IPC: A61B6/00
Filed: 2001-07-23
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray fluoroscopy photographing apparatus that can precisely learn a change of photographed regions of a subject to the examined with the lapse of time. SOLUTION: Since the apparatus is equipped with a difference detector 17 which detects a difference between a first time point and a second time point images of the same photographed region Ma obtained by a same photographed condition by the signal processing of an image signal of both images and a difference display 18 which displays a difference between the detected images in the first time point image or the second time point image, there is no concern that the difference between the images is left unnoticed.  In addition, because an X-ray detector is made as a flat-panel type X-ray detector 2, there is no such distortion that is difficult to correct in the first and the second time point images to be compared, and the difference between the images correctly corresponds to a change in the photographed region Ma, thus making it possible to precisely learn a change in the photographed region Ma of the subject M with the lapse of time.
