Maximizing precision over extended unambiguous range for TOF range imaging systems [PDF]
, 2010 The maximum unambiguous range for time-of-flight range imaging systems is inversely proportional to the chosen modulation frequency. However, increasing the unambiguous range by decreasing the modulation frequency will generally also degrade the range ...

Evaluation of the PETsys TOFPET2 ASIC in multi-channel coincidence experiments
EJNMMI Physics, 2021 Background Aiming to measure the difference in arrival times of two coincident γ-photons with an accuracy in the order of 200ps, time-of-flight positron emission tomography systems commonly employ silicon photomultipliers (SiPMs) and high-resolution ...
