The present invention relates to an image sensor and to an X-ray system comprising such image sensor. More in particular, the invention relates to an image sensor wherein dose sensing pixels are used in conjunction with artificial pixels to sense a dose of incoming light or radiation. According to the invention, the image sensor comprises one or more shielded photo-sensitive pixels that are shielded for incoming photons and which are each configured for outputting a further reference voltage, wherein the input voltage of the artificial pixels is set in dependence on the outputted further reference voltage(s).

An array-based C-MOS sensor device is provided with a facility for on the basis of non-destructive cell readout generating a radiation dose-sensing signal. In particular, the facility is arranged for accessing a subset of multiple distributed C-MOS cells across the array and feeding by such accessed cells an algorithmic means for therein generating an overall feedback dose control signalization and/or an over-all trigger signalization.
