Paper Abstract

X-ray imaging is popular in medical imaging, non-destructive testing and security. The main techniques of x-ray imaging with semiconductor detector are charge accumulation and photon counting, and the photon counting is expected to identify materials at the same time with taking x-ray photograph by using energy information of x-ray photons. We proposed direct charge handling method to build photon counting system with energy information for x-ray imaging. This method operates the charge from x-ray detector and converts it to encoded digital bit pattern directly without dead time of front end circuit. We simulated and built proposed system to prove operating principals.
