The PENN-PET scanner consists of six hexagonally arranged position-sensitive Nal(TI) detectors. This design offers high spatial resolution in all three dimensions, high sampling density along all three axes without scanner motion, a large axial acceptance angle, good energy resolution, and good timing resolution. This results in three-dimensional imaging(More)
• Accelerated proton computed tomography (pCT). • Parallelized pCT on 60-node cluster, with MPI and CUDA. • Reconstruct 2 billion protons in 6 min. • Speed-up of about 180X over pCT with one CPU + one GPU.
