Abstract

Magnetic Resonance Imaging has become popular over the last few years as a technique for non-invasively imaging the internal structures of live subjects. In this paper we describe a technique to assist in the analysis of this type of data. We use quadratic B-splines and dynamic contours to track tagged regions of an infused rat heart, and analyse the motion of the tagged regions in terms of various predefined characteristic motions.
