Claim 0:
1. A magnetic resonance imaging (MM) method for tracking 3D organ motion using high spatial resolution 3D motion states and high temporal resolution motion signature data, the method comprising:
performing, by one or more processors, offline learning comprising generating pairs of 3D motion states and offline motion signatures based on MM images acquired during one or more motion cycles;
generating, by the one or more processors, an online motion signature without image reconstruction; and
performing, by the one or more processors, online signature matching comprising comparing the online motion signature with offline motion signatures to identify a corresponding 3D motion state so as to account for motion during radiotherapy by adapting delivery of radiation according to target position and/or target shape and thereby improve treatment accuracy to reduce toxicity to healthy tissue surrounding a target of the radiotherapy.
