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 a first 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 first excitation pulse; electronically storing the acquired coil calibration data in a coil calibration data set; generating a second echo train after a second excitation pulse, said second echo train undersampling 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 second excitation pulse; electronically storing the acquired image data in an incomplete image data set; generating an image data set by substituting data that are missing in the incomplete image data set due to the undersampling, using a selected parallel acquisition reconstruction technique using said coil calibration data; and generating said first echo train and said second echo train with an identical sequence technique such that each of said first and second echo trains to be comprised of a series of echoes, with a time interval between successive echoes of the first echo train being shorter than a time interval between successive echoes of the second echo train.
