1. A method comprising:
accessing a set of imaging data including first imaging data for a first time point, second imaging data for a second time point, and third imaging data for a third time point;
identifying a first location of a region of interest (ROI) in the first imaging data;
identifying a second location of the ROI in the second imaging data;
identifying a third location of the ROI in the third imaging data;
determining a plurality of differences between the identified locations, wherein the plurality of differences include a difference between:
the first location and the second location;
the first location and the third location; and
the second location and the third location;
based on the determined plurality of differences, selecting one of the first imaging data, the second imaging data, or the third imaging data as reference imaging data for motion correction; and
performing motion correction for the set of imaging data with the selected reference imaging data.
