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...

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...
