Using Wave-CAIPI-like techniques to accelerate Balanced Steady-state Free Precession (bSSFP) sequences is a new parallel imaging technique that reduces the noise levels on the reconstructed image compared to conventional parallel imaging. On the heart, this combination of sequence has not been tested. The experiments show that the movements of the thorax are not an issue, as long as a respiratory and ECG triggering are employed. A retrospective acceleration of 5.4 on a sheep heart image with a 1.4mm isotropic resolution has been achieved.
