Dual-Energy X-Ray Dark-Field Material Decomposition

Dual-energy imaging is a clinically well-established technique that offers several advantages over conventional X-ray imaging. By performing measurements with two distinct spectra, differences in energy-dependent attenuation are exploited to obtain material-specific information. This information used various applications improve clinical diagnosis. In recent years, grating-based dark-field has received increasing attention the community. The signal originates from ultra small-angle scattering within an object and thus provides about microstructure far below spatial resolution of system. property led number promising future currently being investigated. However, different microstructures can hardly be distinguished current techniques, since detected only represents total amount scattering. To overcome these limitations, we present novel concept called dual-energy material decomposition, which transfers basic decomposition approach attenuation-based modality. We develop physical model algorithms for evaluate proposed experimental measurements. Our results suggest by sampling into microstructured materials possible. Similar imaging, additional microstructure-specific could useful
