To integrate the first nozzle-mounted, quad-camera prompt gamma imaging (PGI) system on a clinical proton therapy gantry and to evaluate its efficacy for proton range verification under realistic treatment delivery conditions.

The purpose of this study was to test the ability of a portable gamma camera capable of imaging gammas from 30 – 600 keV gammas to produce 3D imaging and activity quantification of radiopharmaceutical distributions for RPT verification and dosimetry.
