Patient motion is a major problem in MR exams. We propose here an algorithm that relies on the known position and orientation of the anatomy at the beginning of a scan and uses fast three-plane localizers to update this just before image acquisition. The algorithm finds a rigid transform that best aligns the 3P localizers to the full initial volumetric localizer. This transform is then used to compute new patient-centric scan plane prescription. We have incorporated this approach in a clinical MR system and demonstrated its usefulness in automatically obtaining consistent imaging planes in brain exams in presence of motion.
