Pixelated photon counting semiconductor X-ray detectors like the Medipix feature adjustable energy thresholds allowing selective counting of photons of a specified energy. This development permits for energy selective X-ray imaging with advanced material information. Furthermore the photon counting function principle of these detectors allows X-ray imaging with reduced noise, providing contrast improvement in low contrast objects. The aim of this study is to analyze the behavior of the new Medipix3 detector, especially regarding flatfield correction for X-ray imaging applications. First high resolution low contrast X-ray images and energy selective X-ray images acquired with the Medipix3 detector are presented as well in this paper.
