The EXPLORER project aims to build a 2 meter long total-body PET scanner, which will
provide extremely high sensitivity for imaging the entire human body. It will possess a range …

PET scanner designs have changed markedly over the past 3 decades, with resulting
dramatic improvements in image quality. Many of these advances in scanner technology …

There is a growing interest in the design and construction of a PET scanner with a very long
axial extent. One critical design challenge is the impact of the long axial extent on the …

We describe a long axial field-of-view (FOV) PET scanner for high-sensitivity and total-body
imaging of nonhuman primates and present the physical performance and first phantom and …

Current generation of commercial time-of-flight (TOF) PET scanners utilize 20–25 mm thick
LSO or LYSO crystals and have an axial FOV (AFOV) in the range of 16–22 mm. Longer …

Background The limited axial field‐of‐view (FOV) of conventional clinical positron emission
tomography (PET) scanners (∼ 15 to 26 cm) allows detecting only 1% of all coincidence …

Prompt-gamma (PG) imaging has the potential for monitoring proton therapy in real time.
Different approaches are investigated. We focus on developing multi-slat collimators to …

The NEMA NU-2 standard describes a protocol for measurement of scatter fraction (SF)
using an axially-aligned line source, offset at 45 mm from the central axis, in a cylindrical …

The CaLIPSO project focuses on the development of an innovative energetic-photon
detector. The detector uses a “heavy” organometallic liquid: the TriMethyl Bismuth (TMBi) …

Detectors with depth encoding capability, good energy resolution and good timing resolution
are required to develop high performance whole body and total body PET scanners. In this …
