Abstract: A photon counting pixel read-out chip for medical X-ray imaging with energy windowing is presented. It consists of 32×32 pixels of 200 μm×200 μm size, each of them contains two discriminators and two 18-bit counters. Both discriminator thresholds can be adjusted individually for good image homogeneity and a circuit has been designed to avoid threshold drift. Measurements on the noise behaviour, threshold variation and threshold drift are shown.
