Abstract :
In this work we present a motion analysis for cardiac-gated tagged MRI data of the left ventricle (LV) of the heart. The dense field motion analysis is based on a deformable mesh model (DMM) that incorporates a heart surface model. The motion field is derived using intensity based image matching. DMM is well suited for motion tracking and analysis of organs undergoing non-rigid deformation. Previously, we successfully utilized DMM for heart motion tracking in cardiac SPECT image reconstruction. Preliminary results presented here for tagged MRI demonstrate further potential of this approach.
