Abstract
The sensitometric response of Cd1-xZnxTe semiconductor detectors using a geometrical chest phantom, within the X-ray diagnostic energy range , has been studied with the aim of optimizing the image quality parame ters of these solid state-ionization devices, In addition, the depende nce of the spatial resolution of a planar Cd1-xZnxTe substrate on the phantom thickness has been experimentally determined. The results of t his study indicate that Cd1-xZnxTe detectors exhibit a high signal-to- noise ratio (S/N).
