Measurement of the Time-of-Flight (TOF) of the 511 keV gammas brings an important reduction of statistical noise in the PET image, with higher precision time measurements producing clearer images. Scintillating crystals are used to convert the 511 keV annihilation photon to an electron of ∼ 511 keV energy via the photoelectric effect; it is necessary to determine with precision the position and time of this conversion within the scintillating crystal. We propose using an array of crystals cut…

TLDR
Evaluating the time-of-flight (TOF) resolution improvement that could be obtained using an easy crystal block modification which enables depth of interaction (DOI) assessment and simplifies the detector assembling process showed that the best TOFr was obtained by leaving the partial saw cuts empty.

TLDR
It is demonstrated that a simple weighted-average estimator can achieve a comparable performance as the more complex maximum likelihood estimator in comparison to the Cramér-Rao lower bound.
