We are interested in developing technology for medical imaging. The focus of our research is around positron emission tomography (PET), x-ray computed tomography (CT) and general x-ray imaging systems. We simulate from detectors to complete imaging systems using Monte Carlo based methods, design and build detectors, system electronics and prototype systems, develop data correction and image reconstruction algorithms as well as data analysis and visualization tools. We hope the technology and tools we developed can be of great help to clinics in the process of translational medicine.
