A method (200, 300) for energy dependent imaging of a region of interest includes the step of exposing (204) and X-ray detector to X-ray photons during an examination period, and separating (206, 208) the X-ray photons into two groups, those with energies above a selected energy threshold, and those with energy threshold, and those with energies above a selected energy threshold, and those with energies below a selected energy threshold. The X-ray photons with energy above the threshold are counted (304) to provide a first energy photon count, while the X-ray photons with energy below the threshold are counted (306) to provide a second energy photon count. The method stores (210) the first energy photon count and the second energy photon count in a memory as examination data, and produces (212) an image by applying an image processing technique to the examination data. |
