Implementation of Photonic Crystals into Davis LUT module for GATE simulation.

ABSTRACT: The performance of Positron Emission Tomography (PET) detectors has been constrained by the photodetector collection of optical photons emitted in the scintillator, which was limited to photons reaching the exit surface with an angle larger than the critical angle. Photonic Crystals (PhCs) are periodic nanostructures with sizes comparable to the optical photons' wavelengths, which can break through the critical angle limit. Thorough experimental investigation of PhCs effect on optical harvest in scintillator detectors is complex and costly. Simulation can overcome these challenges. Mainstream software such as GATE does not support PhCs simulation. Here, we generalize the GATE optical model by incorporating the PhCs optical model into the LUT Davis model. We can model the performance of adv
