Paper Abstract

A detection-estintation method is introduced for use in digital subtraction angiography (DSA) . The method allows three dimensional (3-D) reconstruction of the vasculature by an image intensifier-based volume irnager using few subtracted projections. In the first step several 2-D projections are processed by vascular segmentation algorithms to define binary vasculature envelopes. In the second step a " logical" backprojection algorithm defines the 3-D binary envelope of the vasculature. The gray levels of the voxels within the 3-D envelope are then estimated by a constrained algebraic reconstruction technique (ART) to refine the vessel boundaries. Results of the reconstruction of an aluminum structure specially designed to test vascular reconstruction algorithms are presented. 1.
