ARI - A STORAGE RING FOR NON-INVASIVE CORONARY ANGIOGRAPHY

One of the standard investigations for coronary heart diseases is the invasive coronary angiography, where a catheter is introduced via the arterial system into the origin of the coronary artery of interest. By using high intensity X-ray beams just above and below the K-edge of iodine, the contrast agent, and digital subtraction of the two pictures one can often avoid the use of a catheter and the risks of the conventional method. A 1.6 GeV electron storage ring is described, which is designed as a source for two coronary angiography beamlines. The necessary photon intensity at the K-edge of iodine (33 keV) is provided by two 6 Tesla wigglers and 380 mA beam current intensity.
