Multislice 2D (M2D) CINE MRI is a clinical gold standard
for the assessment of ventricular volumes and cardiac
function. However, this acquisition currently needs to
be performed during several breath-holds, leading to
slice-misalignment and long scans duration. In this work
we propose a novel undersampled reconstruction approach
to perform M2D whole heart CINE MRI in a single breath
hold, where each slice is acquired during a single
cardiac cycle. The proposed method, which we call
kt-WiSE, is based on compressed sensing (CS) and a
groupwise temporal registration algorithm for the
estimation and compensation of the motion of the heart.
