This project involves the development of techniques for measuring and correcting the effects of motion which can occur in many anatomic regions during the application of an MR imaging sequence. Typically, special "navigator echo" signals are used to monitor the motion. Various corrections can be performed using the navigator echo information. Post imaging corrections using algorithmic iterative corrections can also be performed with or without using navigator echo information. These techniques are being applied to a variety of anatomic regions, in particular to thoracoabdominal and musculoskeletal areas.
