Optimization of Medipix-2 Threshold Masks for Spectroscopic X-Ray Imaging

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