Advances in animal PET scanners.

The quarterly journal of nuclear medicine : official publication of the Italian Association of Nuclear Medicine (AIMN) [and] the International Association of Radiopharmacology (IAR), 2002
Nowadays, a growing number of research groups shows a great interest for the application of PET and SPECT techniques to the development of new drugs. Preliminary studies on small animals require high performance dedicated scanners with a higher spatial resolution and sensitivity than those of clinical systems.

System Integration of the LabPET Small Animal PET Scanner

2006 IEEE Nuclear Science Symposium Conference Record, 2006
To address modern molecular imaging requirements, a digital positron emission tomography scanner for small animals has been developed at Universite de Sherbrooke. Based on individual readout of avalanche photodiodes (APD) coupled to a LYSO/LGSO phoswich array, the scanner supports up to 3072 channels in a 16.2 cm diameter, 7.5 cm axial field of view ...

PET Scanners Dedicated to Molecular Imaging of Small Animal Models

Molecular Imaging & Biology, 2002
The dramatic advances of biological research in recent years that have focused on the molecular basis of how systems of the body (e.g. cells, organs and the whole organism) function, have increased the need for molecular imaging instrumentation. Of the several imaging modalities available today applied for in vivo studies of research animals, positron ...

System integration of the MiCES small animal PET scanner

IEEE Symposium Conference Record Nuclear Science 2004., 2005
A small animal positron emission tomography scanner for small animals has been developed based on the University of Washington micro-crystal element (MiCE2) detector module design. The scanner, MiCES, uses 72 MiCE2 modules, each consisting of a 22/spl times/22 array of 0.8/spl times/0.8/spl times/10 mm MLS crystals coupled to a Hamamatsu R5900-00-C12 ...

Performance evaluation of the 32-module quadHIDAC small-animal PET scanner.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 2005
The 32-module quadHIDAC is a commercial, high-resolution animal PET scanner, based on gas multiwire proportional chambers.Several scanner parameters that characterize the performance of the system were evaluated in this study, such as spatial resolution, absolute sensitivity, scatter, and count rate performance.

Quantitative YAP-(S)PET small animal scanner: preliminary results

2001 IEEE Nuclear Science Symposium Conference Record (Cat. No.01CH37310), 2005
We have successfully built and characterized small animal PET scanner based on 4 rotating planar detector heads. Each detector module is composed of a matrix of 400 YAP:Ce finger crystals (2/spl times/2/spl times/30 mm/sup 3/ each) directly coupled to position sensitive photomultipliers (Hamamatsu R2486-06).

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.

An animal PET scanner using flat-panel position-sensitive PMTs

Annals of Nuclear Medicine, 2013
To design, build, and evaluate an animal PET scanner, which can be used with non-human primates under conscious condition, incorporating flat-panel position-sensitive photomultiplier tubes (PS-PMTs).The system contains 30 detector modules, each having two PS-PMTs and 16×18 lutetium–yttrium oxyortho-silicate scintillation crystal arrays.

Simultaneous PET/SPECT imaging with the small animal scanner YAP-(S)PET

2007 IEEE Nuclear Science Symposium Conference Record, 2007
To exploit the YAP-(S)PET II scanner intrinsic capability of both PET and SPECT imaging, we have implemented the simultaneous PET/SPECT dual imaging modality. Two opposing heads, equipped with collimator and set in anticoincidence, independently acquire single events (SPECT mode), the other pair of heads detects coincidence events (PET mode).
