Abstract

A method and an X-ray detector are for correcting a spatially resolved photon scan of the X-ray detector. In an embodiment, the X-ray detector includes processing circuitry configured to: generate, from an incident X-ray photon, a signal contribution in a first electrical signal in a spatially resolved manner, a reference value being defined by an absence of X-ray photons; resolve, in relation to the reference value, positive signal contributions of the first electrical signal and negative signal contributions of the first electrical signal; and provide the positive signal contributions resolved and the negative signal contributions resolved for further processing.
