Performance evaluation of the high resolution small animal PET scanner

, 2012
[[abstract]]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.

In vivo tumor imaging in mice using a state-of-the-art clinical PET/CT in comparison with a small animal PET and a small animal CT.

, 2006
The aim of this prospective study was to assess the feasibility of a state-of-the-art clinical PET/CT scanner for in vivo tumor imaging in mice in comparison to a small animal PET scanner and a small animal CT scanner.

SiliPET: An Ultra High Resolution Design of a Small Animal PET Scanner Based on Double Sided Silicon Strip Detector Stacks

, 2006
We investigated the capabilities of a small animal PET scanner, named SiliPET, based on four stacks of double sided silicon strips detectors. Each stack consists of 40 silicon detectors with dimension 60 60 1mm3. These are arranged to form a box 5

Non-invasive imaging of acute renal allograft rejection in rats using small animal F-FDG-PET.

PLoS ONE, 2009
BackgroundAt present, renal grafts are the most common solid organ transplants world-wide. Given the importance of renal transplantation and the limitation of available donor kidneys, detailed analysis of factors that affect transplant survival are ...

Event-by-event motion compensation for small animal PET

, 2007
In small animal PET imaging anaesthesia is usually required to eliminate motion. However, both anaesthesia and the alternative of forcibly restraining the animal, can disturb the very biochemical pathways that are of most interest in the brain.

FPGA-Based Data Acquisition System for a Positron Emission Tomography (PET) Scanner

, 2008
(FPGAs) are capable of performing complex discrete signal processing algorithms with clock rates of above 100MHz. This combined with FPGAs low expense, ease of use, and selected dedicated hardware make them an ideal technology for a data acquisition ...

Monte Carlo simulations study of non-collinear gamma-ray cascade correlation emissions for medical imaging

Brazilian Journal of Radiation Sciences
Conventional imaging techniques such as SPECT and PET cannot directly identify the positions of individual decaying nuclei. As such, they heavily rely on statistical backprojection for image point reconstruction.

Performance Evaluation and MR Compatibility Assessment of an Optical Fibre Based Pre-Clinical MR-Compatible PET Scanner

, 2008
We have designed and constructed a small animal MR-compatible PET system for fully simultaneous MR/PET acquisitions. The scanner uses long optical fibres to distance the field sensitive PET PMTs from the high magnetic field at the centre of an MR scanner.
