[First embodiment]
Hereinafter, an embodiment (first embodiment) when the medical image capturing apparatus of the present invention is applied to the PACS 30 of FIG. 1 will be described with reference to FIGS.

[System configuration of radiology system]
First, the outline of the radiology system 100 having the PACS 30 will be described with reference to FIG.

  FIG. 1 is a block diagram illustrating an example of a system configuration of a radiology system 100 in Hospital A. According to FIG. 1, the radiology system 100 includes an RIS 10, a modality 20, a PACS 30, and a client terminal 40. Each of the above devices is connected to be able to perform data communication via a communication network N such as a LAN (Local Area Network).

  The RIS 10 performs information management such as medical appointment reservation, diagnosis result report, results management, and material inventory management in the radiology department (radiology system 100). The RIS 10 transmits imaging order information generated in an electronic medical chart system (not shown) to the modality 20.

  The modality 20 is an imaging device that images a patient according to the imaging order information received from the RIS 10 and generates image data (medical image data) of a medical image. Further, the modality 20 generates incidental information related to the image data based on the photographing order information. Then, the modality 20 attaches additional information to the image data (hereinafter referred to as actual image data), generates DICOM image data that conforms to the DICOM standard, and transmits it to the PACS 30. As the modality 20, an imaging apparatus (medical image imaging apparatus) that captures various types of medical images, such as a CR apparatus, a CT apparatus, and an MRI apparatus, can be applied.

  FIG. 2 shows a data configuration diagram of DICOM image data generated by the modality 20. As described above, DICOM image data is composed of incidental information and actual image data. The incidental information includes patient information, examination information, series information, and image identification information.

The inspection information is information relating to the inspection such as an inspection ID for identifying the inspection, an inspection name, an inspection date and time, a reception number, an inspection purpose, and inspection contents. The series information is information on a series (unit) of a series of medical images for each modality generated in one examination, such as a series number, a modality name, a technique, an imaging part, an imaging direction, and an imaging engineer name. The image identification information is information related to a medical image such as an SOP instance UID that identifies an image, an image number, and an image size.

  Returning to FIG. 1, the medium M is a portable storage medium (CD-R, DVD-R, etc.) that stores DICOM image data. The medium M stores DICOM image data in accordance with a data structure defined by PHE of IHE and IHE-J. In the present embodiment, it is assumed that DICOM image data is written on the medium M in the radiology system in the hospital B different from the hospital A.

  FIG. 3 shows an example of patient information about the same patient included in the incidental information of DICOM image data generated at A hospital and B hospital.

  As shown in FIG. 3, the values of the patient information items for the same patient may differ between Hospital A and Hospital B. Specifically, since “patient ID” is an ID issued at each medical facility, the value is different from “1” for hospital A and “0002” for hospital B.

  The “patient name (Roman character)” has a different value from “TOKYO ^ TARO” in Hospital A and “TOKYOU ^ TAROU” in Hospital B. This is due to differences in character input by users such as radiographers in the modalities of each medical facility.

  In addition, “patient name (kana)” is displayed in half-width in hospital A and full-width in hospital B. “Patient name (kanji)” is blank in hospital A. These are due to differences in the modality vendors of each medical facility.

  As described above, if the medical facility or modality in which DICOM image data is generated is different, or if a user such as a radiographer operating the modality is different, even if the patient information of this DICOM image data is information on the same patient May be different.

  Returning to FIG. 1, the PACS 30 is a database system that stores and manages DICOM image data generated in the modality 20 and performs search and data analysis. The PACS 30 accumulates and stores the DICOM image data in, for example, a relational database based on incidental information included in the DICOM image data received from the modality 20. Then, the PACS 30 searches the DICOM image data using the patient ID, examination ID, or the like designated in accordance with an operation instruction from the image interpretation doctor or the like as a search key, and outputs it to the image viewer or imager. When the PACS 30 receives a DICOM image data acquisition request including a search key such as a patient ID and an examination ID from an external device, the PACS 30 searches for DICOM image data corresponding to the acquisition request and provides (transmits) it to the external device.

  The PACS 30 reads DICOM image data from the medium M, and stores and manages this DICOM image data together with the DICOM image data received from the modality 20. That is, the PACS 30 takes in DICOM image data read from the medium M.

  The client terminal 40 has a viewer function for displaying a medical image, and is a terminal used for interpretation by an interpreting doctor or the like. The client terminal 40 transmits a DICOM image data acquisition request to the PACS 30 and acquires DICOM image data corresponding to the acquisition request from the PACS 30.

In addition, the medical image capture program 351 and the control unit 31 cooperate to perform DICOM image data capture processing.

[Patient information extraction list generation process]
Next, a specific operation of the patient information extraction list generation process performed by the control unit 31 of the PACS 30 in cooperation with the medical image capture program 351 will be described with reference to FIG.

  When the media M is set in the media drive 36 and the media drive 36 reads DICOM image data from the media M, this patient information extraction list generation process is executed.

  As shown in FIG. 6, the control unit 31 extracts items “patient name (Roman character)”, “patient name (Kana)”, “patient name (from the patient information included in the incidental information of the DICOM image data read from the medium M”. "Chinese characters)", "patient gender", "patient birthday". Then, the control unit 31 searches the patient information table T1 of the DICOM image data management DB 352 for a record in which all the extracted items match (step S1).

  As a result of the search in step S1, if the corresponding record exists in the patient information table T1 (step S2; YES), the control unit 31 calculates a matching rate of patient information. And the control part 31 produces | generates the record containing the patient information corresponding to this applicable record, and the calculated coincidence rate, and adds it to patient information extraction list L1 (step S3).

  Here, the “match rate” is a value indicating the degree of match between the patient information included in the incidental information of the DICOM image data read from the medium M and the patient information managed in the patient information table T1. is there. The control unit 31 calculates the “match rate” based on the match rate calculation table T11. The coincidence rate calculation table T11 is stored in the storage unit 35 and developed in the RAM of the control unit 31.

  FIG. 7 shows a data configuration of the coincidence rate calculation table T11. In the match rate calculation table T11, each item is stored in association with the match rate. The control unit 31 sets the value obtained by adding the matching rates associated with the extracted items as the “matching rate” of the record to be added to the patient information extraction list L1. That is, the matching rate associated with each item in the matching rate calculation table T11 indicates the matching weight for each item.

  For example, in step S3, the control unit 31 matches the extracted items “patient name (Roman character)” “patient name (Kana)” “patient name (Kanji)” “patient sex” “patient birthday”. “+ 20%”, “+ 10%”, “+ 40%”, “+ 10%”, and “+ 20%” are added, and the “matching rate” of the record added to the patient information extraction list L1 is set to “100%”.

  Returning to FIG. 6, when the process of step S <b> 3 is completed, or when the corresponding record is not in the patient information table T <b> 1 as a result of the search in step S <b> 1 (step S <b> 2; NO), the control unit 31 reads from the medium M. The items “patient name (Roman character)”, “patient name (Kana)”, “patient name (Kanji)”, and “patient sex” are extracted from the patient information included in the incidental information of the DICOM image data. Then, the control unit 31 acquires records other than the record that matches all the extracted items and is added to the patient information extraction list L1 from the patient information table T1 of the DICOM image data management DB 352. Search is performed (step S4).

  As a result of the search in step S4, when the corresponding record exists in the patient information table T1 (step S5; YES), the control unit 31 calculates a matching rate of patient information. And the control part 31 adds to the patient information extraction list | wrist L1 which produced | generated the record containing the patient information corresponding to this applicable record, and the calculated coincidence rate (step S6). Here, the control unit 31 matches the extracted items “patient name (Roman character)” “patient name (Kana)” “patient name (Kanji)” “patient sex” “+ 20%” “+ 10%” “+40”. % ”And“ + 10% ”are added, and the matching rate of the records to be added to the patient information extraction list L1 is set to“ 80% ”.

  When the process of step S6 is completed or as a result of the search in step S4, if the corresponding record does not exist in the patient information table T1 (step S5; NO), the control unit 31 stores the DICOM image data read from the medium M. The items “patient name (Roman character)”, “patient name (Kana)”, and “patient name (Kanji)” are extracted from the patient information included in the accompanying information. Then, the control unit 31 acquires records other than the record that matches all the extracted items and is added to the patient information extraction list L1 from the patient information table T1 of the DICOM image data management DB 352. Search is performed (step S7).

  As a result of the search in step S7, when the corresponding record exists in the patient information table T1 (step S8; YES), the control unit 31 calculates a matching rate of patient information. And the control part 31 adds to the patient information extraction list | wrist L1 which produced | generated the record containing the patient information corresponding to this applicable record, and the calculated coincidence rate (step S9). Here, the control unit 31 adds the coincidence rates “+ 20%”, “+ 10%”, “+ 40%” corresponding to the extracted items patient name (Roman character), “patient name (Kana)”, and “patient name (Kanji)”. In addition, the matching rate of records to be added to the patient information extraction list L1 is set to “70%”.

  When the process of step S9 is completed or as a result of the search in step S7, if the corresponding record does not exist in the patient information table T1 (step S8; NO), the control unit 31 stores the DICOM image data read from the medium M. The items “patient name (Roman character)” and “patient name (Kana)” are extracted from the patient information included in the incidental information. Then, the control unit 31 acquires records other than the record that matches all the extracted items and is added to the patient information extraction list L1 from the patient information table T1 of the DICOM image data management DB 352. Search is performed (step S10).

  As a result of the search in step S10, when the corresponding record exists in the patient information table T1 (step S11; YES), the control unit 31 calculates a matching rate of patient information. And the control part 31 adds to the patient information extraction list | wrist L1 which produced | generated the record containing the patient information corresponding to this applicable record, and the calculated coincidence rate (step S12). Here, the control unit 31 adds the matching rates “+ 20%” and “+ 10%” corresponding to the extracted items “patient name (Roman character)” and “patient name (kana)” and adds them to the patient information extraction list L1. The record matching rate is set to “30%”.

  When the process of step S12 is completed, or as a result of the search in step S10, if the corresponding record does not exist in the patient information table T1 (step S11; NO), the control unit 31 stores the DICOM image data read from the medium M. The item “patient name (Roman character)” is extracted from the patient information included in the incidental information. Then, the control unit 31 searches the patient information table T1 of the DICOM image data management DB 352 for records other than the record that matches the extracted items and is the source of the record added to the patient information extraction list L1. (Step S13).

  As a result of the search in step S13, when the corresponding record exists in the patient information table T1 (step S14; YES), the control unit 31 calculates a matching rate of patient information. And the control part 31 adds to the patient information extraction list | wrist L1 which produced | generated the record containing the patient information corresponding to this applicable record, and the calculated coincidence rate (step S15). Here, the control unit 31 sets the matching rate “+ 20%” corresponding to the extracted item “patient name (Roman character)” as the matching rate of the record to be added to the patient information extraction list L1.

  When the process of step S15 is completed, or as a result of the search in step S13, if the corresponding record does not exist in the patient information table T1 (step S14; NO), the control unit 31 ends the patient information extraction list generation process.

[Patient information comparison screen]
When the patient information extraction list generation process is completed, the control unit 31 causes the display unit 33 to display a patient information comparison screen 331 including the patient information extraction list L1 in cooperation with the medical image capture program 351.

  FIG. 8 shows a screen example of the patient information comparison screen 331. As shown in FIG. 8, the patient information comparison screen 331 includes patient information included in the patient information extraction list L1 generated in the patient information extraction list generation process and the incidental information of DICOM image data read from the media M. (Media patient information) is displayed.

  Records can be selected in the patient information extraction list L1. The patient information included in the incidental information of the DICOM image data read from the medium M is overwritten with the patient information regarding the record of the selected patient information extraction list L1.

[DICOM image data import processing]
Next, a specific operation of the DICOM image data capturing process performed by the control unit 31 of the PACS 30 in cooperation with the medical image capturing program 351 will be described with reference to FIG.

  The patient information extraction list L1 is displayed on the display unit 33, and an operation signal from the operation unit 32 by a user operation is input, whereby DICOM image data capturing processing is executed.

  As shown in FIG. 9, the control unit 31 determines whether or not there is a record in the patient information extraction list L1 (step S101).

  As a result of the determination, if there is a record (step S101; YES), the control unit 31 selects a record in the patient information extraction list L1 based on the operation signal from the user operation unit 32 (step S102; YES).

  Then, the control unit 31 converts the patient information corresponding to the selected record in the patient information extraction list L1 (the record registered in the patient information table T1) into the patient information of the DICOM image data read from the medium M. Overwriting (reflecting) is performed (step S105).

  Then, the control unit 31 registers the DICOM image data read from the medium M in the DICOM image data management DB 352 and stores it in the storage unit 35 (step S109). Thus, the DICOM image data capturing process is completed.

  On the other hand, as a result of the determination in step S101, if there is no record in the patient information extraction list L1 (step S101; NO), the control unit 31 displays on the display unit 33 that a new patient ID is issued (step S103). Then, the control unit 31 makes an inquiry to the DICOM image data management DB 352 and issues a new patient ID (step S104). Then, the control unit 31 overwrites (reflects) the issued patient ID on the item “patient ID” of the patient information of the DICOM image data read from the medium M.

  In addition, when there is a record in the patient information extraction list L1, a user operation for selecting a record is not performed on the operation unit 32 and a record in the patient information extraction list L1 is not selected (step S102; NO). The control unit 31 displays on the display unit 33 that a new patient ID is issued (step S103), and issues a new patient ID (step S104). Then, the control unit 31 overwrites (reflects) the issued patient ID on the item “patient ID” of the patient information of the DICOM image data read from the medium M.

  And the control part 31 receives the correction of the patient information of the DICOM image data read from the medium M based on the operation signal from the user operation part 32 (step S106; YES). Based on this operation signal, the control unit 31 changes (corrects) the patient information of the DICOM image data read from the medium M (step S107).

  When the processing of step S107 is completed, or when the user operation for correcting the patient information is not performed on the operation unit 32 and the correction of the patient information is not accepted (step S106; NO), the control unit 31 reads from the medium M.
