<P>PROBLEM TO BE SOLVED: To accurately comprehend positional relation between a region of interest and a peripheral region thereof even if the region of interest to a subject is changed while reducing exposure, and further, preventing the increase of an exposure dose and the reduction of workability by the re-imaging of the peripheral region. <P>SOLUTION: This X-ray image diagnostic apparatus 1 includes: an imaging part 3 imaging an X-ray image of a prescribed region of a notice region when obtaining a static image of the notice region, and sequentially imaging an X-ray image of the region of interest inside the prescribed region; an image storage part 5c storing the imaged X-ray image of the prescribed region; an image processing part 5b composing the imaged X-ray image of the region of interest and the X-ray image of the peripheral region except the region of interest in the stored X-ray image of the prescribed region to generate a composite image; and a display part 6 displaying the generated composite image. The image processing part 5b acquires the X-ray image of a change region changed from the region of interest to the peripheral region from the X-ray image of the region of interest before the change according to the change of the region of interest, and superposes it on the X-ray image of the peripheral region to generate the composite image. <P>COPYRIGHT: (C)2013,JPO&INPIT |
