  • 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: 9322938
    Abstract: A detector module for a radiation detector is disclosed. In at least one embodiment, the detector module includes a converter layer with contacts, arranged distributed over an area on the rear side, for transmitting electrical signals, wherein the contacts are routed, by way of rewiring, to target contacts on a target region that is smaller than this area. This provides the conditions for simple and secure signal routing between the contacts on the converter layer and readout electronics. In particular, this is successful if a substrate layer used for stabilization purposes has a cutout for the target region, through which cutout the target contacts are directly connected to the signal-routing lines of readout electronics.

  • Patent number: 8080803
    Abstract: A detector module is disclosed including a plurality of directly converting detector submodules, each with a back contact, and a scattered radiation collimator spanning the detector submodules. For contacting the back contacts, a contacting unit is provided in at least one embodiment and designed so that a contact connection is established between the contacting unit and the counter-electrodes by way of assembly-related proximity of the scattered radiation collimator and the counter-electrodes.

  • Patent number: 8077825
    Abstract: A method is disclosed for acquiring measured data by way of a computed tomography system, wherein the measured data is acquired by a detector unit disposed opposite the radiation source during a rotation of a radiation source around an examination object. In at least one embodiment, the rotation is subdivided into succeeding time segments during each of which measured data is acquired, and each of the succeeding time segments has either a first length or a second length consisting of two predefined lengths.

  • Patent number: 7358501
    Abstract: A detector module is disclosed, having an array of detector elements and a printed circuit board. The printed circuit board includes a first region for holding the array of detector elements and includes at least one second region, angled off relative to the first region. On this at least one second region, signal-processing electronics may be arranged. The vertical design of the detector module allows the design of an area detector to be produced on the basis of a multiplicity of detector modules arranged next to one another. The area detector may be provided for a computer tomograph.
