Purpose There is a growing interest in extending the axial fields‐of‐view (AFOV) of PET
scanners. One major limitation for the widespread clinical adoption of such systems is the …

We evaluated the performance characteristics of the eXplore VISTA dual-ring small-animal
PET scanner, a stationary, ring-type, depth-of-interaction (DOI) correcting system designed …

We developed a prototype system to evaluate the feasibility of using a PET insert device to
achieve higher resolution from a general-purpose animal PET scanner. Methods: The …

Three-dimensional (3D) PET acquisition has the potential to reduce image noise but the
advantage of 3D PET for studies outside the brain has not been well established. To …

Background The aim of this study is to conduct physical performance evaluation on the
uMI550 whole-body PET/CT system according to the NEMA NU2-2018 standard. Methods …

Objective The objective of this study was to perform a narrative review of digital Positron
emission tomography-computed tomography (PET-CT) scanners, focussing on the current …

Parallax error caused by the detector crystal thickness degrades spatial resolution at the
peripheral regions of the field-of-view (FOV) of a scanner. To resolve this issue, depth-of …

Abstract National Electrical Manufacturers Association (NEMA) NU 2-2007 performance
measurements were conducted on the Inveon™ preclinical small animal PET system …

The GE Discovery MI PET/CT system has a modular digital detector design allowing three,
four, or five detector block rings that extend the axial field‐of‐view (FOV) from 15 to 25 cm in …

A new positron emission tomography (PET) scanner for whole-body studies has been
developed. The scanner has 720 block detectors, each of which consists of a flat panel …
