Description
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 Detectors (HPD) readout by
mean of a VLSI auto-triggering fast Front End Electronic (FEE) encapsulated in the
detector body.
The status of the development program will be discussed after an introduction in
order to recall the basic principles of the concept and the subsequent requirements
to the readout system. The progress on the characterization of the crystal bars, a
key component of the project, will be presented in a separated contribution.
The design of the HPDs and of the FE readout electronic will be described and the
performances obtained with a prototype PET-HPD reported.
Finally, the design of an Event Driven Read-out System under development will be
presented.
