Aims Dual energy CT imaging enables discrimination of materials with similar attenuation coefficients. By acquiring two CT scans at different X-ray energies of the same sample, the energy dependence of the linear attenuation coefficient can be exploited to differentiate between materials. Dual energy CT has been widely used to distinguish bone from vascular contrast agents that contain elements...
