Abstract

MRI METHOD USING PRISM ACQUISITION WITH MOTION CORRECTION FOR FINE STRUCTURE DATA ANALYSIS A method of improving the data quality in spatial frequency spectra by acquiring a prism acquisition consisting of echo data that is one or more repetitions of a one- dimensional frequency encoded signal along the length of one or more prism volumes, placed within a sample of a structure to be studied, generating prism profiles from the echo data, and correcting for motion during the acquisition by calculating motion having occurred during the prism acquisition from assessment of the prism profiles for the multiple repetitions, or by indicating a region of sample of structure to be studied on a reference image, using this to segment a map of features in the prism profiles and shifting the location of this region to correct for motion having occurred between the acquisition of the reference image and the prism acquisition.
