Abstract :
Spectroscopic X-ray imaging enhances image contrast and provides advanced object information due to energy resolution. The Medipix-2 is a photon counting semiconductor detector and features two energy thresholds for spectroscopic imaging. The aim of this study is to present the development of optimized threshold adjustment masks with small energy windows of about 3 keV and to demonstrate spectroscopic X-ray imaging using the example of an integrated circuit.
