camera performance characteristics

It can be seen that the spatial resolution of a gamma camera deteriorates with increasing source-to detector distance and increasing density of the medium e.g. air versus water. Thus spatial resolution is degraded in patient

In this article, we present a new generation of gamma camera developed by CEA LIST and called GAMPIX. The first part of this article summarizes the characteristics of this

With the gamma-ray imaging technique being widely researched and developed (Xing, 2008; Sun et al., 2015; Shifeng et al., 2016; Wahl et al., 2015), it is crucially important to

Performance Parameters of Gamma Cameras The quality and detail of an image obtained by gamma cameras are affected by several parameters associated with these imaging systems.

This portable gamma camera has a high (LEAP) planar sensitivity, high energy and spatial resolutions that are comparable to other available gamma cameras, and it exhibits superior
