Description

[Detailed description of the invention] [Technical field of invention] The present invention is applicable to, for example, nuclear medicine equipment, ultrafa [diagnostic equipment].

This invention relates to a medical RA escape device that processes and displays various medical images of the same region obtained from an X@CT, X-ray film diagnostic device, or the like.

[Technical background of the invention and electric point between them]

Conventionally, when a target part of a subject is to be diagnosed by #I, for example, nuclear medicine equipment or ultra-tyL diagnostic equipment is used.

Various medical diagnostic devices such as X@CT device and X@film diagnostic device are used and their functions! They are used depending on the IC. For example, when diagnosing the same part of a subject using various medical diagnostic devices such as those mentioned above, there may be cases where parts that are not clear with one device become clear with the other device due to differences in the functions of each device, or The opposite case occurs. Therefore, if, for example, two types of l1lifl data can be superimposed, each distinct part of the data can be extracted and displayed as a single liis, the diagnostic ability can be improved. However, the n#i home data obtained from various medical diagnostic devices is
