Abstract
Systems and methods for providing image guidance for motion tracking and compensation in magnetic resonance imaging (“MRI”) guided therapies, such as MRI-guided radiation therapies using an MR-linac or other MRI-guided radiation therapy system, are described. Simultaneous orthogonal plane imaging (“SOPI”) is used to acquire images from a first slice that remains static throughout the acquisition, and from a plurality of slices that are orthogonal to the first slice. This first slice can be referred to in some instances as a “tracking” or “navigator” slice, and the plurality of slices that are orthogonal to the first slice can be referred to as “imaging” slices. The tracking slice images can be used to estimate motion of the subject that occurred during the data acquisition, and to track the position of targets (e.g., anatomical targets) during the delivery of radiation treatment.
