Computer simulation of blood vessel images is described to study the effects of technical factors on observers' performance in detecting small details in angiographic images. The blood vessel images generated by a computer are embedded in radiographic noise of a given screen-film combination which was digitized at high resolution. The final images, which appear on film, are organized to permit the estimation of Receiver Operating Characteristic curves for detecting vessels and their correct location.
