Abstract

The detected signal and noise contributions were measured and related to the radiation exposure and tube current tube setting. Furthermore, the detector contrast has been experimentally determined. The experimental results indicate that Cd_1-xZn_xTe detectors have high detector contrast resolution. Therefore, they appear to be very attractive for x-ray digital imaging applications.
