Abstract
Portable nuclear imaging devices have been pursed for intraoperative localization and visualization of tumors for a complete removal of malignant tissues. In the proximity of the tumor site, beta imaging is advantageous over gamma imaging due to far less long-range contamination and no need of heavy metal collimation for a compact size. The traditional beta particle detection usually uses a thin scintillation layer coupled with photomultiplier tubes or solid-state detectors, which may lose efficiency due to the multiple conversion steps. In this work, we study the feasibility of direct beta particle detection using gas electron multiplier (GEM) detectors, which are highly sensitive to charged particles. The Geant4 Monte Carlo simulation package is used to simulate Copper-64 (Cu-64) beta particle transportation in different materials. Our simulation results demonstrate that GEM is feasible for direct detection of beta particles and the sensitivity of GEM to beta particles is much higher than gamma photons for certain GEM structures.
