Abstract: Systems that can overcome the limitations of current blood flow measurement systems and systems that can track in 3D the explosively driven fragments traveling at 1,000 m/s or faster, will provide temporal resolution of 1 μs, spatial resolution of 50 μm to 1 mm (or finer based on geometry), and allow imaging over at least 122×122 cm2 area are disclosed hereinbelow. These systems use a double-pulsed X-ray generator.

Abstract: A dual-mode, hand-held, digital probe, designed to rapidly localize tissues of interest through gamma detection, and provide high-resolution, real-time images of the suspect area by sensing beta radiation is presented. A position-sensitive solid-state photomultiplier is optically bonded with a hybrid scintillator including a thin Crystalline Microcolumnar Structure (CMS) CsI:T1 scintillator, vapor-deposited directly onto a monolithic (polycrystalline) LYSO scintillator.
