Abstract

The coded aperture imaging technique using an array of x-ray sources for display of three-dimensional is applied to a relevant medical object: the coronal vascular system of an isolated heart filled with contrast medium, coded according to a nonredundant point distribution. Arbitrary layers of the heart are decoded by correlation using a holographic system. The course of the vessels in the third dimension can clearly be followed, thus presenting a completely novel tool of medical diagnosis.
