Prompt gamma ray in proton therapy is the product of nuclear reaction between proton and target. The characteristic energies and intensities of prompt gamma lines can be used to determine the types of elements and their amounts in the target. In several previous experiments, it was demonstrated that no matter how complex the reaction cross-section is, once the energy of the incident proton and...
This work introduces a Positron Enhanced Prompt Gamma Imaging (PEPGI) technique to improve the image reconstruction from a CdZnTe Compton Camera for use in dose reconstruction during proton therapy. PEPGI uses coincidence 511 keV gamma rays emitted from a target to locate the proton beam line using a PEPT-style algorithm, which is then used to improve Compton Camera Prompt Gamma Imaging (PGI)...
