Abstract
An apparatus comprising a radiation source, coincident positron emission detectors configured to detect coincident positron annihilation emissions originating within a coordinate system, and a controller coupled to the radiation source and the coincident positron emission detectors, the controller configured to identify coincident positron annihilation emission paths intersecting one or more volumes in the coordinate system and align the radiation source along an identified coincident positron annihilation emission path.
Claims30
A radiation therapy system comprising:
- a gantry rotatable about a tumor region;
- a radiation source mounted on the gantry;
- a collimation assembly mounted on the gantry and disposed in a radiation path of the radiation source, wherein the configuration of the collimation assembly is adjustable while the gantry is rotating;
- an array of positron annihilation emission detectors mounted along at least a circumferential length of the gantry and configured to detect positron annihilation emission paths from the tumor region;
- and
- a controller in communication with the array of positron annihilation emission detectors and configured to construct a map from the detected positron annihilation emission paths, and wherein the controller is in communication with the radiation source and configured to direct radiation from the radiation source to the tumor region based on the map.

A method for radiation therapy comprising:
- identifying a volume of interest by detecting a plurality of positron annihilation emission paths from the volume of interest using an array of positron annihilation emission detectors mounted on a rotatable gantry;
- constructing a map of positron annihilation emission path activity from the detected positron annihilation emission paths;
- and
- directing radiation from a radiation source mounted on the rotatable gantry to the volume of interest based on the map of positron annihilation emission path activity, wherein directing radiation comprises adjusting a configuration of a collimation assembly that is disposed in a radiation path of the radiation source while rotating the gantry.
