The physical patterns ruling the information of a xeroradiographic image allow the visualization of the arterial system with a lower concentration of contrast medium. So you can visualize the arterial branches both with intravenous injection of the usual angiographic concentration of contrast medium or with intraarterial injection of diluted contrast medium at a very low concentration. A prerequisite to successful xeroangiography was the commercial diffusion of a changer for xerox cassettes allowing several exposures according to standardized programs.
