CT with photon-counting detectors is an emerging technology that overcomessome drawbacks of the conventional CT with energyintegrating detectors. It candifferentiate individual X-ray photons, so acquired data does not suffer fromelectronic noise. Moreover, photon-counting detectors provide ultra highresolution without increased dose. And finally, detectors provide spectraldata which enables differentiation of different materials in CT data,therefore virtual monoenergetic and non-contrast images can be reconstructed.

Keywords: energy-integrating detector, mo-noenergetic image, photon-counting detector,spectral data, virtual non-contrats image, ultra high resolution
