255 Objectives Quantitative assessment of PET/CT scanner performance is typically
performed using the NEMA NU-2 standard. However, this standard does not use metrics that …

559 Objectives Time-of-flight (TOF) PET has regained popularity for improving image quality
and lesion detectability in clinical PET examinations. Using TOF technology, the spatial …

The use of different scanners, acquisition protocols, and reconstruction algorithms has been
identified as a problem that limits the use of PET in multicenter trials. The aim of this project …

Spatial resolution is an important parameter for assessing the performance of positron
emission tomography (PET) systems but this apparently simple measurement is complicated …
