Abstract
An apparatus comprising a radiation source, coincident positron omission 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.
Claims17
A method of delivering radiation to living tumor tissue comprising:
- detecting positron annihilation emission paths originating from a tumor that has taken up a PET radiotracer;
- and
- directing radiation from a radiation source mounted on a rotatable gantry to the tumor based on the detected positron annihilation emission paths, 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.
