In low-energy radiological applications the capability to have reproducible image uniformity and good detection efficiency are relevant issues. A single photon counting system based on a 700 mu m thick silicon pixel detector, to ensure a good detection efficiency, and connected to the Medipix2 read-out chip is a good candidate to realize a low-noise detection system with a stable response. We present the experimental results obtained with this system. The performances obtained with a variable thickness phantom are also reported.
