Eliminating spatial distortions in Anger-type gamma cameras
New Journal of Physics, 2012 A procedure to quantify and correct the spatial distortions inherent to Anger-type gamma cameras is presented. It consists in imaging a pattern of regularly spaced holes, assigning to each pair of lattice indices the actual position on the detector and ...

Differences in attenuation pattern in myocardial SPECT between CZT and conventional gamma cameras. [PDF]
J Nucl Cardiol, 2019 BackgroundIn myocardial perfusion imaging (MPI), single-photon emission tomography (SPECT) soft-tissue attenuation by the abdomen, breasts, and lateral chest wall may create artifacts that mimic true perfusion defects.

Preliminary experience with small animal SPECT imaging on clinical gamma cameras. [PDF]
Biomed Res Int, 2014 The traditional lack of techniques suitable for in vivo imaging has induced a great interest in molecular imaging for preclinical research. Nevertheless, its use spreads slowly due to the difficulties in justifying the high cost of the current dedicated ...

New 3D coded aperture collimator for X/gamma-ray wide-field imaging [PDF]
EPJ Web of Conferences, 2023 Remote localization of radioactive sources is vital to the nuclear industry and high-energy astrophysics. One widely used method to localize radioactive sources relies on indirect imaging with coded aperture cameras.

Review of Compton camera imaging technology development
He jishu, 2021 Compton camera (CC) is a new type gamma-ray imaging modality. Because CC has no mechanical collimation structure, it has unique advantages in detection efficiency compared with other gamma-ray imaging modalities.

MASTER prompt and follow-up GRB observations [PDF]
, 2009 There are the results of gamma-ray bursts observations obtained using the MASTER robotic telescope in 2007 - 2009. We observed 20 error-boxes of gamma-ray bursts this period.The limits on their optical brightnesses have been derived.

Gamma-Ray Burst 980329 and its X-Ray Afterglow [PDF]
, 1998 GRB 980329 is the brightest gamma-ray burst detected so far with the Wide Field Cameras aboard BeppoSAX, both in gamma-rays and X-rays. With respect to its fluence (2.6 X 10**-5 erg/s/cm**2 in 50 to 300 keV) it would be in the top 4% of gamma-ray bursts ...
