Abstract: Radiographic studies with the aim of optimizing the imaging
potential of Cd1-xZnxTe detectors for digital chest
radiography have been performed. A geometrical chest phantom has been designed,
and the dependence of both the signal-to-noise ratio and contrast resolution of
a planar Cd1-xZnxTe detector on the phantom thickness has
been experimentally determined. Specifically, the detected signal and noise
contributions were measured and related to phantom thickness. The results of
this study indicate that Cd1-xZnxTe detectors exhibit
both high signal-to-noise ratio and contrast resolution. At present time,
several studies are in process to experimentally identify and quantify the
imaging potential of Cd1-xZnxTe detectors for digital
radiographic applications.
