Abstract

A portable, pulsed digital x-ray imaging device has been developed. The system is intended to be used in explosive ordnance disposal, police and customs baggage inspection and nondestructive testing (NDT). The x-ray source is a portable flash x-ray source. Image acquisition is performed by a charge-coupled-device (CCD) imaging sensors which view the output of a x-ray scintillation screen via an optical system. The construction of the system, its specifications, and its test results are presented. In addition, we study the signal- to-noise ratio, lesion detectability and detective quantum efficiency of the system, and obtain the main factors affecting the performance of the system. This study may help us designing and evaluating optically-coupled CCD x-ray imaging systems effectively.
