Abstract: 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).-

Abstract: Aspects of the present disclosure relate to a photon counting detector and to a read-out integrated circuit to be used in such detector. Aspects of the present disclosure particularly relate to X-ray applications.
According to an aspect of the present disclosure, the detector comprises an electrical ground plane arranged at or near an interface between the carrier and at least one ROIC die. Each ROIC die comprises an extension region that laterally extends beyond the photon conversion assembly, wherein peripheral circuitry for a given ROIC die is arranged in the extension region of that ROIC die. The detector comprises at least one electrical connection that connects the power supply line that is arranged on the carrier to the peripheral circuitry of the at least one ROIC die.-

Abstract: The present invention relates to an image sensor and to an imaging system comprising such a sensor. According to the invention, the overall conversion curve describing the conversion between photon flux and digital number comprises a first region in which the conversion is essentially linear and a second region in which the conversion is essentially non-linear.
According to the invention, the non-linearity of the second region is obtained by operating the photodiode of the image sensor in its non-linear range and by changing the gain associated with the conversion between pixel voltage and digital number.-
