We combine the Variable density Incoherent
Spatio-Temporal Acquisition (VISTA) sampling pattern
with a Fast Iterative Shrinkage Thresholding Algorithm
(FISTA) implementation of SENSE to achieve online
real-time, free-breathing cardiac cine imaging with < 40
ms temporal resolution and < 2x2 mm2 in-plane spatial
resolution with low latency (< 10 second) reconstruction
time. We test our method in five healthy volunteers and
demonstrate diagnostically sufficient image quality
compared to conventional segmented techniques with no
significant difference in measurement of volumetric
parameters.
