Abstract

In this work, we propose a novel approach for the reconstruction of 3D isotropic, free-breathing cardiac cine MRI with 100% data efficiency. The main components are a continuous 3D Golden radial k-space data acquisition, a robust groupwise cardio-respiratory motion estimation technique and a multiresolution strategy introduced in a previously proposed compressed sensing reconstruction scheme. Initial results on simulated data show better reconstruction quality than the non-motion compensated counterpart and reduced reconstruction times with respect to a single-resolution procedure for equivalent acceleration factors ranging 24.38 to 34.8.
