Keywords: Image acquisition: Motion correction, Cardiovascular: Cardiac, Image acquisition: Reconstruction
This tutorial will focus on how to implement a framework for retrospective respiratory motion correction in practice. We will focus on whole-heart cardiac MRI and will review the steps required to produce motion compensated images, including key components in the image acquisition sequence to enable measuring respiratory motion directly, alternatives for estimating rigid and non-rigid motion, and ways of including motion information in the image reconstruction process. The talk will demonstrate some challenging cases and the impact of choosing rigid/non-rigid respiratory motion models for a variety of whole-heart applications.
