Abstract
Motion artifacts caused by moving anatomy degrade images acquired by means of digital subtraction angiography. It is in principle possible to remove these artifacts through image registration by means of geometrical transformations of properly calibrated images, but there are known difficulties with this approach. In this paper we consider two of these difficulties, the presence of x-ray scatter and, more significantly, the inherent absence of sufficient information to identify correct transformations. We perform experiments using a novel phantom to illustrate these difficulties. The phantom is a balloon that is inflated within the lumen of a coronary artery during percutaneous transluminal angioplasty. We employ two registration techniques, a previously described technique to compensate for gross, simple motion, and a novel one to compensate for smaller, more intricate motion.
