https://doi.org/10.1007/978-3-642-17813-9for homeland security applications. Due to the advantages of low-cost, robustness, and ease of fabrication in large volumes, plastic scintillators have been widely served in portal monitors for gamma gross counting. However, its high-end applications, such as gamma-ray spectroscopy, are severely res

Toward a New Frontier in PET Image Reconstruction: A Paradigm Shift to the Learning-Based Methods,onstruction acceleration will be covered as well. In addition, we will demonstrate how computational and physical modeling of the PET image acquisition process for a cutting-edge PET scanner. Specifically, recent progress in artificial intelligence (AI) or deep learning is rapidly becoming one of th

Spatial Localization of Radioactive Sources for Homeland Security, view of the gamma ray detectors..A way to go around this is to have Mechanical Collimation. In this methodology a raster scanning is used with a single detector of one pixel that is moving around. This is relatively inexpensive but the whole process is rather slow (Hughes and Lightfoot, RadScan 600

Concepts for Solid State Detectors in Space-Based Gamma-Ray Astrophysics,tegies to reduce the effect of radiation damage include choice of orbit, operating procedures, detector geometry and shielding. Space instrumentation in this energy range typically uses detectors developed for nuclear and particle physics: the most common choices are based on scintillators or solid-
