A MRI METHOD OF FASTER CHANNEL BY CHANNEL RECONSTRUCTION WITHOUT IMAGE DEGRADATION

摘要

A plurality of coil elements (18 18 ) and corresponding receivers (26) define a plurality of channels each carrying a corresponding partial k space data set (60 64). One or more processors (30) generate (80) a first image representation (76) based on the plurality of partial k space data sets generate a relative sensitivity map (82) for each of the channels project (90) the first image representation (76) with each of the relative sensitivity maps (82) to generate a plurality of recreated k space data sets (92) and each partial k space data and the corresponding recreated k space data set are combined to generate substituted k space data sets (96). The substituted k space data sets are reconstructed (100) into a plurality of images (102) which are combined (104) to create a final image (106).
