Abstract
Systems and methods are provided for efficiently performing daily maintenance or quality assurance on proton therapy systems. Specifically, a system is provided which includes a solid-state phantom, a plurality of ionization chambers disposed within the solid-state phantom, and a measuring device coupled to the plurality of ionization chambers and operable to perform radiation measurements of proton beams received within the plurality of ionization chambers. Measurements of proton beams received in the ionization chambers may be used to derive the dose at the ionization chambers and be subsequently compared to pre-generated target data (e.g., data corresponding to proper treatment according to a radiation therapy treatment plan). If the data obtained through the maintenance procedure does not conform to the target data, the proton beam generator may be further calibrated.
