Medical Imaging (PET and SPECT)
Our objective is to develop image reconstruction techniques, modeling/simulation tools and accurate attenuation and scatter correction techniques for Positron Emission Tomography (PET) and Single-Photon Emission Computed Tomography (SPECT), as well as the assessment of new possible designs of PET detection modules using sophisticated Monte Carlo techniques. We are particularly interested in improving the quality and quantitative accuracy of nuclear medicine images, and statistical analysis of different reconstruction algorithms and attenuation and scatter correction techniques. A strong interest is arising in the field of neuroimaging to stimulate the different groups active in the field in the Geneva region. Within this direction, we are particularly interested in developing brain activation protocols using nuclear medicine technology (15O-H2O PET and 99mTc-HMPAO SPECT) to study brain function particularly in memory and cognitive aging. More recently, we were involved in a new project within the Computed Imaging for Medical Applications (CIMA) collaboration on novel design of dedicated high-resolution PET scanners for brain research in collaboration with CERN.
