Abstract:
1. A method to generate magnetic resonance image data sets using a parallel acquisition technique, comprising the steps of: generating a first echo train after radiating an excitation pulse into an examination subject; said first echo train sufficiently densely scanning a segment of k-space to be scanned for an acquisition of coil calibration data; acquiring said coil calibration data from said first echo train after said excitation pulse; electronically storing the acquired coil calibration data in a coil calibration data set; generating a second echo train after said excitation pulse with no other excitation pulse intervening between said excitation pulse and said second echo train, said second echo train undersampling, according to the Nyquist theorem, a segment of k-space to be scanned for an acquisition of image data; acquiring said image data from said second echo train after said excitation pulse; electronically storing the acquired image data in an incomplete image data set, in which data are missing due to said undersampling; and reconstructing data, as reconstructed data, using a selected parallel acquisition reconstruction technique and using said coil calibration data, and generating a complete image data set by substituting said reconstructed data for said data that are missing in the incomplete image data set due to the undersampling.
