NUCAM3 is the latest generation of solid-state pixelated gamma cameras developed at Soreq NRC. The NUCAM3 head is based on segmented pad monolithic CdZnTe detectors that currently provide a useful field of view of 18.5 cm 20.1 cm. The camera is designed for cardiac SPECT, breast scintimammography, thyroid, and other small organ evaluation. The camera contains 528 detectors. Each detector is 5 mm thick and is divided to a matrix of 16 square pixels, with a pitch of 2.1 mm. The use of pixelated CdZnTe detectors and low-noise electronics provides a camera with an average energy resolution of 4.5% full width half maximum (FWHM) at 140.5 keV and 9.5% FWHM at 59.6 keV and an intrinsic spatial resolution of 2.1 mm, regardless of the photon energy. We present the analysis of over 1300 CdZnTe monolithic detectors, the physical and imaging characteristics of the NUCAM3 camera and their comparison to state of the art Anger cameras. We show the advantages of CdZnTe technology, which are due to the camera pixel structure and superior energy resolution. These advantages lead to better detectability of small size cold and hot lesions in a scatter environment.
There has been presented a brief description of test equipment and instrumentation for recording spatial-time parameters of a lightning at the International Center for Lightning Research & Testing (ICLRT) in Camp Blanding that belongs to the University of Florida as well as the first results of Russian image converter cameras test when recording a trigger lightning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
