We present results on the characterization of the Clear-PEM breast imaging scanner. Clear-PEM is a dual-head Positron Emission Mammography scanner using APD-based detector modules that are capable of measuring depth-of-interaction (DOI) with a resolution of 2 mm in LYSO:Ce crystals. The full system comprises 192 detector modules in a total of 6144 LYSO:Ce crystals and 384 32-pixel APD arrays...

We present the experimental demonstration of a new geometrical concept for high resolution PET imaging, immune from parallax error and magnetic field. We aim to overcome the main performance limitations of standard PET cameras (with radially arranged crystals), whose lack of Depth Of Interaction of the 511 keV gamma-ray and incapability of recognizing Compton events inside the crystals cause a...

There exist some commercial environmental alarm /monitoring and health safety related devices operating in the ionization mode, for example smoke detectors, medical x-rays and charged particles dosimeters and so on. Based on our recent studies, conditions were found for the stable operation of some micropattern and wire type gaseous detectors in air with high gas gains. This enables to operate...

Future high-energy physics (HEP) experiments as well as next generation medical imaging applications are more and more pushing towards better scintillation characteristics. One of the problems in heavy scintillating materials is related to their high electronic density, resulting in a large index of refraction. As a consequence, most of the scintillation light produced in the bulk material is...
