ABSTRACT:
The subject invention pertains to a method for acquiring and reconstructing a collection of time crucial magnetic resonance images. The subject invention is applicable for speeding up acquisition of or improving the quality of the set of images. In one specific embodiment, the subject method is used to reduce the time required to generate a cardiac CINE sequence of phases of the heart.
