The accuracy to compensate or correct for MR image artifacts from motion depends on the ability to precisely measure patient motion. Optical cameras are a compelling solution as they simplify patient setup and do not negatively impact MR data acquisition. However, most efforts have been focused on integrating and applying optical cameras to neuroimaging. In this work, setup and methods for video processing were developed for lung and abdominal MRI where MRI acquisition is especially sensitive to motion. The proposed solution had high correlation with conventional approaches of respiratory bellows and MRI navigators; also, comparable image quality was achieved.
