Method and system for motion correction of magnetic resonance images

A system for processing acquired magnetic resonance MR images, the system comprising:

• a processor;
• and
• a memory comprising instructions configured to cause the processor to:
• obtain a first series of MR image frames of a patient's anatomy over a first time period and a first quantitative parameter map based on the first series of MR image frames;
• obtain a second series of MR image frames of the patient's anatomy over a second time period and a second quantitative parameter map based on the second series of MR image frames;
• wherein the first time period does not overlap with the second time period;
• select at least one MR image frame from the first series of MR image frames as a first representative image;
• select at least one MR image frame from the second series of MR image frames as a second representative image;
• calculate a misalignment valuation based on a comparison of the first representative image to the second representative image;
• and
• compare the first quantitative parameter map and the second quantitative map based on the misalignment valuation to generate a comparison map.
