Crystal identification in positron emission tomography using nonrigid registration to a Fourier-based template.
Published in Physics in Medicine and Biology
Modern positron emission tomography (PET) detectors are typically made from 2D modular arrays of scintillation crystals. Their characteristic flood field response (or flood histogram) must be segmented in order to correctly determine the crystal of annihilation photon interaction in the system. Crystal identification information thus generated is a...
