of parts of the initial charge cloud in neighbouring pixels. As the probability for this cross talk increases towards pixel edges, it is more prominent in detectors with smaller pixel size. Furthermore, fluorescence of the detector material above its K-edge can lead to additional charge carriers that add to the effect of charge-sharing. Especially in photon counting detectors, charge sharing can lead to errors in the signal count.
