The sensitometric response of Cd 1-xZn xTe 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 parameters of these solid state-ionization devices. In addition, the dependence of the spatial resolution of a planar Cd 1-xZn xTe substrate on the phantom thickness has been experimentally determined. The results of this study indicate that Cd 1-xZn xTe detectors exhibit a high signal-to-noise ratio (S/N).
