Position-Sensitive Silicon Photomultiplier Array with Enhanced Position Reconstruction by means of a Deep Neural Network
Cyril Alispach, Fabio Acerbi, Hossein Arabi +4
Single-photon sensitive detectors like Silicon Photomultipliers are widely used in many medical imaging applications. By using detectors with position resolutions, it is possible t…
Performance Evaluation of a Position-Sensitive SiPM-based Gamma Camera for Intraoperative Imaging
Aramis Raiola, Fabio Acerbi, Cyril Alispach +4
The POSiCS camera is a handheld, small field-of-view gamma camera developed for multipurpose use in radio-guided surgery (RGS), with sentinel lymph node biopsy (SLNB) as its benchm…
Probing Stellar Kinematics with the Time-Asymmetric Hanbury Brown and Twiss Effect
Lucijana Stanic, Ivan Cardea, Edoardo Charbon +11
Intensity interferometry (II) offers a powerful means to observe stellar objects with a high resolution. In this work, we demonstrate that II can also probe internal stellar kinema…
Exploiting light coherence in astrophysics
Vitalii Sliusar, Domenico Della Volpe, Benjamin Garcia +7
The Hanbury Brown-Twiss (HBT) effect, discovered in the 1950s and further developed in the 1960s, was originally used to estimate stellar angular diameters through intensity correl…
Stellar physics at sub-nanoradian angular resolution
P. Batista, J. Biteau, C. Carlile +36
Many stars -- if they could be imaged with enough angular resolution -- would exhibit features expected from theory but not possible to extract from spectra. We may group these by…
Quantitative Determination of Spatial Resolution and Linearity of Position-Sensitive LG-SiPMs at Sub-Millimeter Scale via Ricean Distribution Fitting
Aramis Raiola, Fabio Acerbi, Cyril Alispach +4
Position-sensitive SiPMs are useful in all light detection applications requiring a small number of readout channels while preserving the information about the incoming light's int…
