Abstract

This paper describes the use of magnetic resonance imaging to produce quantitative information about heart motion. Motion estimation techniques utilizing convex set projections and simple block shift matching are applied to determine direction and magnitude of heart motion. These methods are tested and compared using simulated motion on a single MRI frame and actual MRI cine data. The simulated motion is in the form of translational only and linear velocity fields. Motion estimation is performed using image pairs with and without additive noise. Results are given which quantify the effectiveness of the algorithms.
