  • Publication number: 20240107638
    Abstract: In a method for determining a target processing state of a cooking product to be treated using a cooking appliance, a set of images of the cooking product in different processing states is provided to a user, with measurement signatures being stored for the images. When the user selects one of the images, the cooking appliance assumes a corresponding one of the measurement signatures associated with the selected image as a target measurement signature.

  • Publication number: 20220354449
    Abstract: The present invention relates to a system (10) for X-ray dark-field, phase contrast and attenuation image acquisition. The system comprises an X-ray source (20), an interferometer arrangement (30), an X-ray detector (40), a control unit (50), and an output unit (60). An axis is defined extending from a centre of the X-ray source to a centre of the X-ray detector. An examination region is located between the X-ray source and the X-ray detector. The axis extends through the examination region, and the examination region is configured to enable location of an object to be examined. The interferometer arrangement is located between the X-ray source and the X-ray detector. The interferometer arrangement comprises a first grating (32) and a second grating (34). For a first mode of operation: The control unit is configured to control at least one lateral movement transducer (70) to move the first grating or move the second grating in a lateral position direction perpendicular to the axis.

  • Patent number: 11116465
    Abstract: A method of a virtual X-ray colonoscopy includes scanning (204) a dark-field contrast (144) insufflated colon lumen (140) with an X-ray scanner (110) configured for dark-field-contrast, which generates dark-field-contrasted projection data and attenuation projection data. The dark-field-contrasted projection data and the attenuation projection data are reconstructed (206) into one or more dark-field-contrasted images (148).

  • Patent number: 11000251
    Abstract: The present invention relates to a CT imaging system as well as a method for CT imaging is provided. For CT imaging, in practice a scout scan and a main scan of a human subject may be performed. It has been found that a detector signal, provided by a detector which detects the X-ray radiation during the scout scan, may be used on the one hand for determining a respective scout image and on the other hand to determine the bone mineral density of the human subject. Although the scout scan is usually primarily performed for determining the scout image, it is of advantage, if the detector used for detecting the X-ray radiation during the scout scan is formed and/or configured to detect X-ray radiation of a first energy spectrum and to detect X-ray radiation of a different, second energy spectrum. In this case, the detector can provide more precise information about the scout region of the human subject and resulting therefrom in a more precise determination of the bone mineral density.
