Magnetic resonance tomography (MRT) imaging based on partially parallel acquisition (PPA) reconstruction method for use in medical field, by processing data records using reduction matrix and reconstruction matrix to form graphic data set
The method involves acquiring high-frequency (HF) response signals from several component reels to form an incomplete data record with calibration data points. The incomplete data records are reduced into a subset of reduced incomplete data records based on an N by M reduction matrix, where N and M are of predetermined values. Complete data records are formed based on an N by M reconstruction matrix using the reduced incomplete data records and the incomplete data records. The complete data records goes through spatial transformation to form a complete graphic data set. Independent claims are included for the following: (1) MRT imaging device; and (2) Computer software product storing the program for MRT imaging.
