Abstract
Described here are systems and methods for estimating bulk rotation and translation of an imaged subject between different blades in a PROPELLER MRI or similar sequence. Correlations between unique pairs of blades are calculated and the relative shift values that maximize the correlation between each pair of blades are identified as relative shift values to be applied for motion correction. Using this method, no reference blade is required, nor does a computationally expensive iterative process need to be performed.
