A new framework based on Active Shape Models (ASM) is introduced to correct the motion artifacts induced by respiratory and cardiac motion in myocardial T1 mapping. This framework includes three main steps: training ASM model to capture intensity variations of T1 images at different inversion times, segmentation of T1 weighted images using the trained model, and estimating and applying the registration parameters to correct for motion between images.
