Development and Characterization of a 64 Channel DAQ System for X-ray Imaging

Abstract

X-ray imaging system is widely used in medical imaging equipment, nondestructive testing of industry, and homeland security. In X-ray imaging systems, semiconductor detectors, such as CdTe and CdZnTe (CZT), are used for radiation detection because of their good energy resolution at room temperature. For X-ray imaging, we develop a 64 channels digital data acquisition (DAQ) system which is composed of CdTe array sensor and a FPGA based DAQ system. For increasing convenience of user, we developed software based of Windows OS. We also developed imaging formation algorithm for high resolution imaging results. In this paper, the status and test results of 64 channels DAQ system for X-ray imaging are addressed.because of their good energy resolution at room temperature.
