System Architecture of the LabPET Small Animal PET Scanner

IEEE Transactions on Nuclear Science, 2008
To address modern molecular imaging requirements, a digital positron emission tomography (PET) scanner for small animals has been developed at Universite de Sherbrooke. Based on individual readout of avalanche photodiodes (APD) coupled to LYSO/LGSO phoswich detectors, the scanner supports up to 4608 channels in a 16.2 cm diameter, 11.25 cm axial field ...

Design and construction of the ClearPET/XPAD small animal PET/CT scanner

2009 IEEE Nuclear Science Symposium Conference Record (NSS/MIC), 2009
In this study, we present a small animal hybrid PET/CT scanner for simultaneous X and gamma ray scans of the same field of view. It is based on the high resolution PET scanner demonstrator ClearPET developed within the Crystal Clear Collaboration and on the prototype X-ray hybrid pixel detector XPAD3 developed at CPPM.

Performance characterization of a high-sensitivity small-animal PET scanner

2007 IEEE Nuclear Science Symposium Conference Record, 2007
In this work, we will report solid evidences supporting the proposed compact, dual-head PET scanner design for achieving an unprecedented sensitivity. We will also report our initial imaging results generated by our prototypical scanner with phantoms and rats.

FIRST RESULTS WITH THE CLEARPET SMALL ANIMAL PET SCANNERS

2006
The Crystal Clear Collaboration has designed and built a family of high resolution small animal PET scanners. These were designed to be used in research laboratories and provide maximum modularity and flexibility. The source code of the data acquisition and reconstruction software is freely available to the users.
