  • Patent number: 10610177
    Abstract: A first x-ray image is acquired at a predetermined position of a focal point and with a first orientation of an x-ray tube of an x-ray device. Subsequently, the x-ray tube is adjusted by rotating about a predetermined angle and by positioning, wherein the focal point is situated in the predetermined position prior to the adjustment and after the adjustment. After the adjustment, the x-ray tube is situated in a second orientation. Subsequently, a second x-ray image is acquired at the predetermined position and with the second orientation. A combined x-ray image from at least the first and second x-ray image is produced.

  • Patent number: 10565707
    Abstract: A computer-implemented method for identifying features in 3D image volumes includes dividing a 3D volume into a plurality of 2D slices and applying a pre-trained 2D multi-channel global convolutional network (MC-GCN) to the plurality of 2D slices until convergence. Following convergence of the 2D MC-GCN, a plurality of parameters are extracted from a first feature encoder network in the 2D MC-GCN. The plurality of parameters are transferred to a second feature encoder network in a 3D Anisotropic Hybrid Network (AH-Net). The 3D AH-Net is applied to the 3D volume to yield a probability map;. Then, using the probability map, one or more of (a) coordinates of the objects with non-maximum suppression or (b) a label map of objects of interest in the 3D volume are generated.

  • Patent number: 10499875
    Abstract: A method ascertains a time for a fresh calibration for ascertaining up-to-date calibration parameters of an x-ray device. The x-ray device has multiple degrees of freedom of movement for its recording arrangement. X-ray images of a calibration phantom are recorded for recording positions of the recording arrangement and are evaluated to ascertain the calibration parameters allowing ascertainment of geometry parameters. In multiple operating phases, situated between two calibrations, of a further x-ray device of identical design to the x-ray device, a piece of use information describing the accumulated use of the degrees of freedom of movement during the operating phase and a piece of difference information describing the difference in the calibration parameters between the calibrations delimiting the operating phase, is ascertained and used or determining the time for a fresh calibration.

  • Patent number: 10339655
    Abstract: A method automatically evaluates x-ray image data from an examination region of a patient. X-ray image data is received from the examination region. Furthermore x-ray image data is segmented and anatomical structures are detected in the individual segments. In addition reference image data that comes closest to the segmented x-ray image data is determined. This process is undertaken on the basis of a comparison of the segmented x-ray image data with reference image data from a reference database. The reference image data of the reference database has quality information relating to the image quality of the reference image data in each case. Finally a decision is made on the basis of the quality information of the established reference image data as to whether the received x-ray image data is to be retained or rejected.

  • Patent number: 10115485
    Abstract: A method for planning an examination of an examination object by a tomosynthesis machine includes: Raw data of the examination object are acquired from defined acquisition angles. An auxiliary data set is reconstructed from the raw data. Depth data are calculated based on the auxiliary data set calculating a number of projections from the perspective of a respectively defined projection center from the auxiliary data set or from the raw data. Each of the projections has a number of image points each linked with associated depth data. The projections are displayed and at least one projection is chosen. A position of an examination region of the examination object is marked therein. A real three-dimensional position of the examination region is calculated using the marked position and its depth data, and an examination path to the examination region is calculated.

  • Patent number: 10028718
    Abstract: Data of a predetermined volume portion of an object under examination is captured by an x-ray system that includes an x-ray source and a detector. The x-ray source is activated to generate x-rays that emerge from the x-ray source, radiate through the volume portion, and after radiating through, impinge on the detector. X-rays impinging on the detector are captured pixel by pixel, in order to capture the data of the predetermined volume portion. With the pixel-by-pixel capture, only a subset of all the pixels of the detector is evaluated.

  • Patent number: 9962129
    Abstract: An operating method assists a diagnosing practitioner with describing the location of a target structure in a tomosynthesis image data record of a compressed breast of a patient. The target structure is localized by a first spatial information item. The method includes: a) ascertaining a first shape information item describing at least one first, compressed breast shape in the tomosynthesis image data record, b) determining a second shape information item describing the breast in a non-compressed breast shape, from the first shape information item, c) mapping the position of the target structure from the compressed breast shape and to the non-compressed breast shape using at least the second shape information item for ascertaining a second spatial information item relating to the non-compressed breast shape, and d) transforming the second spatial information item into a pictogram information item facilitating an abstracted pictorial representation and/or describing the latter.
