Abstract
An apparatus, method and system for measurement of radiation during or directly following hadron therapy treatment for dose and range verification purposes accomplished through measurement of prompt gamma and other beam-induced radiation. One example includes the measurement of secondary prompt gamma radiation during proton and carbon ion beam irradiation. The measurement can also be made of other beam-induced radiation results. The measurement of gamma radiation or other beam-induced radiation allows for optimization of radiation dose disposition to the target tissue, with improved sparing of surrounding critical structures and normal tissue. Adjustments to a radiation treatment may be made as needed based on actual and measured applied dosages.
