Including inter-crystal scattering (ICS) events in Positron Emission Tomography (PET) can be beneficial in low-count scenarios such as small-animal imaging, where sensitivity is a limiting factor. To this end, conventional ICS-recovery techniques typically aim to identify the original line of response, usually with insufficient success rates. We have recently proposed a new physics-based...

PET image quality depends on accurately determining the lines of response, which requires precise 3D localization of annihilation photon interactions within the detectors. In pixelated crystal arrays, spatial resolution is inherently limited by crystal size and can only be improved by increasing granularity, at significant cost. Monolithic and semi-monolithic arrays overcome this by inferring...

The growing importance of theranostics and research with long‑lived isotopes demands imaging systems far more sensitive than standard PET or SPECT. Many emerging isotopes lie outside current detector capabilities, resulting in low sensitivity, high background, and poor quantification, as seen with $^{90}$Y verification and $^{124}$I or $^{89}$Sr imaging. The Multiple Emission Tomography (MET)...

A prevailing trend in PET development is the use

of smaller SiPMs to achieve higher spatial resolution. However,
the resulting increase in SiPM quantity places a heavier burden
on the processing hardware. To address this without requiring
upgrades to the underlying readout electronics, multiple SiPM
signals can be multiplexed into a single channel. This approach is
utilized in the...
