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-of-interaction capability and the first to use iterative resolution recovery algorithms ...

Validation of PeneloPET against two small animal PET scanners [PDF]
2007 IEEE Nuclear Science Symposium Conference Record, 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. PeneloPET was built as a powerful tool for PET simulation, it is easy to use, fast and very accurate.

Image quality assessment using NEMA NU 4/2008 standards in small animal PET scanner
Brazilian Journal of Radiation Sciences, 2019 In Brazil, there are few microPET in use and a quality control protocols standardization are needed to harmonize their use in the research field. Thus, the purpose of this study is to characterize the image quality performance of the microPET scanner ...

Improved dead-time correction for PET scanners: application to small-animal PET [PDF]
Physics in Medicine and Biology, 2013 Pile-up and dead-time are two main causes of nonlinearity in the response of a PET scanner as a function of activity in the field of view (FOV). For a given scanner and acquisition system, pile-up effects depend on the material and size of the object being imaged and on the distribution of activity inside and outside the FOV, because these factors ...

Construction and Evaluation of Quantitative Small-Animal PET Probabilistic Atlases for [18F]FDG and [18F]FECT Functional Mapping of the Mouse Brain [PDF]
, 2013 Automated voxel-based or pre-defined volume-of-interest (VOI) analysis of small-animal PET data in mice is necessary for optimal information usage as the number of available resolution elements is limited. We have mapped metabolic ([18F]FDG) and dopamine
