Some Positron Emission Tomography (PET) scanners achieve improved resolution or Depth-Of-Interaction (DOI) measurement using avalanche photodiode-based phoswich detectors, with different challenges (noise limitation) than traditional photomultiplier tubes (space limitation). DOI measurement is necessary in small-animal PET for parallax mitigation, while side-by-side phoswich detectors improve resolution without an equal increase in electronics complexity. Future improvements in scanner…

TLDR
The purpose of the fault prioritization module is to help the operator to zero in on the faults that need immediate attention and suggest the IS can greatly benefit the operators in their maintenance task.
Digital timing: sampling frequency, anti-aliasing filter and signal interpolation filter dependence on timing resolution.
TLDR
The main focus of this study is to investigate how the performance of digital timing methods is affected by sampling rate, anti-aliasing and signal interpolation filters, and a so-called sliding test is proposed as a validation tool checking constant timing resolution behavior of a given timing pick-off method regardless of the source location change.

TLDR
This note proposes a multi-time-scale modification of the algorithm in [5] such that convergence is achieved and the new scheme handles a wider class of input signals so that the input can be designed for some purpose.
