3G4 students would have seen the virtual CT scanner, used to support some of the lectures on medical image acquisition. The simulator was developed by Anil Kamath, a fourth year project student in the 2006-7 academic year. The goal of this project is to develop something similar for PET. There already exist PET simulators targeted at student radiologists. This one will be different, since it will be targeted at student engineers and will therefore expose details of the signal processing chain. The simulator will need to model both the signal generation process (radioactive decay, Poisson noise, photon attenuation between the emitter and the detectors, detector efficiency, etc) and the image reconstruction process (filtered backprojection, ML-EM, etc). The project would suit a student who has taken Module 3G4 and, preferably though not critically, the third year software project (GF2).

generations of 3G4 students understand the technicalities of CT
imaging. The aim of this project is to develop a similar simulator for
