Description

  The present invention relates to a medical information system and a medical image storage device, and in particular, a medical information system that can easily obtain past interpretation reports and case information that are helpful when interpreting medical images and when conferences are performed. And a medical image storage apparatus.

  Conventionally, there is a medical information system in which a medical image storage device that stores medical images and a report creation support device that supports creation of an interpretation report are connected via a network. In addition, some of such medical information systems have a function of providing case information used in conferences (meetings for examining examination results) based on the diagnosis name of the interpretation report.

  In relation to such a medical information system, when a medical image is captured using a medical image diagnostic apparatus, the current imaging condition is often set with reference to imaging conditions in imaging performed in the past. Further, when an interpretation report is created using the interpretation report creation support apparatus, the interpretation report is often created with reference to an interpretation report similar to the current examination result. In many conferences, examination results are often examined by referring to similar case information.

  Therefore, for example, when imaging or interpretation is performed, information that is effective in subsequent imaging or interpretation such as information regarding imaging conditions and key images (images that are particularly important among the captured medical images) is included. A medical information system has been devised in which a shared object included as information is generated and stored so that it can be used for imaging and interpretation performed later (see, for example, Patent Document 1).

  However, the amount of interpretation reports and case information created in the past is usually enormous, and it is very difficult to find interpretation reports and case information that are similar to the results of this examination even if the conventional techniques described above are used. It was difficult. For example, a doctor who is not used to creating interpretation reports, such as a resident, would like to refer to interpretation reports and case information created in the past when creating an interpretation report. In many cases, it took a long time and eventually gave up searching.

  The present invention has been made to solve the above-described problems caused by the prior art, and can easily obtain past interpretation reports and case information for reference when medical images are interpreted or when conferences are performed. An object of the present invention is to provide a medical information system and a medical image storage device capable of performing the above.
