Journal Article
Performance Evaluation of the GE Healthcare eXplore VISTA Dual-Ring Small-Animal PET Scanner
TL;DR: The combination of high spatial resolution, resolution uniformity, sensitivity, and count rate performance, made possible in part by the novel use of phoswich detector modules, confers significant technical advantages over machines with similar geometry but without DOI correction capability.
Journal ArticleDOI
Depth identification accuracy of a three layer phoswich PET detector module
TL;DR: In this article, the authors describe a PET detector module that provides three levels of depth-of-interaction (DOI) information, including LSO, GSO and BGO.
Journal ArticleDOI
Positron Emission Tomography: Current Challenges and Opportunities for Technological Advances in Clinical and Preclinical Imaging Systems
TL;DR: There are several challenges to using PET imaging systems, including the fundamental trade-offs between resolution and noise, the quantitative accuracy of the measurements, and integration with X-ray computed tomography and magnetic resonance imaging.
Journal ArticleDOI
NEMA NU 4-2008 Comparison of Preclinical PET Imaging Systems

Chatziioannou,Katherine Dinelle,Esmat Elhami,Esmat Elhami,Hans Sonke Jans,Eduardo Lage,Roger Lecomte,Vesna Sossi,Suleman Surti,Yuan-Chuan Tai,Juan José Vaquero,Esther Vicente,Darin Williams,Richard Laforest +19 more
TL;DR: Variation in system design makes direct comparisons between systems from different vendors difficult, and when considering the results from NEMA testing, one must also consider the suitability of the PET system for the specific imaging task at hand.
Journal ArticleDOI
Monte Carlo study of the effects of system geometry and antiscatter grids on cone-beam CT scatter distributions.

TL;DR: A fast MC simulator combining GPU acceleration with variance reduction provided a systematic examination of a range of CBCT configurations in relation to scatter, highlighting the magnitude and spatial uniformity of individual scatter components, illustrating tradeoffs in CNR and artifacts and identifying the system geometries for which grids are more beneficial.
