The impact of time-of-flight, resolution recovery, and noise modelling in reconstruction algorithms in non-solid-state detectors PET/CT scanners: – multi-centric comparison of activity recovery in a 68Ge phantom

The first clinical advance in reconstruction algorithm after iterative reconstruction, was the developments of time-of-flight [1]. This was possible thanks to the introduction of scintillators with optimal timing resolution and good stopping power, as lutetium oxyorthosilicate (LSO) and lutetium-yttrium oxyorthosilicate (LYSO), coupled to fast photomultipliers tubes and improved electronics [2,3].
