Description

  The present invention relates to a medical image system and an image viewer terminal.

  In the medical field, digitization of medical images taken of patients has been realized. For example, based on imaging order information indicating that a patient is to be imaged, the image is captured by an image generation device (modality) such as a CR (Computed Radiography) device, a CT (Computed Tomography) device, or an MRI (Magnetic Resonance Imaging) device, and digitized. The medical image thus obtained is stored and managed in a PACS (Picture Archiving and Communication System) that is an image server together with incidental information such as patient information and examination information.

  In recent years, photographing order information is transmitted not only to the modality but also to the PACS and stored. Therefore, by accessing the PACS, it is possible to refer to shooting conditions, shooting status information, and the like that are not included in the incidental information but are included only in the shooting order information. Further, each information between the imaging order information and the supplementary information of the medical image is compared (verified). As a result, if the two are inconsistent, the supplementary information can be corrected.

For example, examination order information (imaging order information) and image attribute information (accompanying information) are compared, and the patient attribute information, examination type, and examination date included in each information are set to “match”, otherwise A technique is disclosed in which “mismatch” is set, and in the case of mismatch, both are automatically or semi-automatically matched (see Patent Document 1).

  Further, the control unit 41 generates a DICOM image data acquisition request based on an operation signal from the operation unit 42 by a user operation. Then, the control unit 41 transmits the generated DICOM image data acquisition request to the image server 30 via the communication unit 44. Then, when receiving the DICOM image data from the image server 30 via the communication unit 44, the control unit 41 stores (saves) the received DICOM image data in the storage unit 46.

  When the order-related information or DICOM image data received via the communication unit 44 is stored, the control unit 41 performs imaging order collation display processing.

  The imaging order collation display processing is based on the imaging order related information and DICOM image data stored in the storage unit 46, the imaging implementation status in the modality 20, the DICOM image acquisition status in the interpretation terminal 40, the imaging order information and DICOM. This is processing for displaying the matching status with image data on the display unit 43 as a photographing order list.

  If there is no DICOM image data corresponding to the order-related information object as a result of the search in step S1 (step S2; No), the control unit 41 sets the value of the field “image acquisition” of the corresponding record in the imaging order list display table 461. Is “not yet” (step S3). Also, the control unit 41 sets the value of the field “consistency” of the corresponding record in the imaging order list display table 461 to “-” (step S4).

  As a result of the search in step S1, if there is DICOM image data corresponding to the order-related information object (step S2; Yes), the control unit 41 sets the value of the field “image acquisition” of the corresponding record in the imaging order list display table 461. Is “completed” (step S5). Then, it is determined whether or not there is consistency between the order related information object and the DICOM image data corresponding to the order related information object (consistency check is performed) (step S6). Specifically, the control unit 41 includes predetermined items (for example, “patient name” included in the patient information and / or examination information included in the order-related information object and the patient information and / or examination information included in the DICOM image data. Or the like) is determined to match.

  As a result of the consistency check in step S6, when the consistency is not found (step S7; No), the control unit 41 sets the value of the field “consistency” of the corresponding record in the imaging order list display table 461 to “none”. (Step S8). When the consistency is found as a result of the consistency check in step S6 (step S7; Yes), the control unit 41 sets the value of the field “consistency” of the corresponding record in the imaging order list display table 461 to “present”. (Step S9).

  After setting the value of the field “consistency” of the corresponding record in the imaging order list display table 461 in step S4, step S8, and step S9, the control unit 41 stores the order related information object to be processed next as the storage unit. Whether it is stored in 46 (step S10). As a result of the determination, when the order related information object to be processed next is stored, the control unit 41 searches for DICOM image data corresponding to the order related information object to be processed next (step S1). ). In this way, the same processing is repeated for all order-related information objects stored in the storage unit 46, that is, order-related information objects corresponding to all the records in the imaging order list display table 461.

  If the order related information object to be processed next is not stored as a result of the determination in step S10 (the same processing was performed on the order related information objects corresponding to all the records in the imaging order list display table 461). ), The control unit 41 causes the display unit 43 to display a shooting order list screen (see FIG. 7) based on the shooting order list display table 461, shooting order related information, and DICOM image data (step S11). The photographing order collation display process is thus completed.

[Screen example]
Next, the imaging order list screen 431 displayed on the display unit 43 of the interpretation terminal 40 will be described with reference to FIG. As shown in FIG. 7, the imaging order list screen 431 includes imaging items including “patient ID”, “patient name”, “examination date”, “imaging execution”, “image acquisition”, and “consistency”. Contains an order list d1. The item “examination date” of the imaging order list d1 is an item indicating the scheduled imaging date of the patient, and corresponds to the “examination date” included in the examination information of the order list related information. The item “Implementation of imaging” is an item indicating whether or not imaging of a patient is completed, and corresponds to imaging status information of order list related information. The item “image acquisition” is an item indicating whether or not DICOM image data has been acquired from the image server 30, and corresponds to the field “image acquisition” of the imaging order list display table 461.

[Specific operation of each device in the medical imaging system]
Next, a specific operation of processing executed in the medical image system 100 will be described.

  FIG. 8 is a ladder chart showing processing executed in the medical image system 100. First, the RIS 10 generates imaging order information and transmits the imaging order information to the modality 20 (step S101).

  When receiving the imaging order information, the modality 20 images the patient based on the imaging order information and generates DICOM image data (step S102). The modality 20 transmits the generated DICOM image data to the image server 30 (step S103). Then, the image server 30 stores the DICOM image data. In addition, the modality 20 transmits a photographing completion notification to the RIS 10 (Step S104). When the RIS 10 receives the shooting completion notification, the RIS 10 changes the value of the shooting status information included in the corresponding shooting order information from “not yet” to “completed” (step S105).

  The image interpretation terminal 40 generates an order related information acquisition request and transmits it to the RIS 10 (step S106). When receiving the order related information acquisition request, the RIS 10 transmits the corresponding order related information to the interpretation terminal 40 (step S107).

  When the image interpretation terminal 40 receives the order related information, it performs a photographing order collation display process (step S108). In the imaging order collation display processing, each item of the imaging order list record corresponding to the order related information object related to one examination performed in step S102 is “imaging executed: completed” “image acquisition: not yet” “consistency: -"

  Then, the image interpretation terminal 40 generates a DICOM image data acquisition request based on the user operation and transmits it to the image server 30 (step S109). When receiving the DICOM image data acquisition request, the image server 30 transmits the corresponding DICOM image data to the image interpretation terminal 40 (step S110).

  When receiving the DICOM image data, the image interpretation terminal 40 performs a photographing order collation display process (step S111). In the imaging order collation display processing, each item of the imaging order list record corresponding to the order related information object related to one examination performed in step S102 is “imaging execution: completed” “image acquisition: completed” “consistency: Yes ". If an error occurs when the DICOM image data is generated in the modality 20 and the incidental information is set with an incorrect value, the “consistency: none” is set. For example, there is a case where information that should be “patient name: Taro Yamada” is missing one character, such as “patient name: Taro Yamada”.

  As described above, according to the first embodiment, the radiogram interpretation terminal 40 transmits an order related information acquisition request to the RIS 10 and acquires the order related information from the RIS 10. The image interpretation terminal 40 transmits a DICOM image data acquisition request to the image server 30 and acquires DICOM image data from the image server 30. Then, the interpretation terminal 40 displays an interpretation order list screen 431 including the interpretation order list d1 based on the order related information and the DICOM image data.

  By the display of the interpretation order list d1, the interpretation terminal 40 can refer to information relating to the interpretation order.

  Further, an interpreting doctor who is a user of the interpretation terminal 40 can know whether or not DICOM image data has been acquired from the image server 30 based on the value of the item “image acquisition” in the interpretation order list d1.

  Further, an interpreting physician who is a user of the interpretation terminal 40 can know whether or not imaging based on the imaging order has been performed in the modality 20 based on the value of the item “Implementing Imaging” in the interpretation order list d1.

  Further, the image interpretation doctor who is the user of the image interpretation terminal 40 can know whether the DICOM image data received from the image server 30 is consistent or not from the value of the item “consistency” in the image interpretation order list d1.

  The interpretation terminal 40 directly transmits an order related information acquisition request to the RIS 10 to acquire the order related information. Therefore, the interpretation terminal 40 can acquire the latest information managed by the RIS 10. Therefore, an interpreting doctor who is a user of the interpretation terminal 40 can refer to the latest imaging state information and the like.

  Note that the image interpretation terminal 40 may be configured to display patient information and examination information included in the order related information received from the RIS 10 together with supplementary information of DICOM image data.

  Upon receiving the imaging order information, the modality 20 images the patient based on the imaging order information and generates DICOM image data (step S202). The modality 20 transmits the generated DICOM image data to the image server 30 (step S203). Then, the image server 30 stores the DICOM image data. Further, the image server 30 changes the value of the shooting status information included in the corresponding shooting order information from “not yet” to “completed” (step S204).

  The interpretation terminal 40 generates an order related information acquisition request and transmits it to the image server 30 (step S205). When receiving the order related information acquisition request, the image server 30 transmits the corresponding order related information to the radiogram interpretation terminal 40 (step S206).

  When the image interpretation terminal 40 receives the order related information, it performs a photographing order collation display process (step S207). In the imaging order collation display processing, each item of the imaging order list record corresponding to the order related information object related to one examination performed in step S202 includes “imaging execution: completed”, “image acquisition: not yet”, and “consistency: -"

  Then, the image interpretation terminal 40 generates a DICOM image data acquisition request based on the user operation, and transmits it to the image server 30 (step S208). When receiving the DICOM image data acquisition request, the image server 30 transmits the corresponding DICOM image data to the image interpretation terminal 40 (step S209).

  When receiving the DICOM image data, the image interpretation terminal 40 performs a photographing order collation display process (step S210). In the imaging order collation display processing, each item of the imaging order list record corresponding to the order related information object related to one examination performed in step S202 is “imaging execution: completed”, “image acquisition: completed”, “consistency: Yes ". If an error occurs when the DICOM image data is generated in the modality 20 and the incidental information is set with an incorrect value, “consistency: none” is set. For example, there is a case where information that should be “patient name: Taro Yamada” is missing one character, such as “patient name: Taro Yamada”.

  As described above, according to the second embodiment, the image interpretation terminal 40 transmits an order related information acquisition request to the image server 30 and acquires the order related information from the image server 30. The image interpretation terminal 40 transmits a DICOM image data acquisition request to the image server 30 and acquires DICOM image data from the image server 30. Then, the interpretation terminal 40 displays an interpretation order list screen 431 including the interpretation order list d1 based on the order related information and the DICOM image data.

  By the display of the interpretation order list d1, the interpretation terminal 40 can refer to information relating to the interpretation order.

  The description in each of the above embodiments is an example of the medical image system according to the present invention, and the present invention is not limited to this. The detailed configuration and detailed operation of each device constituting the system can be appropriately changed.

  For example, in each of the above-described embodiments, an example in which a ROM is used as a computer-readable medium storing a program is disclosed, but the present invention is not limited to this example. As other computer-readable media, a non-volatile memory such as a flash memory and a portable recording medium such as a CD-ROM can be applied. A carrier wave (carrier wave) is also applicable as a medium for providing program data via a communication line.
