ABSTRACT:
An MRI system employs a multicoil array to acquire NMR data. A calibration scan is performed and a phase map is produced for each coil element in the array. A region of interest in the field of view is identified and corresponding phase values are extracted from each phase map and used to correct the phase of the k-space NMR data set acquired by each coil element in subsequent image scans. The corrected k-space NMR data sets for the coil elements are combined into a single k-space NMR data set to enable an image to be reconstructed therefrom by Fourier transformation.
