associates the new console 7 with the radiographing order IDs 001 to 004, the radiographic image detection device 6 stores the image data to the new console 7. Is sent.
