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.
Claims24
An apparatus comprising:
- a rotatable gantry;
- a radiation source mounted on the gantry;
- one or more collimated gamma ray photon detectors mounted on the rotatable gantry, wherein the collimated gamma ray photon detectors are configured to detect a collimated gamma ray photon emission originating from a volume of tissue;
- and
- a controller in communication with the radiation source and the collimated gamma ray photon detectors, the controller configured to rotate the gantry to position the radiation source with respect to the detected collimated gamma ray photon emission and to direct radiation from the radiation source to the volume of tissue, wherein the radiation is applied before the volume of tissue moves substantially.
2 more elements
A method of treatment comprising:
- detecting an individual collimated gamma ray photon emission originating from a volume of tissue using at least one collimated gamma ray photon detector mounted on a rotatable gantry;
- rotating the gantry such that a radiation source mounted on the gantry is positioned with respect to the individual collimated gamma ray photon emission;
- and
- applying radiation to the volume of tissue before the volume of tissue moves substantially.
