FORMING AN ASSEMBLED IMAGE FROM SUCCESSIVE X-RAY IMAGES

摘要

A method for forming an assembled image from successive sub-images comprises the step of acquiring the sub-images, notably X-ray images, with an X-ray detector comprising an essentially flat X-ray-sensitive surface. An X-ray examination apparatus comprises an X-ray detector having a flat X-ray sensitive surface. Advantageously, difference images are derived from successive sub-images. For example, the assembled image derived from the difference images is used to display blood flow patterns in a patient's vascular system.
