Automatic motion correction of Musculoskeletal MRI using DSLR camera

The purpose of this study is to illustrate motion correction in Musculoskeletal (MSK) Magnetic Resonance Imaging (MRI) through utilization of information from an optical tracker to capture the extent and instant of motion. A Digital Single Lens Reflexive camera is employed as the optical tracker to capture the extent and instant of motion. A checkerboard is utilized as a marker that is placed on the coil. Shift of the checkerboard provides the extent of motion, which is captured by camera and is used for motion correction in (MSK)-MRI images.
