Wavelength shifter strips and G-APD arrays for the read-out of the z-coordinate in axial PET modules
/ Braem, André (CERN) ; Chesi, Enrico Guido (CERN) ; Joram, C (CERN) ; Rudge, A (CERN) ; Séguinot, Jacques (CERN) ; Weilhammer, P (CERN) ; De Leo, R ; Nappi, E ; Lustermann, W ; Schinzel, D et al.
The measurements presented in this paper are related to the development of a PET camera based on a 3-D axial geometry with excellent 3-D spatial, timing and energy resolution. The detector modules consist of matrices of long axially oriented scintillation crystal bars, which are individually coupled to photodetectors. [...]

Abstract A very high-resolution small animal positron emission tomograph (PET), which can achieve sub-millimeter spatial resolution, is being developed using silicon pad detectors. The prototype PET for a single slice instrument consists of two 1 mm thick silicon pad detectors, each containing a 32×16 array of 1.4×1.4 mm pads readout with four VATAGP3 chips which have 128 channels low-noise self-triggering ASIC in each chip, coincidence units, a source turntable and tungsten slice collimator.

High Precision Axial Coordinate Readout for an Axial 3-D PET Detector Module using a Wave Length Shifter Strip Matrix
/ Braem, André (CERN) ; Chesi, Enrico Guido (CERN) ; Joram, C (CERN) ; Séguinot, Jacques (CERN) ; Weilhammer, P (CERN) ; De Leo, R (INFN Bari, Bari, Italy) ; Nappi, E (INFN Bari, Bari, Italy) ; Lustermann, W (ETH Zürich, Zürich, Switzerland) ; Schinzel, D (ETH Zürich, Zürich, Switzerland) ; Johnson, I (Paul Scherrer Institut, Villigen, Switzerland) et al.
We describe a novel method to extract the axial coordinate from a matrix of long axially oriented crystals, which is based on wavelength shifting plastic strips. The method allows building compact 3-D axial gamma detector modules for PET scanners with excellent 3-dimensional spatial, timing and energy resolution while keeping the number of readout channels reasonably low.

Scintillator studies for the HPD-PET concept
/ Braem, D (CERN) ; Chesi, Enrico Guido (CERN) ; Ciocia, F (INFN Bari) ; De Leo, R (INFN Bari) ; Joram, C (CERN) ; Lagamba, L (INFN Bari) ; Nappi, E (INFN Bari) ; Séguinot, Jacques (CERN) ; Vilardi, I (INFN Bari) ; Weilhammer, P (CERN)
The spatial, energy, and time resolutions of 10 cm long polished YAP:Ce and LYSO:Ce crystals have been measured. The work is part of the novel HPD-PET concept, based on a full three-dimensional, free of parallax errors, reconstruction of the γ-ray interaction point in 10–15 cm long scintillators. [...]

We describe the design, fabrication and test results of a segmented Hybrid Photon Detector with integrated auto-triggering front-end electronics. Both the photodetector and its VLSI readout electronics are custom designed and have been tailored to the requirements of a recently proposed novel geometrical concept of a Positron Emission Tomograph.
