Compton scatter reveals dose deposition

A system and method for directly measuring dose deposition during radiation therapy has been developed by the Mayo Foundation for Medical Education and Research (Rochester, MN). The system uses a Compton camera imager to image photons that have been ejected from the subject due to Compton scattering induced by the radiation treatment. The filing also details a method for reconstructing the acquired Compton scatter photon data to produce an image that shows dose deposition in the subject (WO/2010/141583)
