The advancements in signal to noise ratio (SNR), contrast, and resolution enabled by high-field MR systems may visualize more nuanced brain anatomy and pathology. In order to translate these advancements to the discovery and clinical implementation of novel neuroimaging biomarkers, motion artifact resulting from requisite long scan times must be addressed. Here, we demonstrate a novel prospective optical motion tracking and correction system using a camera seamlessly integrated into the 7T Tx/Rx head coil. The integrated camera allows tracking of head motion by visualizing an optical marker on the forehead of human subjects in a 7T MR system.
