Recent literature has shown the potential of high‐resolution quantitative susceptibility mapping (QSM) with ultra‐high field (7T) MRI for investigating the magnetostatic properties of brain structures and disease pathology. Higher spatial resolutions, however, require longer scans resulting in a higher likelihood of subject movement. Here, we apply a novel prospective real-time optical motion tracking and correction system using a camera integrated between the Tx and Rx coils of a commercial 7T head coil to demonstrate the feasibility of acquiring high-resolution R2* and QSM images robust to subject motion.
