A model of spatial resolution uncertainty for Compton camera imaging [PDF]
EPJ Web of Conferences, 2023 Compton cameras use a pair of detectors to record the energy deposited during Compton scattering and photoabsorption of gamma ray photons. By inverting the forward model for these detection events, the 3D radioactive source distribution can be recovered ...

Broad band X-ray spectral properties of Gamma-ray bursts with BeppoSAX [PDF]
, 1997 In about one year, five gamma-ray bursts were simultaneously observed with the Wide Field Cameras and Gamma Ray Burst Monitor aboard the BeppoSAX satellite. From some of them X-ray afterglow emission has been clearly detected with the same satellite.

First in-beam tests on simultaneous PET and Compton imaging aimed at quasi-real-time range verification in hadron therapy [PDF]
EPJ Web of Conferences, 2022 Hadron therapy with protons has advantages with respect to conventional radiotherapy because of the maximization of the dose at the Bragg peak. As a drawback, and because of different systematic uncertainty sources, a quasi-real time monitoring for the ...

Pose2Sim: An End-to-End Workflow for 3D Markerless Sports Kinematics—Part 1: Robustness
Sensors, 2021 Being able to capture relevant information about elite athletes’ movement “in the wild” is challenging, especially because reference marker-based approaches hinder natural movement and are highly sensitive to environmental conditions. We propose Pose2Sim,

Development of an advanced Compton camera with gaseous TPC and scintillator
, 2004 A prototype of the MeV gamma-ray imaging camera based on the full reconstruction of the Compton process has been developed. This camera consists of a micro-TPC that is a gaseous Time Projection Chamber (TPC) and scintillation cameras.
