Abstract
The invention relates to a method which enables distributed or dilute structures, for example a vascular system filled with a contrast medium, to be reproduced in a synthetic projection image which reproduces the parts of the vascular system which are situated in a selectable sub-volume more clearly than the X-ray images, formed from different perspectives, wherefrom the projection image is derived. The voxel image values associated with the voxels of the sub-volume are first determined and from these voxel image values there is calculated a synthetic projection image in which the selected sub-volume is reproduced.
