Optimizing light collection from thin scintillators used in a beta-ray camera for surgical use


Journal Article

We are developing a 1-2 cm2 area camera for imaging the distribution of beta emitting radiopharmaceuticals at the surface of tissue exposed during surgery. The front end consists of a very thin continuous or segmented scintillator sensitive to betas (positrons or electrons) of a few hundred keV, yet insensitive to gamma rays. The light from the scintillator is piped away through clear fibers into the photon detector (PD). We report here on efforts made to optimize the light collection from < 3 mm thick plastic and CaF2(Eu) scintillators into clear fibers using experimental measurements and computer simulations.
