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.
