2. Description of the Related Art Conventionally, a photographed film of an affected area, which is represented by an X-ray photography film, has been widely used as a device capable of visually displaying the progress of treatment of a patient. However, with the large number of patients who are generally treated in hospitals,
Since the affected area is photographed to a certain extent on a regular basis as the treatment is continued for one patient, the number of photographed films is significantly increased, which requires not only a huge storage space but also a desired storage area. The time required to search for a film that has already been shot becomes extremely long.

In consideration of this point, medical image data obtained based on a photographed film or the like is stored in an optical disk, a keyword is input by operating the keyboard of the input device, and the keyword is applied based on the input keyword. Medical image file system that reads out and visually displays medical image data ("medical image filing practice", video information (I), Minashige Nagai, February 1993), and medical image and its attribute information are accumulated and recorded. Then, in response to the input of the search condition, the medical images are searched based on the search condition, all the searched medical images are displayed on one screen, and a plurality of medical images are searched based on the new attribute information. There has been proposed a medical image file device (see Japanese Patent Laid-Open No. 62-74155) in which a desired medical image is selected from images.

In the former medical image file system, a desired medical image can be visually displayed by inputting a keyword. Further, in the latter medical image file device, a desired medical image is displayed by selecting a desired medical image based on new attribute information from a plurality of medical images searched based on the search condition. Can be achieved. Then, in any case, the doctor explains the treatment progress to the patient in a state in which the desired medical image is visually displayed,
The doctor can give a sufficient explanation in a short time, the patient can fully understand the explanation of the doctor, and effects such as an increase in the confidence of the doctor can be achieved.

[0005]

However, in the case of adopting the former medical image filing system, it is indispensable to input a keyword accurately in order to select a desired medical image. Therefore, it is necessary to learn the operation of the system. Moreover, a person who does not have sufficient knowledge for treating a patient cannot easily select a desired medical image. In addition, in general, one doctor treats a large number of patients, and since the treatment for a patient who needs an explanation of the course of treatment takes a long time, in order to achieve accurate keyword input, a medical record etc. It becomes necessary to input the keyword by seeing, and the keyword input becomes extremely complicated. In particular, when the date of treatment is used as a keyword, it is necessary to check the corresponding date to check the corresponding date before inputting the keyword, which makes the work for inputting the keyword complicated.

When the latter medical image filing apparatus is adopted, a plurality of medical images are selected by inputting attribute information that is not set in detail so that a desired medical image can be specified. Since it can be displayed on the screen, the workability for inputting the attribute information can be considerably improved, but since each medical image becomes smaller, the resolution inevitably lowers,
For example, it becomes extremely difficult to select a desired medical image from a plurality of medical images showing the transition of the therapeutic effect, and in the worst case, it becomes impossible at all. In an extreme case, all of the medical images displayed on one screen may be the same in appearance, and it may be meaningless to display the medical images on one screen. . Then, in such a case, it becomes necessary to input the keyword as complicated as the former case.
