In this work, we developed a new image reconstruction algorithm that enable the possibility to acquire isotropic 3D cardiac cine imaging in a single breath-hold. This technique use the data redundancy to reach acceleration factors up to 13.5 allowing 3D cine acquisition in a single breath-hold. In addition the reconstruction strategy allows for total reconstruction time around 3 mins for a whole 3D data set (2.0x2.0x2.0mm3 isotropic resolution, 16 cardiac phases). In the abstract the acquisition and reconstruction strategy are presented and in-vivo results are shown in pig model.
