A Unified Analytical Framework for LYSO-SiPM Scintillation Pulse Dynamics
Ao Qiu, Qingguo Xie
Existing scintillation-detector models typically treat scintillation kinetics, optical transport, silicon photomultiplier (SiPM) response, and timing statistics separately, limitin…

Prior-Based Multi-Voltage Threshold Sampling as a Structured Inverse Problem
Ao Qiu, Qingguo Xie
Prior-based Multi-Voltage Threshold (MVT) sampling reconstructs pulse parameters from sparse threshold-crossing times rather than full waveforms, making parameter recovery inherent…

Analytic Model of Trans-axial Sensitivity in Cylindrical PET Systems Based on Solid Angle
Boheng Lin, Zizhuo Xie, Bo Zhang +3
In positron emission tomography (PET), a clear theoretical model describing how system sensitivity varies as a source is moved trans-axially within the field of view (FOV) is lacki…
