<p><P>PROBLEM TO BE SOLVED: To provide a digital subtraction apparatus capable of appropriately obtaining the subtraction image of an image pickup part of a subject. <P>SOLUTION: An X-ray fluoroscopic apparatus 2 comprises a differential arithmetic coefficient adjusting part 8. In the case of subtraction by a computing element 34, the differential arithmetic coefficient adjusting part 8 adjusts a differential arithmetic coefficient to perform weighting on each image on the basis of displayed results of a basic image (mask image) and a high frequency component eliminated image (live image) on a monitor 4, so that the subtraction image of the image pickup part of the subject can be appropriately obtained by weighting. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
