Feasibility of a Pair-Production Positron Annihilation Coincidence Counting during Photon Radiotherapy

PET imaging of positrons emitted during megavoltage radiotherapy has not been implemented due to concern of high-count rates. This computational study explores the feasibility of coincidence-counting experiments using two scintil...

Feasibility of Biology-Guided Radiotherapy of Small Tumors with Extended Field of View PET Detectors

The RefleXion X1 system requires activity concentration (AC) >5 kBq/mL for successful biology-guided radiotherapy (BgRT). We evaluated whether the extended field-of-view (FOV) PET detector in a can lower this AC threshold and exp...
