摘要
Angiography system for angiographic examination of an organ, vascular system or other body regions as examination subject of a patient (6) with an X-ray source (3) and an X-ray image detector (4), which are attached to the ends of a C-arm (2), a patient table with a table top (5) for the storage of the patient (6), a system control unit (7), an image system (8) and a monitor (9), characterized in that the X-ray image detector (4) is a counting energy-resolving X-ray image detector (4) formed in such a way in that it detects the number of incident X-ray quanta and their spectral energy for taking up (11) an X-ray image for each pixel, and in the system control unit (7) is provided a device (10) for storing and weighting the stored energy information is designed such that it calculates intensity gray values of an X-ray image, the de m of an integrating detector, and converts the spectral information of the X-ray image detector (4) into spectral gray values, wherein the gray values are reproduced on the monitor (9).
