We developed a pixel tracking motion compensation reconstruction framework for 3D acquisitions. The method was compared to a rigid motion compensation reconstruction method and to reconstruction without motion compensation using a cardiac perfusion dataset acquired with a 3D stack-of-stars sequence. The pixel tracking motion compensation method improved reconstruction, while the rigid motion compensation led to blurring.
