<P>PROBLEM TO BE SOLVED: To provide an X-ray diagnosing apparatus capable of obtaining a clear subtract image or a good long combined image without a manual system. <P>SOLUTION: A system controller 7f acquires the detailed position information of a holder 3 and a bed 5 under photographing every frame from a holder/bed position detector 6, makes the position information incident to a frame memory for image data taken at the position thereof, and stores the information in an image memory 7b. For subtraction from image data stored in the image memory 7b or for making a combined long image, an arithmetic processor 7c calculates the position deviation of its mechanism system (the holder 3 and the bed 5) from the position information incident to the frame memory of each image data, converts it to a pixel shift quantity, and executes a pixel shift step based on the pixel shift quantity. <P>COPYRIGHT: (C)2003,JPO |
