摘要： A detector arrangement and/or a semiconductor-based image sensor with a plurality of detector elements or image pixels is described, which each have an integrated SD-(Sigma Delta) Modulator (20 to 29) or an integrated SD-A/D-(Sigma Delta Analog/Digital) converter (20 to 30), as well as particularly such a detector arrangement and/or such an image sensor on the basis of a CMOS-semiconductor. Particularly on the basis of the differential version and/or the multi-phase structure of the SD modulator and the SD-A/D converter, a detector arrangement and/or an image sensor with specially high noise robustness, a high dynamic range and a lesser noise can be produced, so that this is particularly suitable for usage in Computer Tomography (CT) apparatus.

摘要： The present invention provides a radiation sensor (104) that has a plurality of sensor elements, wherein each sensor element has a photoelectric detection portion and an integrated current to frequency converter for a built-in analog digital conversion of an acquired analog signal being indicative of an intensity of electromagnetic radiation impinging on the photoelectric detection part. Typically, the detector element corresponds to a pixel of a light detector, such as a photodiode. Preferably, the current to frequency converter as well as the photoelectric conversion portion are arranged besides one another on a common substrate and are implemented on the basis of CMOS technology allowing for a costs efficient mass production of the radiation sensor.
