Abstract:
1. A method for obtaining an image of an interconnected region of a subject by partially parallel acquisition magnetic resonance imaging, comprising the steps of: (a) exciting precessing nuclear spins in a region of a subject; (b) simultaneously obtaining a plurality of response signals, representing nuclear magnetic resonance signals arising from said precessing nuclear spins, from said region respectively with a plurality of RF reception coils, with each response signal representing a reduced k-space dataset of a totality of all of said response signals; (c) additionally obtaining calibration data points for each dataset; (d) for each of said RF reception coils, forming a complete k-space dataset in k-space from the reduced k-space dataset from step (c) for that RF reception coil and the reduced k-space dataset from step (c) of at least one other of said RF reception coils; and (e) for each of said RF reception coils, spatially transforming the complete image dataset obtained in step (d) to obtain a complete image of said region, and thereby obtaining a plurality of complete images of said region.
