Description

  The present invention relates to an interpretation report used by an interpretation doctor to create an interpretation report in an interpretation support system for assisting an interpretation performed by a doctor after taking an examination image (medical image) used for medical diagnosis based on an image. It relates to a creation device. Furthermore, the present invention relates to a client terminal used by a client such as a clinician who has requested interpretation in a browsing system for browsing an interpretation report.

  In recent years, medical imaging acquired by examinations with the spread of medical digital image generation technologies such as CR (computed radiography), MRI (magnetic resonance imaging), CT (computed tomography), etc. Management of images electronically is performed.

  In general, when an imaging examination is performed, the medical doctor interprets the captured medical image before a specific diagnosis is made by the attending physician, and the interpretation results and findings are entered. An interpreted interpretation report is created. Conventionally, even when digital image data is generated, medical images hard-copyed on photographic film have been used for interpretation, but with the development of high-definition image monitors (viewers), the monitor Interpreting the medical image displayed above is also performed.

  Also, an interpretation report is electronically created using an interpretation report creation apparatus. In that case, it is common to attach a key image to an interpretation report. Here, the key image is an image determined by the interpretation doctor as a key for interpretation among a series of images obtained by one examination, and at least one image is included in one examination. Set as key image.

  Thereby, the doctor in charge (requester) who requested the interpretation doctor to interpret the examination image can observe the key image attached to the interpretation report when browsing the interpretation report created by the interpretation doctor. . However, if it is necessary to observe the examination image in more detail in order to understand the contents of the interpretation report, it is desirable to reproduce the image display state of the examination image observed when the interpretation doctor creates the interpretation report. It is. Therefore, it is convenient if the client can easily obtain the examination image displayed on the viewer when the interpretation doctor attaches the key image to the interpretation report, and the client can view and confirm it in the same image display state. It is.

  As a related technology, Patent Document 1 interactively operates two-dimensional, three-dimensional, and four-dimensional images related to an image diagnosis report in a user terminal device connected to a medium / low speed network. A report creation / browsing system that can acquire information interactively is disclosed. In this report creation / viewing system, a data processing device is installed in the vicinity of the network of the PACS server that stores and transfers medical image data, and the reference image reproduction and related information are included in the image diagnosis report created by the image diagnostician. An image processing parameter set for acquisition is attached. The user of the requesting department obtains image data and related information from the PACS server etc. by sending the parameter set attached to the image diagnosis report to the data processing device when browsing the report on the user terminal it can.

  According to Patent Document 1, the client can know what kind of image processing has been performed on a medical image corresponding to a certain interpretation report. However, when the interpretation doctor creates an interpretation report, the client image can be obtained. It is impossible to know the image display state of what is observed and displayed at what layout and enlargement ratio.

  Further, Patent Document 2 includes an image display device that displays a medical image, an image archive device that stores image data that carries the medical image in a storage medium, and reads out from the storage medium, and a manual operation unit. An interpretation report system comprising means for performing a predetermined process on a medical image displayed on the image display device based on an operation performed by the manual operation unit is disclosed. In this interpretation report system, an interpretation report means for creating an interpretation report relating to an image displayed on the image display apparatus, an interpretation report display means for displaying the interpretation report, and image data stored in the image archive apparatus. A control unit that stores information indicating an operation performed by the manual operation unit when an image based on the image display device is displayed on the image display device in association with the image data and the interpretation report on the image in a storage unit. Is provided.

In Patent Document 2, a link for reading out image data stored in the storage means in association with the interpretation report is formed in the interpretation report. Therefore, the image data of the inspection image used for interpretation Even if not all are stored, the inspection image corresponding to the interpretation report can be reproduced. However, when a plurality of key images are attached to an interpretation report, there is a problem that the image display state of the plurality of key images cannot be managed.
