Paper Abstract

Digital Subtraction Angiography (DSA) is a medical imaging modality used to study the blood vessels and the cardiac chambers. The primary signal processing goal in DSA is the removal of interfering effects from secondary structures in the image in order to enhance clinically significant details. A combination of various image processing techniques including, image subtractions, contrast enhancements and matched filtering, are currently used in DSA systems. In this paper we mainly investigate the applicability of noncausal zero phase parametric two-dimensional (2-D) modeling to the restoration of angiograms.
