Abstract
A method including identification and visualization of materials imaged on an x-ray imaging system. Based on producing a series of energy dependent x-ray images at different energies, analyzing and calculating x-ray attenuation curves of imaged material on pixel or voxel level, filtering and curve comparison to known materials from database. Produced data are depicted in a novel image representation modality in which image values depict identified materials.
