PROBLEM TO BE SOLVED: To provide systems and methods for use in emission guided radiation therapy.SOLUTION: Described herein are the systems and methods for positioning a radiation source with respect to one or more regions of interest in a coordinate system. Such systems and methods may be used in emission guided radiation therapy (EGRT) for the localized delivery of radiation to one or more patient tumor regions. These systems comprise a gantry movable about a patient area, where a plurality of positron emission detectors and radiation sources are arranged movably thereon, and a controller. The controller is configured to identify a coincident positron annihilation emission path and to position the radiation source to apply a radiation beam along the identified emission path.SELECTED DRAWING: Figure 1 |
