Features of the NIH atlas small animal PET scanner and its use with a coaxial small animal volume CT scanner [PDF]

Proceedings IEEE International Symposium on Biomedical Imaging, 2003
ATLAS (Advanced Technology Laboratory Animal Scanner), a small animal PET scanner designed to image animals the size of rats and mice, is about to enter service on the NIH campus in Bethesda, Maryland. This system is the first small animal PET scanner with a depth-ofinteraction capability and the first to use iterative resolution recovery algorithms ...

Characterization of the Ferrara animal PET scanner

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2002
A dedicated small animal PET scanner, YAPPET, was designed and built at Ferrara University. Each detector consists of a 20 20 matrix of 2 2 30 mm 3 YAP:Ce finger-like crystals glued together and directly coupled to a Hamamatsu position sensitive photomultiplier. The scanner is made from four detectors positioned on a rotating gantry at a distance of

Performance Assessment of a Preclinical PET Scanner with Pinhole Collimation by Comparison to a Coincidence-Based Small-Animal PET Scanner [PDF]

Journal of Nuclear Medicine, 2014
PET imaging of rodents is increasingly used in preclinical research, but its utility is limited by spatial resolution and signal-to-noise ratio of the images. A recently developed preclinical PET system uses a clustered-pinhole collimator, enabling high-resolution, simultaneous imaging of PET and SPECT tracers. Pinhole collimation strongly departs from

Spatial Resolution and Sensitivity of the Inveon Small-Animal PET Scanner [PDF]

Journal of Nuclear Medicine, 2009
The Inveon small-animal PET scanner is characterized by a large, 127-mm axial length and a 161-mm crystal ring diameter. The associated high sensitivity is obtained by using all lines of response (LORs) up to the maximum ring difference (MRD) of 79, for which the most oblique LORs form acceptance angles of 38.3 degrees with transaxial planes.

Validation of PeneloPET against two small animal PET scanners [PDF]

2007 IEEE Nuclear Science Symposium Conference Record, 2007
Proceeding of: 2007 IEEE Nuclear Science Symposium Conference Record (NSS'07), Honolulu, Hawaii, USA, Oct. 27 - Nov. 3, 2007 PeneloPET is a Monte Carlo application based on PENELOPE. We present here the new features and results of validation tests for the new version of PeneloPET that has been compared against data from real scanners.

Influence of Multiple Animal Scanning on Image Quality for the Sedecal SuperArgus2R Preclinical PET Scanner

Frontiers in Physics, 2021
Background: Increased throughput in small animal preclinical studies using positron emission tomography leads to reduced costs and improved efficiency of experimental design, however the presence of multiple off-centre subjects, as opposed to a single ...

Comparison of the Amyloid Load in the Brains of Two Transgenic Alzheimer’s Disease Mouse Models Quantified by Florbetaben Positron Emission Tomography

Frontiers in Neuroscience, 2021
Alzheimer’s disease (AD) is characterized by formation of amyloid plaques and neurofibrillary tangles in the brain, which can be mimicked by transgenic mouse models.
