Patent ID: 8306299

Claim:
A method for reconstructing a motion-compensated image depicting a subject with a magnetic resonance imaging (MRI) system, the steps of the method comprising: a) acquiring with the MRI system, a time series of k-space data sets by sampling k-space along non-Cartesian trajectories at a plurality of time frames; b) identifying in the time series of k-space data sets acquired in step a), ones of the plurality of time frames at which motion occurred; c) segmenting the time series of k-space data acquired in step a) to produce a plurality of k-space data subsets, each k-space data subsets containing k-space data acquired in temporally adjacent time frames occurring between the ones of the plurality of times frames at which motion occurred identified in step b); d) determining motion correction parameters from the k-space data subsets produced in step c); e) producing corrected k-space data subsets by applying the motion correction parameters determined in step d) to the k-space data subsets produced in step c); f) combining the corrected k-space data subsets produced in step e) to produce a corrected k-space data set; and g) reconstructing a motion-compensated image from the corrected k-space data set produced in step f).
