Abstract

Idea: Dr. Bernhard Sandkamp, Forchheim; Mathias Hoernig, Forchheim; Dr. Burkhard Groh, Forchheim; Dr. Volker Heer, Forchheim Conventional x-ray systems consist of x-ray source, collimators and the x-ray detector: The object of interest is interposed in the x-ray beam between source and detector. Dual energy is a well known technique to enhance the contrast of the object of interest. This is typically done by exposing two images with different x-ray spectra. Processing those images allows to enhance either bone or tissue contrast.
