Abstract: In operation of a photon counting detecting system (10), a number of pulse counts output by least one pixel (20) of a photon counting detector in response to experiencing a photon flux density during a sample interval is acquired and a photon flux density (46) or value related thereto corresponding to the pulse counts output by the pixel (20) is determined. A correction (48) for the thus determined photon flux density (46) or value related thereto is determined. A corrected number of pulse counts (52) is determined for the pixel (20) as a function of the thus determined corrected photon flux density value or value related thereto. An image can be displayed that is a function of the corrected number of pulse counts for pixels of the system.
