Building a Hybrid Compton Camera System for Improving Medical Imaging Applications
Compton cameras present a powerful advancement in gamma-ray imaging, offering en-hanced resolution and efficiency over conventional imaging methods for medical applications such as proton therapy and other targeted radiotherapies. Unlike mechanically collimated imaging systems, a two-stage Compton …

Monte Carlo Simulations of Novel Scintillator Detectors and Dosimetry Calculations
… the mechanisms of the radioresponse of tumor cells "in vitro" is of crucial importance as a first step before "in vivo" studies. The dosimetry of 188Re, used to target different lines of cancer cells, has been evaluated by the MC code GEANT4. The simulations estimate the average energy …
