Appropriate energy window width for gamma camera [Persian]
Introduction: Scatter radiation is one of the major sources of error in nuclear medicine data processing. Different methods of scatter correction have been introduced in order to improve the quality of data. However the best method is to avoid recording of scatter photons in acquisition. The only difference between scattered and non-scattered photons is the energy. Pulse height analyzer i...

متن کاملDetermination of Optimum Planar Imaging Parameters for Small Structures with Diameters Less Than the Resolution of the Gamma Camera
Introduction: The limited spatial resolution of the gamma camera hinders the absolute quantification of planar images of small structures. The imaged structures are affected by partial volume effects (PVEs), which can spread activity and lead to underestimation of the regional distribution. The use of optimum planar parameters reduces the impact of the limited spatial resolution of the gamma c...

متن کاملGAMPIX: a Gamma Camera for Homeland Security
Localization of radioactive hot spots is nowadays a major issue for Homeland Security to avoid illegal transit of radiological material or manage post-accidental events. In this context, CEA LIST Institute designed a new gamma camera, called GAMPIX, based on the association of a semiconductor detector with a coded mask. GAMPIX is currently under industrialization by AREVA CANBERRA under the nam...
