Fast full-body reconstruction for a functional human RPC-PET imaging system using list-mode simulated data and its applicability to radiation oncology and radiology
Autor: Martins, Paulo Magalhaes, Crespo, Paulo, Couceiro, Miguel, Ferreira, Nuno Chichorro, Marques, Rui Ferreira, Seco, Joao, Fonte, Paulo
Single-bed whole-body positron emission tomography based on resistive plate chamber detectors (RPC-PET) has been proposed for human studies, as a complementary resource to scintillator-based PET scanners. The purpose of this work is mainly about prov
