  • Patent number: 10842456
    Abstract: A method for determining an alignment between at least two bone parts of an elongated bone system of a patient includes recording a plurality of partially spatially overlapping projection images by a recording system of an x-ray device during a translational movement of the x-ray device or the recording system in a direction of or parallel to a longitudinal axis of the bone system. Tomosynthesis image data of the bone parts is reconstructed from the recorded projection images, and an alignment angle between the at least two bone parts is determined or estimated at least partially based on the reconstructed tomosynthesis image data and/or the plurality of projection images.

  • Publication number: 20200320755
    Abstract: A method for establishing a three-dimensional tomosynthesis data record of a target volume from two-dimensional projection images recorded with a recording arrangement including an X-ray source and an X-ray detector in different recording geometries is provided. During or after a reconstruction step, a deconvolution technique is used for reducing image artifacts of the tomosynthesis data record occurring due to lacking information. The projection images are recorded along a linear recording trajectory of the X-ray source. The reconstruction and the use of the deconvolution technique take place in a plurality of different two-dimensional reconstruction planes that are spanned by the recording trajectory and, in each case, a definition point in the target volume.

  • Publication number: 20200305832
    Abstract: A method for increasing accuracy of positioning an X-ray device relative to an examination subject using a camera system includes recording a first data set, acquiring original positioning information pertaining to the X-ray device and specifying a target position of the X-ray device relative to the original position. The X-ray device is positioned out of the original position into a first approach position using the original positioning information, and a second data set is recorded. A deviation between the target position and the first approach position is determined by a reconciliation between the first data set and the second data set. The X-ray device is positioned out of the first approach position into a second approach position using the determined deviation.

  • Publication number: 20200268334
    Abstract: The disclosure relates to a method for recording a panorama dataset of an examination object by a movable medical x-ray device, to a medical x-ray device, and to a computer program product for carrying out the method. The medical x-ray device has an x-ray source, which emits a bundle of x-rays, wherein a first image segment, which maps at least one part of the examination object, is recorded at a first point in time. Position data is acquired, which maps the spatial position of the x-ray device at this first point in time. At least one further image segment along an imaging path is recorded after there has been a movement of the x-ray device, wherein the imaging path lies in one plane, wherein a central ray of the bundle of x-rays emitted by the x-ray source does not run in parallel to the plane in which the imaging path lies. Additionally, position data is acquired, which maps the spatial position of the x-ray device at the time of the recording of the at least one further image segment.

  • Patent number: 10687900
    Abstract: In a method of image support for a person carrying out a minimally invasive procedure with an instrument in a procedure site of a patient, one two-dimensional X-ray image respectively of the procedure site is recorded by an X-ray apparatus in at least two recording geometries implementing different projection directions and chosen specific to the procedure, in particular by the person. A three-dimensional model data set of the procedure region is reconstructed by iterative reconstruction from the X-ray images. At least one two-dimensional supporting image corresponding to one of the recording geometries is determined by incorporating at least one item of further information by re-projection of the model data set supplemented by the further information and is displayed for the user.

  • Publication number: 20200113534
    Abstract: Evaluating a reliability of a computed tomography (CT) volume image includes acquiring a first CT volume image and a modified CT volume image that are reconstructed from scanned projection images. From the first CT volume image and the modified CT volume image, digitally reconstructed X-ray images are then calculated. A respective similarity with a corresponding one of the scanned projection images is then determined. Based on a comparison of these similarities with one another, a reliability of the CT volume images is then evaluated.

  • Patent number: 10368946
    Abstract: A method for determining the location, in a coordinate system, of a target position for an invasive medical procedure on a patient. An entry mark that defines the coordinate system and indicates an entry position for the procedure is affixed to the patient. A site marker, which can be identified in a radioscopy image, is fixed in a known relative location in the coordinate system. At least two 2D radioscopy images of the patient, which both depict the respective site marker and the target position, are recorded from different recording directions. The location of the target position in the coordinate system is determined from the representation of the target position and from the representation of the site marker in the 2D radioscopy images and from the relative location of the site marker in the coordinate system.

    Abstract: A navigation aid for introducing an elongate medical penetration element into a patient. An X-ray image, containing a target region for the penetration element in a desired target position in a patient, is superimposed in alignment with video sequence images, containing at least in part the penetration element, to form a combination image sequence. The penetration element is captured in a start position and a desired penetration course of the penetration element at least to the target region of the penetration element in a desired target position, is visually displayed in the combination image sequence. A penetration element, such as a medical implant and/or instrument, in particular a K-wire (Kirschner wire), may carry a number of markers, such as additional bodies, coatings, elevations, and/or depressions, said markers altering a light reflection, are situated on and/or at and/or in the penetration element.

  • Patent number: 10165998
    Abstract: A method and a system for determining an angle between two parts of a bone that are twisted relative to one another about the axis of a bone shaft. The system is particularly suitable for determining the antetorsion angle of a femur. In order to determine an antetorsion angle of a bone easily intraoperatively, a method with the following steps is proposed: establishing the position of a first orientation feature assigned to a first part of the bone, in particular a femoral neck axis, using an imaging method, establishing the position of a second orientation feature assigned to a second part of the bone, in particular a condyle tangent or a condyle plane, using an imaging method, and determining the angle, in particular the femoral antetorsion angle, from the positions of the two orientation features.
