摘要:
An X-ray system, in particular a computed tomography system, for acquiring projection data of an examination subject is described. In an embodiment, the X-ray system includes an X-ray emitter arrangement including a number of X-ray radiation sources and a number of photon-counting detectors including at least two detection thresholds. In this configuration, the X-ray emitter arrangement is embodied so as to generate X-ray radiation including at least two X-ray radiation spectra. Furthermore, the number of photon-counting detectors are arranged and embodied so as to detect at least the X-ray radiation passing through the examination subject in an energy-resolved manner in the form of projection data. An image reconstruction method is also disclosed.
