Patent ID: 8320646

Claim:
A method for producing an image with a magnetic resonance imaging (MRI) system, the steps comprising: a) directing the MRI system to acquire NMR signals by sampling three-dimensional k-space at a plurality of points arranged on a grid of sample points, wherein all of the plurality of points on the grid of sample points within a central region of the three-dimensional k-space are all sampled and only selective ones of the plurality of points on the grid of samples points outside the central region and within a peripheral region of k-space are sampled as a set of radial sectors that are asymmetrical about an origin of a plane in k-space and outside the central region and do not extend into the central region; b) acquiring the NMR signals with a plurality of separate coils and receive channels to produce corresponding separate k-space image data sets; c) performing a homodyne high pass filtering operation on each of the k-space image data sets; d) reconstructing an image from each of the high pass filtered k-space image data sets; e) producing a high pass image (I H ) by combining the images produced in step d); f) performing a low pass filtering operation on each of the k-space image data sets; g) reconstructing another image from each of the low pass filtered k-space image data sets; h) producing a low pass image (I L ) by combining the images produced in step g); and i) producing an image by correcting the phase of the high pass image (I H ).
