The growing demand on PET methodology for a variety of applications ranging from clinical use to fundamental studies triggers research and development of PET scanners providing better spatial resolution and sensitivity. These efforts are primarily focused on the development of advanced PET detector solutions and on the developments of new scintillation materials as well. However in...

In the attempt to improve system performances of position sensitive gamma-ray detectors with contemporary ease of use and compactness, the use of silicon photodetectors for scintillation readout has become of increasing interest. With respect to the long-established photomultiplier tubes (PMTs), silicon photodiodes (PDs) have the advantages of higher quantum efficiency, smaller...

A brief overview of the history of the development of the so-called 'Silicon Photomultipliers' (SiPM), more precisely - multi-pixel avalanche photodiodes operating above breakdown (or in 'Geiger' mode) will be given. Main features, which determine their potential for bio-medical applications, will be described. Some examples of particular on-going or future developments in this field...

The concept was proposed as a competitive and innovative approach, mainly for a high resolution brain PET scanner, allowing a parallax free 3D image reconstruction with Compton enhanced sensitivity. It is based on axially oriented matrices of 16 x 13 long polished LYSO scintillator bars (e.g. 3.2 x 3.2 x 150 mm3) optically coupled at both extremities to segmented Hybrid Photon...

113. Nuclear medical imaging using beta+ gamma coincidences from 44Sc radio-nuclide with liquid xenon as detection medium

We report on a new imaging technique based on the measurement of the emitter location in the three dimensions with a few mm spatial precision using beta+ gamma emitters. Such coincidences arise from a new kind of radio-nuclides, potentially produced at the ARRONAX cyclotron of Nantes, which emits a gamma-ray quasi simultaneously with the beta+ decay. The principle is to reconstruct the...
