  • Patent number: 11617551
    Abstract: An X-ray detector unit is disclosed. In an embodiment, the X-ray detector unit includes: at least one analysis unit to process electrical signals delivered from a coupled converter unit and operatable by an operating voltage; an adjustable voltage supply, coupled to the at least one analysis unit, to provide an adjustable supply voltage; an identification unit, assigned to the at least one analysis unit, to provide identification information about the at least one analysis unit in a readable manner; and a communication unit, coupled to the adjustable voltage supply, to read the identification information provided from the identification unit, and based upon the identification information provided, to adjust the adjustable voltage supply to equate the provided supply voltage to the operating voltage of the at least one analysis unit.
    Type: Grant

  • Patent number: 11197644
    Abstract: An X-ray imaging apparatus includes a detection unit, having an X-ray detector and a stray radiation collimator in stacked arrangement, and an X-ray source opposite the detection unit. The X-ray source is embodied, starting from a focal point, to emit X-rays towards the X-ray detector. The X-ray detector has a sensor plane and is subdivided in a first direction into a plurality of detector elements. Each detector element of the plurality of detector elements is embodied to convert the X-rays impinging on a surface region, assigned to the detector element, of the sensor plane into an electrical pixel measurement signal. The stray radiation collimator has a plurality of collimator walls. The collimator walls are arranged over the surface region of a detector element of the plurality of detector elements, such that a shadow cast by a respective collimator wall completely overlaps with the surface region of the corresponding detector element.

  • Patent number: 10976448
    Abstract: A reference-voltage system is for a radiation detector. The reference-voltage system includes a voltage reference; and a plurality of sensor units, each sensor unit of the plurality of sensor units including one or more sensor elements, and the voltage reference being configured to provide a reference voltage for the plurality of sensor units. A voltage reference is further provided to provide a reference voltage for a plurality of sensor units. A radiation detector, a medical imaging modality and a method for operating the modality are also described.

  • Publication number: 20050029463
    Abstract: A detector module for a detector for the detection of ionizing radiation, in particular for use in a computer tomography machine, includes a printed circuit board and an array with a plurality of radiation-electrical transducer elements for the conversion of incident electromagnetic radiation into an electrical output signal. The printed circuit board includes a recess in which a plate, firmly connected to the printed circuit board is placed. The plate in turn—indirectly or directly—carries the array.
