PET-based geometrical calibration of a pinhole SPECT add-on for an animal PET scanner

Physics in Medicine and Biology, 2013
We developed SPECT imaging capability on an animal PET scanner to provide a cost effective option for animal SPECT imaging. The SPECT add-on sub-system was enabled by mechanically integrating a multiple-pinhole collimator in the PET detector ring. This study introduces a method to calibrate the geometrical parameters of the SPECT add-on using the PET ...

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.

Design Considerations for Small Animal PET Scanners

2014
Positron emission tomography (PET) is an established imaging technique currently used for the clinical management of disease in oncology, cardiology and neurology [1–3]. PET is nowadays integrated in the clinical routine and is acknowledged as a sensitive clinical molecular imaging method.

Evaluation of the first Silicon Photomultiplier matrices for a small animal PET scanner

2008 IEEE Nuclear Science Symposium Conference Record, 2008
A high resolution small animal PET scanner that employs Silicon Photomultiplier (SiPM) matrices as photodetectors is under development at the University of Pisa. The first SiPM matrices fabricated by the Center for Scientific and Technological Research, FBK-irst, Trento, Italy, are being evaluated for this purpose.

"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.

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 ...

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.
