Highly Accelerated Free-breathing 4D Cardiac Imaging with CIRCUS Acquisition

An effective k-space undersampling scheme (CIRCUS) for 3D Cartesian imaging with compressed sensing and parallel imaging has successfully been implemented and applied to free-breathing 4D cardiac imaging. Our preliminary results demonstrated the nice features and great potentials of the proposed acceleration method. We showed promising whole heart CINE images achieved in 2 minute scan time.
