Uncertainty‐aware gamma interaction localization and reconstruction in PET

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Precise localization of gamma‐ray interactions inside scintillation detectors is essential for high‐resolution positron emission tomography (PET) imaging. Although machine learning methods have demonstrated strong performance in gamma interaction positioning, most existing approaches do not quantify event‐level uncertainty, leaving ...

SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications

Small, Volume 22, Issue 28, 18 May 2026.
This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.

A simulation framework for SiPMs

Journal of Instrumentation
Abstract We present a Python module for simulating Silicon Photo-Multipliers. This module allows users to perform noise analyses: Dark Count Rate, crosstalk, and afterpulsing. Furthermore, the simulation framework novelty is the capability of simulating assemblies of SiPM arrays for large area detectors like Ring Imaging Cherenkov ...

Characterizing the Signals and Backgrounds in a Low Earth Orbiting Cherenkov Detector, and Background Mitigation Strategies

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Cherenkov detectors have been used in space for decades to measure Galactic Cosmic Rays (GCRs), Solar Energetic Particles (SEPs) and trapped particles. We present proof‐of‐concept GRAS/Geant4 simulations to both show that a cubic fused silica Cherenkov detector with SiPM in LEO has a good sensitivity to SEP and GCR protons as a function of cut‐
