Abstract :
We present a compact acquisition system for digital radiology, based on GaAs detectors. The system is based on a custom VLSI circuit set, with analog and digital functions for the acquisition of radiological images in a wide range of applications. The circuit architectures and the operating principles are presented. We use a broad spectrum X-ray tube and try to exploit the full physical information contained in the incident radiation by means of both single photon counting and energy measurement of each photon.
