摘要： The present invention provides a radiation sensor featuring a plurality of individual sensor elements, e.g. pixels, each of which having a radiation detection portion that is adapted to generate an electric current in response to impingement of electromagnetic radiation and a current amplifier for amplifying the photoelectric current generated by the radiation detection portion. Current amplification is therefore performed locally within each pixel of the radiation sensor itself. This local current amplification effectively allows to increase sensitivity and response of the radiation sensor and therefore enables implementation of the radiation sensor on the basis of CMOS technology. By means of the current amplification, the radiation sensor can be adapted for read-out by means of read-out devices and signal processing modules featuring distinct input specifications Further, a bias current required by the pixel implemented current amplifier is reproduced within each pixel and coupled to consecutive or adjacently arranged sensor elements or pixel, thereby providing a cascaded bias current regeneration and bias current distribution scheme.

摘要： The invention relates to an X-ray imaging device (100), particularly a Spectral-CT scanner, that comprises an X-ray source (10) for generating X-radiation with an energy spectrum (P(E,t)) which varies continuously during an observation period (T). In a preferred embodiment, the radiation (X) is attenuated in an object (1) according to an energy-dependent attenuation coefficient μ(E,r), the transmitted radiation is measured by sensor units (22) of a detector (20, 30), and the resulting measurement signal (i(t)) is sampled and A/D converted. This is preferably done by an oversampling A/D converter, for example a ΣΔ-ADC. The tube voltage (U(t)) that drives the X-ray source is sampled with high frequency. In an evaluation system (50), these sampled measurement values can be associated with corresponding effective energy spectra (Φ(E)) to determine the energy dependent attenuation coefficient μ(E,r).

摘要： The invention relates to an X-ray detector with detector elements (1) arranged in a layer. The detector elements (1) contain a scintillator element (2) for the conversion of X-rays (X) into photons (v), a photodiode (5) for detection of the photons (v), and a processing circuit (4) for the processing of electric signals generated by the photodiode (5).

This shielding (3) can in particular be L-shaped. By reduction of the effective thickness of the shielding (3) to a necessary minimum the volume of the scintillator unit (2) can be maximized.

The electrically conductive connection is completely surrounded from the outside. The insulator is formed by an opening which is filled with material. The inner wall is provided with a dielectric coating and/or filled with an electrically insulating or conductive material. The electrically conductive connection is formed with a further opening which is filled with an electrically conductive material and is arranged in the interior of the insulator.
