  • Patent number: 11723480
    Abstract: A self-checkout system including a cabinet supported by a floor, a tilt body coupled to a hinge and located inside the cabinet and a support body being slidably coupled to the tilt body. When the support body is located inside the cabinet, the tilt body is balanced about the hinge and the support body is spaced apart from the floor. When the support body is pulled outside the cabinet, a front of the tilt body is rotated about the hinge and the support body engages with the floor.

  • Publication number: 20210396891
    Abstract: The present invention relates to an imaging detector. In order to provide a hybrid X-ray and optical detector with enhanced optical imaging capabilities and a simple design, an imaging detector is provided for capturing optical imaging data and X-ray imaging data. The imaging detector comprises a substrate, a photosensitive sensor, an X-ray scintillator, and an array of optical component arrangements. The photosensitive sensor comprises sensor pixels distributed across the imaging detector. The X-ray scintillator is configured to convert energy of incident X-ray radiation into optical photons. Each optical component arrangement comprises at least one optical component configured for directing incident optical radiation towards the photosensitive sensor. The sensor pixels comprise optical pixels, each coupled with a respective optical component arrangement to receive the incident optical radiation, thereby generating the optical imaging data.

  • Patent number: 9877687
    Abstract: The present invention relates to collimation of X-ray radiation and comprises an X-ray source arrangement for medical imaging, the X-ray source arrangement comprising an X-ray source, and an X-ray beam shutter device. The X-ray source has at least at a first and a second focal spot position distanced apart from each other in a direction transverse to a main radiation direction. The X-ray beam shutter device comprises at least a first pair of shutters defining a first diaphragm, and at least a second pair of shutters defining a second diaphragm. The first pair of shutters is configured for alignment with a first line-of-sight between the first focal spot position and a center of a detector, and the second pair of shutters is configured for alignment with a second line-of-sight between the second focal spot position and a center of a detector. The first and the second diaphragm partly overlap.

  • Publication number: 20160081636
    Abstract: The present invention relates to collimation of X-ray radiation. In order to provide an X-ray collimation suitable for focal spots spaced apart from each other with improved use of the provided radiation beam, an X-ray source arrangement (10) for medical imaging is provided. The X-ray source arrangement comprises an X-ray source (12), and an X-ray beam shutter device (14). The X-ray source is configured to generate X-ray radiation (18) at least at a first (20) and second focal spot position (22) distanced apart from each other in a direction (D) transverse to a main radiation direction (R). The X-ray beam shutter device comprises at least a first pair of shutters (28) defining a first diaphragm (30) for a first X-ray beam generated at the first focal spot position, and at least a second pair of shutters (34) defining a second diaphragm (36) for a second X-ray beam generated at the second focal spot position.

  • Patent number: 6584173
    Abstract: The invention concerns an X-ray examination device, including an X-ray source and an X-ray detector, for forming an X-ray image of an object, an X-ray filter, arranged between the X-ray source and the X-ray detector, and adjusting circuit, connected to the X-ray filter for adjusting it. The adjusting circuit comprises a graphics device, cursor control for defining a region of interest in an image of the object, displayed on the graphics device, and image-processing unit, connected to the X-ray filter, for calculating the region of interest and adjusting the filter accordingly. The X-ray filter includes filter elements having an X-ray absorptivity which can be adjusted by controlling a quantity of X-ray absorbing liquid within the individual filter elements. The filter elements are capillary tubes, and adjusting circuit applies electric voltages to the individual capillary tube for controlling the quantity of X-ray absorbing liquid in the tube.
