Patent ID: 7005853

Claim:
A magnetic resonance imaging method to produce successive magnetic resonance images of a region of a static subject, the magnetic resonance imaging method comprising: acquiring temporally successive sets of magnetic resonance signals from the region of the subject, wherein the region contains a moving subregion of the subject, by successively scanning the region to produce respective sparsely sampled sets of data points in k-space such that (i) the successive scanning builds up a sampling density of k-space and (ii) the successive scanning of the region covers more frequently a predetermined portion of k-space such that the predetermined portion is fully sampled; determining a static MR image directly from the acquired temporally successive sets of magnetic resonance signals; and reconstructing temporally successive magnetic resonance images from a combination of the successive sets of magnetic resonance signals, the static MR image, and a spatial distribution of a likelihood of changes in the successively reconstructed magnetic resonance images.
