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 ...

System electronics for the MiCES small animal PET scanner

2003 IEEE Nuclear Science Symposium. Conference Record (IEEE Cat. No.03CH37515), 2003
The final electronics system for the microcrystal element scanner (MiCES) small animal positron emission tomograph is described. Groups of four position-sensitive photomultiplier tubes (FSPMTs) are connected to an adapter board which provides four output signals from each PSPMT.

"ANIPET" a versatile PET scanner for imaging small animals

1998 IEEE Nuclear Science Symposium Conference Record. 1998 IEEE Nuclear Science Symposium and Medical Imaging Conference (Cat. No.98CH36255), 2002
The authors are presently constructing "ANIPET", a new high spatial resolution PET scanner for imaging small animals. This instrument will be used to investigate new tracers and as a substitute for autoradiography. The instrument uses two pixellated BGO crystal arrays coupled to position-sensitive PMTs. Animals can be imaged in two modes.

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 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 ...

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).

PERFORMANCE EVALUATION OF THE HIGH RESOLUTION SMALL ANIMAL PET SCANNER

Biomedical Engineering: Applications, Basis and Communications, 2003
Molecular imaging is an important technology to clarify biological and medical uncertainties in the 21th century. This is best realized via in vivo imaging of biological processes in small animals. Thus, a special high resolution imager dedicated for small animals is required. We recently installed a high resolution animal positron emission tomography

Development of a Small Animal PET Scanner Using DOI Detectors

IEEE Transactions on Nuclear Science, 2008
A small animal PET scanner using 256-channel PS-PMTs has been designed, constructed, and evaluated. The scanner has twelve detector modules, each of which consists of a double-layer array of LYSO crystals and three PS-PMTs (Hama- matsu R8400-00-M256). In the LYSO crystal block, 32 times 53 crystal elements are optically coupled to 32 times 54 crystal ...
