Abstract

Disclosed herein is a medical system (). The execution of machine executable instructions () causes a processor () to: receive () measured gradient echo k-space data (); receive () an off-resonance phase map (); reconstruct () an initial image () from the measured gradient echo k-space data; calculate () an upsampled phase map () from the off-resonance phase map; calculate () an upsampled image () from the initial image; calculating () a modulated image () by modulating the upsampled image with the upsampled phase map; calculate () a corrected image () comprising iteratively. The iterative calculation comprises: calculating () updated k-space data by applying a data consistency algorithm () to a k-space representation of the modulated image and the measured gradient echo k-space data and calculating () an updated image () from the updated k-space data. Calculation of the updated image comprises demodulation by the upsampled phase map and applying a smoothing algorithm.
