Paper Abstract

A kinestatic charge detector (KCD) with fourteen segmented signal collectors was built to evaluate the imaging performance of the single-scan dual energy x-ray KCD system. Those front segments of the KCD collectors will produce a low energy signal and those rear segments will produce a high energy signal. The middle segments between the front and rear work as an inactive filter to increase the separation of mean energies absorbed in the front and rear segments. In this study, the segmented KCD output signals were measured and compared with the Monte Carlo simulated result. An optimal KCD collector configuration is gotten by mapping the low energy and high energy signal amplitude to the predetermined thickness of the lucite-aluminum wedge-phantom (0-228.6 mm lucite and 0-25.4 mm aluminum), and then performing error analysis between the calculated thickness and known thickness.
