- Abstract
- We present the estimated performance of a multiply stacked Compton camera made of doublesided silicon strip detectors by using the GEANT4 simulation toolkit including Doppler broadening. The multiply stacked Compton camera consisted of a stack of energy- and position-sensitive detectors, such as double-sided silicon strip detectors. The Compton scattering occurring in each detector allowed the energy and the Compton scattering angle to be reconstructed even though the gamma rays incident upon each detector were not fully absorbed. The multiply stacked Compton camera was able to achieve an angular resolution of 4.4' in full width at half maximum and all energy resolution of 28.4 keV for 661-keV gamma rays. Our simulation result showed the feasibility of using the multiply stacked Compton camera in the area of medical imaging in an energy range of 200 - 661 keV.
