Motion artifacts continue to be a significant problem in MRI of human brain. Prospective motion correction based on external tracking systems has been proposed to ameliorate this issue. However, the calibration of these systems is very complicated and time consuming, as it requires a camera system calibration as well as a calibration between camera and MRI system using dedicated phantoms. An alternative motion correction method for MRI that does not require calibration and can work with just a single video camera has been developed and is available for licensing. This technology can be broadly applied in MRI to account for motion artifacts in order to improve acquisition time and provide enhanced resolution. This technique will provide a needed method to obtain reliable MRI scans for uncooperative patients (children, seizure patients, etc.) without the need and expense of multiple scans.
