The brain is constantly in motion. Changes in the cardio-ballistic motion of brain structures can provide invaluable information on natural processes and pathology. We have previously introduced a qualitative visualization technique, Amplified MRI (aMRI), to amplify subtle cardio-ballistic motion in the brain. Now we attempt to quantify the underlying motion through simulation-based characterization of the aMRI technique. By generating calibration curves for a range of motion parameters, we calculated the unamplified tissue displacement in two human subjects. The estimated displacements are higher than literature values. Nevertheless, our simulations are the first steps in benchmarking aMRI’s potential as a quantitative technique.
