DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to refer to medical images .
Medical image display system .

[0002]

2. Description of the Related Art When a doctor is reading images on a reading workstation 2 of a conventional medical image storage communication system as shown in FIG. In some cases, there may be cases where the diagnosis is lost. For example, it may be necessary to refer to an image of a similar case in the past because he / she is confused that he / she may have a stomach cancer but may have a stomach ulcer. Thus, for example, a case in which a gastric cancer was diagnosed in the past by a radiology department but a gastric ulcer was found in a definitive examination (diagnostic discrepancy) would be searched.

The search directory of the image database of the conventional system as described above is configured to search for a target image by patient number / examination number as shown in FIG. Therefore, in order to search for a diagnostic discrepancy, a patient who had a past diagnostic discrepancy was searched in the medical chart, and the examination number / patient number was input on the workstation 2. Also, when searching past examples by relying on memory, it was necessary to memorize examination numbers and patient numbers.

[0004]

When searching for an image of a target diagnosis discrepancy relying on memory, a workstation using an examination number / patient number as a search command is used.
It is impossible to remember these numbers. Also,
Even if an attempt is made to check the number on a medical record, the number of past tests is enormous, and it takes time and effort to individually check the number. Furthermore, since the target diagnosis discrepancies are arranged in various places, there is a disadvantage that not only searching for one sheet but also searching for a plurality of sheets requires more time and effort, and the searching range is limited. there were.

[0005] In order to solve the above-mentioned inconvenience, the present invention provides a medical image display for displaying an image of a reference case (example of discrepancy diagnosis) required on a terminal by a simple designation from the terminal.
The purpose is to provide a system .

[0006]

In order to achieve the above object, a medical image display system according to the present invention comprises a plurality of medical image display systems for each examination.

[0009]

FIG. 1 conceptually shows a configuration example of a medical image communication system using a reference case search method according to the present invention. An editing workstation 1, an interpretation workstation 2, an image database 5 and a reference case database 6 are used. Is shown. In this configuration example, one interpretation workstation is used for explanation, but the present invention can be similarly applied to a plurality of workstations.

First, a method of storing reference cases (diagnosed cases) in the reference case database 6 will be described. Radiology readings, conferences,
The requested department is interpreted, and the image finally finalized is stored in the image database 5. The format of the test when stored is as shown in FIG.
1, examination information such as patient information 32, chart information 33,
The report 34 has diagnosis history information 35 in addition to images. The diagnosis history information 35 records the interpretation result A of the radiology department, the diagnosis result B of the request department, the diagnosis result C of the CAD, and the final definitive diagnosis. Then, before the format of the examination shown in FIG. 3 is stored in the image database 5 of FIG. 1 via the case identification means 42 shown in FIG. 4, diagnosis of each department of the diagnosis history information 35 of FIG. C
Diagnosis result of AD and diagnosis result of definite diagnosis A, B,
Whether or not there is a discrepancy between C and D is determined by the diagnosis history comparing means 5.
2 are compared. The diagnostic results A, B, C,
D is a disease name such as stomach cancer or stomach ulcer and is usually coded, so that comparison is easy. Diagnosis results A, B,
When C and d are both equal, there is no discrepancy in the diagnostic results. If any one of the diagnostic results A, B, C, and D is different from the others, there is a discrepancy in the diagnostic results.

FIG. 2 shows a reference case directory 21 as reference case information according to the present invention. The reference case directory contains the storage address of certain interpretation images, each examination fee, and C
AD and the discrepancy case of the test result in the definitive diagnosis are associated and combined. For example, in FIG. 2, the image at the image storage address 4000 is diagnosed as gastric cancer in the radiology department and the request department as a result of interpretation, but is diagnosed as a gastric ulcer by CAD diagnosis, and as a gastric ulcer in the final diagnosis (confirmed diagnosis). This is a reference case (misdiagnosis). The image case directory 21 stores such a diagnosis discrepancy (or misdiagnosis).
Of the reference case identification means 40 shown in FIG.
In the above, the reference case comparison means 45 creates and adds the information after the check by the diagnosis history comparison means 43. FIG. 4 shows the configuration of the reference case identification means 40, and FIG. 5 shows the operation of the reference case identification means 40.

As described above, in this embodiment, FIG.
Before being stored in the image database 5 of FIG. 1 through the test data in the format shown in FIG. First, the test received by the receiving means 41 in response to the test definite diagnosis notification shown in step 51 of FIG. 5 is compared with the diagnostic history 35 shown in FIG. 3 by the diagnostic history comparing means 42 (step 52). If the comparison results are equal (there is no diagnosis difference), the inspection data is stored in the image database by the storage unit 48 via the driving unit 43 (step 56). If the comparison results are not equal (there is a diagnosis discrepancy), the examination data is transferred to the reference case database 6 by the transmission means via the driving means 43 (step 54).
Then, a reference case directory is created by the reference case directory creation means 45, and the sent cases are stored.

In the embodiment, the image database 5 and the reference case database are physically different, but the storage area may be different on the same database, or the image database may have a reference case directory. Is also good. In the embodiment, the reference case directory is created by the reference case identification unit before storing the examination data. However, the reference case directory may be created by the reference case identification unit after the examination data is stored.

Next, how a doctor uses this system will be described. The doctor interprets the medical image on the interpretation workstation and writes a report. In addition, a conference is prepared (edited) by rearranging medical images and viewing references on the editing workstation. Difficult cases may appear during these tasks. For example, you may have a hesitation that you think you have a stomach cancer but may have a stomach ulcer. Then, in the past cases, for example, a stomach cancer was diagnosed in the radiology department, but in a definitive examination, it is desirable to refer to a case that had a gastric ulcer (reference case).

Then, the doctor uses the case designating means 61 on the workstation shown in FIG. 6A to designate a reference case to be viewed. The designation method is as follows. A disease name is selected from the disease name list in FIG. 6B with a mouse or a light pen, and the selected disease name is input to the radiation field of the input means 61. If the user wants to enter a disease name in the other input fields (request department, CAD, definitive diagnosis field), he or she inputs it in the same manner.
Alternatively, the search command may be set to a default (in the case of the default, a disease name other than the disease name input in the field of radiology is used as a default value as a search command). Finally, when the input end button 62 is pressed, the input reference case identification information becomes a search command (this flow is shown in the flowchart of FIG. 7).

When the input end button is pressed, a search command is sent to the reference case database 6 via the LAN.
Since the reference case database has the reference case directory shown in FIG. 2, the image stored at the address indicated by this directory is sent to the interpretation workstation 2 and the editing workstation 1. The doctor interprets the images while viewing the reference cases sent, and adds them to the images used for the conference. In the embodiment, the case designating means is an input designation field provided on the workstation as shown in FIG. 6A, and is designated and inputted from a list of disease names provided on the same workstation as shown in FIG. 6B. However, the method of designating a case at the workstation is not limited to this, and may be a known method that allows a doctor to designate a case to be viewed.

[0017]

According to the present invention, when a patient who is lost in diagnosis during the reading of medical images or editing materials for conference preparation can easily refer to similar cases in the past as reference cases. Therefore, it is possible to reduce the time required for image interpretation and the time required for editing conference preparation. In addition, diagnostic accuracy can be improved, erroneous diagnosis can be prevented, and diagnostic capability can be improved.
