The DRAGO gamma camera

Review of Scientific Instruments, 2010
In this work, we present the results of the experimental characterization of the DRAGO (DRift detector Array-based Gamma camera for Oncology), a detection system developed for high-spatial resolution gamma-ray imaging. This camera is based on a monolithic array of 77 silicon drift detectors (SDDs), with a total active area of 6.7 cm2, coupled to a ...

Impact of aperture-thickness on the real-time imaging characteristics of coded-aperture gamma cameras

Nuclear Engineering and Technology, 2021
The mask parameters of a coded aperture are critical design features when optimizing the performance of a gamma-ray camera. In this paper, experiments and Monte Carlo simulations were performed to derive the minimum detectable activity (MDA) when one ...

X-ray afterglow detection of the short gamma-ray burst 991014 [PDF]

, 2000
GRB 991014 is one of the shortest gamma-ray bursts detected so far with the Wide Field Cameras aboard BeppoSAX, both in gamma-rays and X-rays. The duration is 9.6 sec in 2-28 keV and 3.2 sec in 40 to 700 keV (as measured between the times when 5 and 95 ...
