Cardiac motion estimation from MR image sequences

Research output: Contribution to journalConference article

Abstract

A method to reconstruct motion using magnetic resonance (MR) imaging is presented. Magnetic resonance imaging tagging is used to create intensity gradients within objects, where the intensity would otherwise be largely constant. Since the tag field decays with T1, a modified optical flow algorithm is developed and implemented. Object parameters T1, T 2, and D0 are required to be known across the image at the time the tag field is created; motion is then determined by computing optical flow between pairs of images and estimating the implied motion reference map at each pixel site.
