Description

  The present invention relates to a medical image management system that acquires medical images used for medical diagnosis. Specifically, the present invention relates to a technique for managing image information in a combined inspection using a plurality of modalities.

  In recent years, the processing speed of computers has improved, and in the field of medical images, X-ray diagnostic apparatuses, X-ray CT (Computed Tomography: X-ray computer tomography) apparatuses, MRI (Magnetic Resonance Imaging) apparatuses, ultrasonic diagnostics. Various medical imaging diagnostic modalities have emerged, such as devices (Ultrasonic diagnostic equipment) and NM (Nuclear Medicine).

  Thus, with the appearance of various modalities, the medical images and moving images that are formed are diversified. Since the generated medical images are compared with each other and diagnosed, they are managed in common within medical institutions such as hospitals.

  For example, HIS (Hospital Information System), RIS (Radiology Information System), or PACS (Radiology Information System) can be used as a network for exchanging data handled in this medical institution between each device and each device. Picture Archiving and Communication System (medical image storage communication system) and the like have come to be formed.

  HIS accepts a large number of patients (general reception), processes the reception to the department in charge such as internal medicine and surgery, manages the patient's personal information (name, age, address, visit history, treatment status) Accounting for medical expenses.

  RIS, in cooperation with HIS and PACS online, consistently handles medical appointments by medical equipment such as medical diagnostic imaging equipment in the radiology department, acceptance of examinations, interpretation of examination data, storage, and accounting for medical days. Support system to perform.

  PACS is a system that has an image server and can digitally store, communicate, display, and interpret images obtained by various diagnostic imaging devices in cooperation with HIS, RIS, and the like as described above. By using a large-capacity storage medium high-speed communication network, thin multi-screen display, application software, etc. and linking with PACS, it is possible to efficiently process medical image data, which has a huge amount of data, without degrading the image quality. It becomes.

  By the way, while the medical image diagnostic methods are diversified as described above, each medical image diagnostic apparatus can be used by using a specific medical image diagnostic apparatus and combining separate medical image diagnostic apparatuses. A combined examination for performing medical care on a specific part of a patient (subject) by utilizing each characteristic has been performed. In this way, in the field of medical image diagnosis, performing medical treatment by combining existing modalities makes it possible to make up for the lack of performance in each modality while taking advantage of the characteristics of each modality. This leads to improved accuracy.

  For example, conventionally, angiographic examination method that forms a two-dimensional image using an X-ray diagnostic apparatus has been used in contrast examination of a circulatory organ when imaging a blood flow state of a patient. One example is that an IVR-CT (Interventional Radiology-Computed Tomography) / Angio system has been used to image a smooth blood flow.

  In the IVR-CT / Angio system, an angiographic examination system using an X-ray diagnostic apparatus and a CT system are combined in the same examination room, and a CT examination is performed under the angiographic examination to perform medical care. By using CT, the positional relationship between blood vessels and lesions can be grasped three-dimensionally, and CT-Angio tests that have been performed by transferring the subject can now be performed in one imaging room. . In addition, it is possible to repeatedly obtain excellent image information of each medical image diagnostic apparatus in a short time, and to accurately depict complex and delicate blood vessels, advanced IVR technology (medical image diagnosis technology to reduce the burden on patients) It is a system that supports technology that makes full use of the treatment.

  In addition, SPECT-CT combining SPECT and X-ray CT apparatus for performing single photon emission tomography, PET-CT, PET apparatus and MRI apparatus combining PET and X-ray CT apparatus for performing positron emission tomography There are also combined examinations such as PET-MRI in combination with which a plurality of modalities are combined for medical treatment. These may be combined with an X-ray CT apparatus or an MRI apparatus to compensate for the possibility that shape information and position information may not be obtained accurately from an image generated by a nuclear medicine apparatus.

  These combined examinations generate medical image data from multiple modalities, but medical image data generated from these multiple modalities is used as a combined examination. It is not used as a reference but is used as one combined test.

  In addition, a management system that includes schedule information for complex examinations is not managed individually for each of a plurality of modalities, but a method for managing schedule information relating to the same complex examination in an integrated manner has been proposed ( For example, Patent Document 1).

JP-A-2005-261951

  Incidentally, the medical image data generated by the medical image diagnostic apparatus is stored, displayed, managed, etc. in some form regardless of whether or not it is a combined examination. Here, an example is given in which medical image data is managed using HIS or RIS.

  Medical diagnostic imaging equipment is usually communicable with the RIS over a network, and orders (reservations) are entered into the RIS through the HIS from surgical, internal medicine, and other department terminals, and examinations and radiographing are performed based on the order. Do. The generated medical image data is recorded and stored in an image server, PACS, and the like. When browsing, medical images and moving images are called up and displayed based on the recorded medical image data.

  For the management of these medical image data, patient information (patient name, ID, etc.) for identifying the patient and examination information (examination date, examination modality, etc.) for identifying the examination are attached and displayed in a list. ing. For example, the medical image corresponding to the selection is displayed when the user selects an inspection item in any one row from the display of the list for each modality arranged in the row direction as shown in FIG. It is like that.

  In this way, the inspection information relating to a plurality of modalities is displayed as a list independently for each modality. Therefore, when the user intends to browse the medical image data related to the above-described combined examination, the user himself has to determine whether the desired medical image is a combined examination based on patient information, examination information, or the like.

  However, it is troublesome for a doctor or the like to make a determination based on patient information or examination information displayed in a list when determining whether or not the examination is a combined examination. Further, when a combined test and another test are performed on the same patient on the same day, it is difficult to clearly distinguish whether the test is for each modality or the combined test. In such a case, there is a risk that one of the inspections may be mistakenly overlooked.

  Even if it is recognized in advance that it is a combined test, it must be determined from the patient information and test information of each test, and it is desired for each modality related to the same combined test. The medical image must be selected, which is complicated.

  Therefore, when a combined inspection is performed, there is a request for clearly displaying that it is a combined inspection, instead of displaying the inspection information related to the combined inspection as individual inspections for each modality. It was.

  In addition, the order for the examination is a distinction between the combined examination and the other examination at any stage from various medical departments to entering each modality through HIS and RIS. However, information that certain order information is related to the combined examination has not been effectively used after the medical image data is generated. Note that the order information is information including information on a patient for performing an examination with a desired modality, an examination target region, and examination conditions, and the order is an examination execution instruction based on the order information.

  The present invention has been made in view of the above problems, and the purpose thereof is to provide a technology that clearly associates that individual inspection information and the like related to the above-described combined inspection is related to the combined inspection. With the goal. Furthermore, by displaying the associated information, it is possible to recognize that the combined examination is performed without the judgment of the user viewing the medical image or the like, so that the complexity is avoided and the user is the combined examination. It is an object of the present invention to provide a medical image management system that prevents oversight.

  Another object of the present invention is to effectively use information generated at the time of examination order and avoid complicated work without searching and displaying medical images for the same combined examination for each modality. It is to provide a medical image management system capable of

This makes it possible to effectively use information generated at the time of the inspection order and avoid complicated work.

  Hereinafter, a medical image management system according to an embodiment of the present invention will be described with reference to the drawings.

[System configuration]
(Configuration of medical image management system 1)
FIG. 1 is a diagram for explaining a schematic configuration of a medical image management system 1 according to an embodiment of the present invention. As shown in FIG. 1, the medical image management system 1 is configured by connecting a HIS 10, a RIS 20A, a combined examination control unit 20B, an examination apparatus unit 20C, and an image server 30 through a network. An image display apparatus 40 in FIG. 1 is an example of an apparatus that indicates how information such as medical images generated by the medical image management system 1 is displayed and used for diagnosis. Note that DICOM (Digital Imaging and Communications in Medicine) may be used as a network standard of the medical image management system 1 according to this embodiment.

(Configuration of HIS10)
The HIS 10 includes a doctor terminal 11, an HIS terminal not shown, a reception terminal, an HIS server, and the like. This HIS10 is an in-hospital information system that stores patient information related to patients such as patient ID, name, gender, blood type, accounting information such as medical expenses, and issuance of X-ray examination orders. It is a system that manages it centrally. The doctor terminal 11 is an example of an apparatus that orders the medical image management system 1 (such as a doctor terminal for internal medicine, surgery, pediatrics, etc.).

  For example, as shown in FIG. 1, the HIS 10 is used by a user (such as a doctor) from a doctor terminal (such as the doctor terminal 11 in FIG. 1) to examine information (patient ID, patient name, examination date, modality information, etc.) Upon receiving the order information of the examination specified, the order information is transmitted to the RIS 20A.

  When the user specifies examination information for the same patient, for example, patient ID, patient name, examination date, etc. are commonly specified regardless of differences in modalities such as the PET apparatus 26 and the X-ray CT apparatus 27. . However, on the other hand, the examination type (modality) is also specified, but in this case, even for the same patient, this examination type is specified according to the change in the examination method, A suitable inspection type is specified depending on the difference in modality.

  Here, when the user specifies the details of the order information, if the inspection to be performed is a combined inspection such as a PET-CT inspection, the user is a combined inspection in the HIS 10 when specifying the order information of the inspection. To that effect. If it is determined that it is a combined inspection, the order information is transmitted to the RIS 20A as order information for the combined inspection.

(Configuration of RIS20A)
The RIS 20 </ b> A is a radiology information management system, and includes a RIS control unit 21 and an accompanying information addition unit 22. The RIS 20A includes examination reservation information, examination acceptance information, medical image data generated by a medical image diagnostic apparatus, and the like by an examination apparatus unit 20C configured to include a CR (Computed Radiography) apparatus, a SPECT-CT apparatus, and the like. It is a system that comprehensively manages information in the radiology department.

  As shown in FIG. 1, the RIS 20A receives, as an example of its operation, the medical image diagnostic apparatus (for example, FIG. 1) in the inspection apparatus unit 20C that receives the order information of the inspection by the inspection apparatus unit 20C from the HIS 10 and corresponds to the order information. The order information is transmitted to the RIS control unit 21 for inspection by the PET apparatus 26, the X-ray CT apparatus 27, and the like.

  At this time, the RIS control unit 21 decodes the received order information. As a result of decoding by the RIS control unit 21, if the order information is for the combined inspection, the additional information is added to the order information by the additional information adding unit 22 of the RIS 20A, and then transmitted to the combined inspection control unit 20B. Note that when order information is transmitted to the composite examination control unit 20B, examination information (patient ID, examination date, modality, etc.) is generated in order to manage and communicate the image as a DICOM image after the image relating to the order is generated. May be added to the tag information (DICOM Tag).

  The addition of the supplementary information is information that specifies the X-ray CT apparatus 27, which is the other modality of the combined inspection, with respect to the PET order information transmitted to the PET apparatus 26 in the combined inspection such as PET-CT. Means to add. The information specifying the X-ray CT apparatus 27 refers to ID information indicating the X-ray CT apparatus 27, for example. Similarly, information specifying the PET apparatus 26 (for example, ID information indicating the PET apparatus 26) is added to the CT order information transmitted to the X-ray CT apparatus 27 by the incidental information adding unit 22.

(Configuration of combined inspection control unit 20B)
The composite inspection control unit 20B includes an operation unit 23 and an image device control unit 24, receives order information from the RIS 20A, and transmits the order information to the inspection device unit 20C. Further, the medical image data received from the inspection apparatus unit 20C is processed and transmitted to the inspection apparatus unit 20C.

  The operation unit 23 in the combined examination control unit 20B is for operating a medical image diagnostic apparatus such as the PET apparatus 26 and the X-ray CT apparatus 27 in the examination apparatus unit 20C. In addition, the imaging apparatus control unit 24 adds the above-described examination information, incidental information for specifying the X-ray CT apparatus 27 by the incidental information adding unit 22, and the like to the PET apparatus 26 according to the operation of the operation unit 23 by the user. The PET order information is transmitted. Similarly, the image apparatus control unit 24 transmits CT order information to which additional information specifying the PET apparatus 26 is added to the X-ray CT apparatus 27.

  Further, the image device control unit 24 responds to the operation of the operation unit 23 by the user, and the like, the image generation unit 25a in the inspection device unit 20C, the image generation unit 28a corresponding to the PET device 26, and the image corresponding to the X-ray CT device 27. The generation unit 28b and other units of the inspection apparatus unit 20C are collectively controlled.

(Configuration of inspection device unit 20C)
The inspection device unit 20C includes an imaging unit 25, image generation units 28a and 28b, an information combination unit 29a corresponding to the image generation unit 28a, and an information combination unit 29b corresponding to the image generation unit 28b. . The inspection apparatus unit 20C is, for example, a medical image diagnostic apparatus. FIG. 1 illustrates a PET-CT including a PET apparatus 26 and an X-ray CT apparatus 27 as an example of the inspection apparatus unit 20C. However, as the inspection apparatus unit 20C, not only an inspection apparatus related to a combined inspection such as an inspection performed by combining SPECT-CT / IVR-CT / nuclear medicine and MRI, an ultrasonic diagnostic apparatus related to other inspections, There are various apparatuses such as an X-ray CT apparatus, an MRI apparatus, and a DF apparatus.

  The inspection apparatus unit 20C receives order information from the composite inspection control unit 20B through the image apparatus control unit 24. In addition, when receiving the order information, the inspection apparatus unit 20C transmits a necessary instruction according to the order from the user to each apparatus of the imaging unit 25. Necessary instructions are instructions necessary for acquisition and generation of images such as imaging of a patient (subject). In FIG. 1, PET order information for instructing imaging by the PET apparatus 26 is sent to the PET apparatus 26, and CT order information for instructing imaging by the X-ray CT apparatus 27 is sent to the X-ray CT apparatus 27. Each device performs imaging of a patient based on the order information.

  Each imaging data obtained from imaging of the patient by each device is transmitted to the image generation units 28a and 28b of the inspection device unit 20C. In the example of FIG. 1, the image generation unit 28 a generates medical image data based on the imaging data from the PET apparatus 26 and the conditions of the PET order information. Similarly, the image generation unit 28b generates medical image data based on the imaging data from the X-ray CT apparatus 27 and the conditions of the CT order information.

  When medical image data is generated by the image generation unit 28a, the information combining unit 29a adds examination information to the generated medical image data. Similarly, when medical image data is generated by the image generation unit 28b, the information combining unit 29b adds examination information to the generated medical image data. The examination information added in this way is information added to the order information corresponding to the medical image data.

  The image device control unit 24 in the composite examination control unit 20B determines whether the generated medical image is related to the composite examination after adding examination information by the information combining units 29a and 29b. This determination is made based on the order information corresponding to the generated medical image data. For example, in the case of a combined examination by PET-CT as shown in FIG. 1, if incidental information for specifying the other X-ray CT apparatus 27 related to the combined examination is added to the PET order information transmitted to the PET apparatus 26, The image device control unit 24 determines that the generated medical image data is related to the combined examination.

  When the image device control unit 24 determines that the generated medical image data is related to the composite examination, the information combining unit 29a includes the additional information added to the order information corresponding to the medical image data, The medical image data is further combined. In the case of FIG. 1, the medical image data obtained by the PET apparatus 26 and the accompanying information specifying the X-ray CT apparatus 27 added to the PET order information are combined. In this case, similarly, the information combining unit 29b further combines the medical image data obtained by the X-ray CT apparatus 27 and the incidental information specifying the PET apparatus 26. Note that the information combined with the medical image data may be added with a DICOM Tag related to the other modality corresponding to the accompanying information instead of the accompanying information.

  When the medical image data is generated by the image generation unit 28a and the medical image data and the inspection information are combined by the information combining units 29a and 29b, the inspection apparatus unit 20C transmits the medical image data to the image server 30. . When the generated medical image data is related to the combined examination, the medical image data is transmitted after the medical image data and the incidental information are combined by the information combining units 29a and 29b.

(Configuration of the image server 30)
As shown in FIG. 1, the image server 30 includes an image server control unit 3 1 and a storage unit 32. The image server 30 is linked to the HIS 10, the RIS 20A, the inspection device unit 20C, the image display device 40, and the like. For example, medical image data obtained by the inspection device unit 20C (such as various medical image diagnostic devices) It is a system that can store, communicate, display, and interpret images.

  For example, as shown in FIG. 1, when receiving medical image data generated based on the imaging data of the PET apparatus 26 or the X-ray CT apparatus 27 from the inspection apparatus section 20C, the image server control section 31 stores the storage section 32. The data is stored independently. This medical image data is stored including examination information combined with the medical image data by the examination apparatus unit 20C. That is, the medical image data is stored in a systematic manner for each piece of information that specifies the patient ID, the patient's name, the examination date, and the modality included in the examination information. At this time, if the supplementary information is combined with the medical image data, the image server control unit 31 stores the medical image data in association with the supplementary information in the storage unit 32.

  The image server control unit 31 requests the list display (for example, the examination date “for the examination item, examination date, etc.) from the image display device 40 and each terminal (for example, the HIS 10 and the doctor terminal 11). 2005/12/10 "), the inspection information related to the specific item is read from the storage unit 32, and a list is generated in a predetermined format stored in advance (for example, 2 and 3).

  When the desired list is generated, it is transmitted as list display data that can be displayed to the list display requesting side. At that time, by designating any of the displayed examination information, the image data based on the designated examination information can be read from the storage unit 32, so that the examination information and the address of the medical image data are associated with each other.

  Further, the image server control unit 31 stores a list (for example, FIG. 2 and FIG. 3) organized with examination information and incidental information for each patient information related to the medical image data stored in the storage unit 32. It may be left. Furthermore, the image server control unit 31 associates the inspection information related to the combined inspection with the incidental information when the storage unit 32 includes the inspection information related to the combined inspection in the individual information constituting the list. Store the data so that it can be read.

  When a request (parameter) of medical image data relating to a specific item specified on the displayed list is received from the image display device 40 or each terminal (for example, the HIS 10 or the doctor terminal 11), the image server The control unit 31 reads out medical image data according to the request from the storage unit 32 and transmits it as data that can be displayed on the desired list display means side. If the requested medical image data is related to the combined examination, the image server control unit 31 stores the medical image related to the additional information from the storage unit 32 based on the additional information combined with the requested data. Data is also read and transmitted.

  Here, examples of the list are shown in FIGS.

  FIG. 2 is a diagram illustrating an “inspection date list” that is a list of inspection information for each inspection date. For this “examination date List”, for example, a search request and a list request are made by designating the date “2005/12/10” from the image display device 40, and the image server control unit 31 accesses the storage unit 32 to perform a date search. It is an example of the list created by performing. This list is organized for each examination date, and each patient's ID, patient name, examination date, examination type, and supplementary information are shown for each line (horizontal direction). The columns (vertical direction) in this list are organized by inspection type (type of modality used).

  Further, “SPECT” and “CT” are represented in the examination information column (rightmost column) relating to the patient ID “0000001” in the front row in FIG. This indicates that the patient with the patient ID “0000001” has undergone the examination by “SPECT-CT”, that is, the combined examination. In this case, information for specifying examinations “SPECT” and “CT” of “SPECT-CT” is also shown. That is, the combined inspection is also expressed as this one inspection.

  In addition, in the column below the column displaying the information of the “SPECT-CT” examination received by the patient with the patient ID “0000001”, the “CR” examination received by the patient with the same patient ID “0000001” is displayed. Information is displayed. Although only “CR” is displayed in the inspection information column of this column, this indicates that an inspection that is not a combined inspection is performed for the inspection type displayed in this row.

  FIG. 3 is a diagram showing “CT List” which is a list of examination information for each examination using the X-ray CT apparatus. For this “CT List”, for example, a search request and a list request are made by designating the examination type “CT examination” from the image display device 40, and the image server control section 31 accesses the storage section 32 to perform a modality search. It is an example of the created list. Also in this list, the ID for each patient, the patient's name, the examination date, the examination type, and accompanying information are displayed in a horizontal row. “CT List” in FIG. 3 is grouped for each modality and grouped for each patient specific information (name, ID, etc.). Others are the same as “Examination Date List” in FIG.

  As can be seen from FIG. 2 or FIG. 3, even when the combined inspection is performed, the other PET inspection that has been combined with the CT inspection is displayed together, so that the combined inspection is overlooked. There is no fear.

(Configuration of image display device 40)
The image display device 40 includes an image display unit 41, a control unit 43, an operation unit 42, and the like. The image display device 40 requests a list (for example, the list in FIGS. 2 and 3) or a medical image based on examination information stored in the storage unit 32 by accessing the image server 30 in order to make a diagnosis. Display these. The control unit 43 performs display control of the image display unit 41, control of the operation unit 43, control of information input / output, and the like.

  When a request for displaying a list (for example, “Examination Date List” in FIG. 2) is made to the image display device 40 by the operation of the operation unit 42 by the user, the control unit 43 The request is transmitted to the server 30. As described above, in response to the request, when the list display data of the list including examination information and the like is transmitted by the image server control unit 31, the image display device 40 receives the data received by the control unit 43. The image is displayed on the image display unit 41. At this time, when the data of the inspection information related to the composite inspection is included, the accompanying information is displayed together with the inspection information (for example, FIG. 2).

  Further, by operating the operation unit 42 or the like, for example, while displaying FIG. 2, the “inspection” item of the patient ID “0000001” is designated by a double click or the like with a pointing device or the like, and the desired image display device 40 When the request for displaying the medical image is made, the control unit 43 makes a request to the image server 30. As described above, the image server control unit 31 transmits desired medical image data in response to the request, and the control unit 43 causes the image display unit 41 to display the medical image in response to the request, as in the case of the list. At this time, when the requested medical image is related to the composite examination, the medical image read by the image server control unit 31 can also be displayed. The medical image includes both a still image and a moving image.

HIS10, RIS20A, combined examination control unit 20B, image server 30, image display device 40, and doctor terminal 11 have hardware configurations such as a computer having a CPU, RAM, ROM, HDD, user interface, communication interface, etc. Consists of. The doctor terminal 11 is also configured by a similar computer. Here, other descriptions of these hardware configurations are omitted.

[Operation]
The operation of the medical image management system 1 of the present embodiment as described above will be described. 4 to 7 show an operation in which a user such as a doctor instructs examination of a specific patient (subject), medical image data is generated based on the instruction, the medical image data is stored, and the medical image is browsed. 5 is a flowchart showing a series of operations of the medical image management system 1 for explaining the above. An example of the operation of the medical image management system 1 will be described based on these drawings.

(Step 1)
First, a user (such as a doctor) specifies examination information (modality, patient information, etc.) from the doctor terminal 11 (for example, a doctor terminal of a surgical system) in order to perform an examination using the examination apparatus unit 20C. This examination information is specified according to the result of diagnosing the patient. For example, when the user specifies order information as a combined inspection such as PET-CT, the order information includes information indicating the combined inspection. Further, when all items to be specified in the order information are specified by the user and the user instructs the doctor terminal 11 to transmit the order information, the order information is transmitted to the HIS 10.

(Step 2)
When receiving the order information of the examination from the doctor terminal 11 or the like, the HIS 10 decodes the received order information and determines whether the order information is related to the combined examination. This determination is made based on whether or not the order information includes information indicating a composite inspection.

(Step 3)
When the HIS 10 determines that the order information is related to the combined inspection (step 2; Yes), the HIS 10 transmits the order information to the RIS 20A as the order information related to the combined inspection.

(Step 4)
When the order information received by the HIS 10 is decoded and it is determined that the inspection related to the order information is not a combined inspection (step 2; No), the HIS 10 transmits the order information to the RIS 20A as order information that is not a combined inspection.

(Step 5)
When the order information is transmitted from the HIS 10 to the RIS 20A, the RIS control unit 21 determines whether the inspection related to the order information is a combined inspection. The determination of the RIS control unit 21 is performed by the RIS control unit 21 decoding the received order information. As a result of decoding by the RIS control unit 21, when the HIS 10 transmits the order information as the order information related to the combined inspection in step 3, the RIS control unit 21 determines that the order information is related to the combined inspection. Alternatively, when the order information is transmitted as the order information that is not the combined inspection in step 4, the order information is determined as the order information that is not the combined inspection.

(Step 6)
When the RIS control unit 21 determines that the RIS control unit 21 receives the order information received by the RIS 20A (step 5; Yes), the RIS control unit 21 adds the order information to the order information by the supplementary information adding unit 22. Thus, information specifying the other modality related to the same combined inspection is added. For example, in the case of a combined examination by PET-CT, information specifying the X-ray CT apparatus (inspection) is added to the order information for the PET apparatus 26. Similarly, the incidental information adding unit 22 adds information specifying the PET apparatus (inspection) to the order information for the X-ray CT apparatus 27.

(Step 7)
When the RIS control unit 21 determines in step 5 that the order information is not the combined inspection order information (step 5; No), or when additional information is added to the order information in step 6, the RIS control unit 21 Order information is transmitted to the inspection control unit 20B. The image device control unit 24 of the combined inspection control unit 20B transmits order information to the inspection device unit 20C when an operation instruction is given by the operation unit 23 by the user.

(Step 8)
When the inspection apparatus unit 20C receives the order information from the combined inspection control unit 20B, the image apparatus control unit 24 takes an image of the inspection apparatus (PET apparatus 26 or X-ray CT apparatus 27 in FIG. 1) corresponding to the order information. Make it possible. When imaging or the like becomes possible and the patient (radiologist) or the like images the patient, imaging data is transmitted from each examination apparatus to the image generation units 28a and 28b. When the image generation units 28a and 28b receive the imaging data, the image generation units 28a and 28b generate medical image data.

(Step 9)
When the medical image data is generated by the image generation unit 28a, the image device control unit 24 combines the examination information added to the order information related to the medical image data with the medical image data by the information combining unit 29a. . Similarly, the information combination unit 29b combines the medical image data from the image generation unit 28b and the examination information.

(Step 10)
When the medical image data and the examination information are combined by the information combining units 29a and 29b, the image apparatus control unit 24 has added incidental information to the order information based on the order information corresponding to the medical image data. Judge whether.

(Step 11)
If the image device control unit 24 determines that supplementary information has been added based on the order information corresponding to the generated medical image data (step 10; Yes), the information combining unit 29a or 29b causes the medical device control unit 24 to perform the medical information. The supplementary information is combined with the image data.

(Step 12)
When the image device control unit 24 determines that the supplementary information is not added to the order information corresponding to the medical image data generated in Step 10 (Step 10; No), or in Step 11, the supplementary information is attached to the medical image data. When the information is combined, medical image data combined with necessary information is transmitted to the image server 30.

(Step 13)
When the image server 30 receives the medical image data from the inspection apparatus unit 20C, the image server control unit 31 stores the combined examination information and incidental information together with the medical image data.

(Step 14)
When the user performs an operation of requesting a list display of examination information from the doctor terminal 11 or the image display device 40 by designating a specific item by using the operation unit 42 of the image display device 40, the control of the image display device 40 or the like The unit 43 or the like requests the image server 30 for information necessary for displaying the inspection information list.

(Step 15)
When the image server 30 receives a request for information necessary for list display, the image server control unit 31 searches the storage unit 32 for information on the specified inspection item from the stored inspection information and incidental information, and requests it. A predetermined list corresponding to the above is generated.

(Step 16)
When the predetermined list is generated by the image server control unit 31, the image server control unit 31 transmits the data of the list to the image display device 40 or the like, and the image display device 40 acquires the data of the list.

(Step 17)
When the control unit 43 or the like of the image display device acquires the data of a predetermined list corresponding to the display request from the image server 30, the list display data is transmitted to the image display unit 41, and the image display unit 41 receives it. A predetermined list is displayed. At this time, when the supplementary information is included in the list display data acquired from the image server 30, the image display unit 41 also displays the examination type corresponding to the supplementary information in the examination type item (for example, FIG. FIG. 3).

(Step 18)
When the user browses a desired medical image, for example, first, a list of examination information displayed on the image display unit 41 of the image display device 40 (or the image display unit of the doctor terminal 11 or the like) by the operation unit 42 or the like. One of the examination information or the like is selected, and medical image data for displaying a medical image is requested. For example, inspection information is selected by clicking the inspection item shown in FIG. 2 with a mouse or the like.

(Step 19)
When the user performs an operation for requesting desired medical image data from a list of examination information displayed on the image display unit 41 or the like, the control unit 43 or the like of the image display device 40 or the like combines the incidental information with the selected examination information. Judge whether it has been.

(Step 20)
If the control unit 43 or the like of the image display device 40 determines that the supplementary information is included in the examination information selected by the user (step 22; Yes), the examination information selected by the user with respect to the image server 30 And medical image data corresponding to the supplementary information included in the examination information is requested.

(Step 21)
When it is determined that the supplementary information is not included in the examination information selected by the user (step 22; No), the control unit 43 or the like sends medical image data corresponding to the examination information selected by the user to the image server 30. Request only.

(Step 22)
When the image server 30 receives a request for medical image data, the image server control unit 31 reads out the medical image data corresponding to the request from the storage unit 32 and transmits it to the image display device 40.

(Step 23)
When the control unit 43 of the image display device 40 (or the image display unit of the doctor terminal 11 or the like) acquires the medical image data corresponding to the display request from the image server 30, the medical image data is displayed on the image display unit 41. . At this time, when the supplementary information is included in the examination information selected by the user in step 21, a medical image corresponding to the selected examination information and a medical image corresponding to the included supplementary information are displayed together. It will be.

  The medical image management system 1 according to the present embodiment includes means for determining whether the order information is related to the combined inspection when transmitting the inspection order information to the inspection apparatus unit 20C, and based on the determination, the combined inspection The information specifying the examination type (modality) related to the other order information is added to the one order information related to the other order information as additional information and transmitted.

  Therefore, when the inspection apparatus unit 20C images a patient (subject) and medical image data is generated from the captured image data, it is possible to associate the medical image data with supplementary information related to the composite inspection. When storing or browsing image data, it is not necessary for a user (doctor, etc.) to refer to examination information (patient ID, examination date, etc.) included in the medical image data to determine whether the examination is a combined examination, Since it is clearly displayed that it is a combined inspection, it is possible to avoid complicated operations and avoid overlooking that it is a combined inspection by having to rely on the user's judgment.

  In addition, the medical image management system 1 according to the present embodiment is configured to store medical image data and supplementary information related to composite examination in association with each other. Therefore, when the user browses a list of examination information displayed on the image display unit or the like in order to search for medical image data, the examination information corresponding to the desired medical image data is included in the examination information list. Since the information is displayed in association with each other, it can be easily understood that it is a combined inspection.

  In addition, medical image data related to the composite examination and incidental information are stored in association with each other, and when a display request for a desired medical image related to the composite examination is requested, the medical image data corresponding to the supplementary information is displayed together with the medical image data related to the display request. Since the data is configured to be displayed, the medical image management system can automatically manage the data even if the medical image data related to the display request is not conscious of whether it is a combined examination.

[Modification]
The configuration of the medical image management system 1 according to the present embodiment described above is only one configuration example for carrying out the present invention. Therefore, modifications can be appropriately made within the scope of the gist of the present invention.

  In the above-described embodiment, the RIS server appends incidental information for specifying the other inspection related to the same combined inspection to the one order information related to the combined inspection by the additional information adding unit. However, common information may be added as supplementary information to all the order information related to the same combined inspection. Even in this modified example, it is possible to obtain the same effect as the medical image management system 1 described above.

  For example, based on the examination order information, the medical image diagnostic apparatus images a patient (subject) and generates medical image data, and then the common information added to the order information as supplementary information is displayed by the information combining unit. By combining with the generated medical image data, when the image server stores the medical image data, the medical image data can be stored in association with the common information combined with the medical image data. Become.

  Therefore, also in this modification, when a user browses a list of examination information in order to search for desired medical image data on the image display device, common information is associated with each examination information related to the complex examination. Since all the inspection information relating to the same combined inspection is displayed in a list in association with each other, it can be clearly displayed that it is a combined inspection.

  In addition, when a display request for medical image data related to a composite examination is made from this list, the image server uses the common information for the medical image data related to the display request and other medical image data related to the same composite examination based on the common information. Thus, it is possible to read out and transmit to the image display device, so that it is possible to prevent a situation where the combined inspection is overlooked.

  In the present embodiment, a system using a system such as HIS, RIS, or image server is used. However, the present invention may be a further subdivision of the medical image management system. Each system may be integrated and simplified. For example, it may be configured as a system in which the RIS and the image server are integrated or a system in which the HIS, the RIS and the image server are integrated. In this way, even when the medical image management system is complicated or simplified, according to the present invention, the medical image data generated from the medical image diagnostic apparatus and the incidental information indicating that it is a combined examination are combined. By doing so, it is possible to provide a medical image management system capable of avoiding complications and accurately grasping that it is a combined examination.

  The embodiment described above is described in order to facilitate understanding of the present invention, and is not described in order to limit the present invention.
