Abstract
A method for energy dependent imaging of a region of interest includes the step of exposing an X-ray detector to X-ray photons during an examination period, and separating the X-ray photons into two groups, 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 to provide a first energy photon count, while the X-ray photons with energy below the threshold are counted to provide a second energy photon count. The method stores the first energy photon count and the second energy photon count in a memory as examination data, and produces an image by applying an image processing technique to the examination data.
