Time-of-flight (TOF) PET was initially introduced in the early days of PET. The TOF PET scanners developed in the 1980s had limited sensitivity and spatial resolution, were operated in 2-dimensional mode with septa, and used analytic image reconstruction methods. The current generation of TOF ...
This paper provides an update on time-of-flight (TOF) PET with a focus on latest hardware developments leading to current commercial PET/CT instruments. We describe advances in scintillator development, new photosensors and associated electronics readout, and detector designs for utilization in comple...
TOF PET reconstructionPurpose: Time of flight (TOF) PET reconstruction is well known to statistically improve the image quality compared to non-TOF PET. Although TOF PET can improve the overall signal to noise ratio (SNR) of the image compared to non-TOF PET, the SNR disparity between ...

PET BATTLESPLAYER VERSUS PLAYER PLUNDERSTORM Get swept away in the Plunderstorm — a fun, new, limited-time, pirate-themed event of prodigious proportions lasting the next several weeks. Scour the map and try to be the last pirate standing while dashing across the Arathi Highlands to find ...
The World Dart Championships have taken flight this week, and tomorrow teenage sensation Luke Littler will play. He captured the nation's attention this time last year - and it appears he has also driven them out to spend money at Asda. ...
These changes come following a public engagement process on trapping, where trappers, recreationists, pet-owners, and others came together to discuss concerns and find shared solutions to them. The group recommended that Game and Fish develop more information to increase public awareness of trapping ...
The Environmental Effects Assessment Panel (EEAP) is one of three Panels of experts that inform the Parties to the Montreal Protocol. The EEAP focuses on the effects of UV radiation on human health, terrestrial and aquatic ecosystems, air quality, and materials, as well as on the interactive...
