Abstract

Using solutions of spectral transport-of-intensity equations, we have demonstrated a single step method to retrieve absorption and phase changes for a wide range of x-ray imaging energies and material composition. We simulated a Cadmium-Zinc-Telluride based spectral detection system using a cascade model for investigations of breast mass and microcalcification detectability when using both absorption and phase images simultaneously.
