Detectors for Molecular Imaging Laboratory (DMIL)

The main interest of the Detectors for Molecular Imaging Laboratory (DMIL) is focused on the design and development of new devices that efficiently image radiation emissions in the form of annihilation of positrons (Positron Emission Tomography, PET) and single emitted gamma rays, both in Tomography (Single Photon Emission Computed Tomography, SPECT) and 2D planar imaging (Gamma Camera). The group has lately focus on the development of gamma ray detector blocks based on SiPM photosensors and LYSO monolithic scintillation crystals. We are the first group making it possible to accurately measure 511 keV impacts in the whole monolithic scintillation volume. New photosensors, readout techniques, as well as crystal types are always under investigation. The goals of our research are to design devices beyond the current state-of-the–art instrumentation, in terms of sensitivity, spatial, energy, and temporal resolutions.
The group is working on different fields such as crystals types and treatments, readout electronics, data acquisition systems, simulations, detectors characterization, timing resolution experiments, to name but a few. In the following there is a summary of most relevant projects where most of these fields play a role.
