  • Publication number: 20200375563
    Abstract: The disclosure relates to a method for creating a three-dimensional digital subtraction angiography image of a vascular system of a patient. The method includes: providing a first reconstructed three-dimensional filling image which was acquired during at least partial contrast agent filling of the vascular system with a first contrast agent; providing a second reconstructed three-dimensional filling image which was acquired during at least partial contrast agent filling of the vascular system with a second contrast agent; and subtracting the first three-dimensional filling image from the second three-dimensional filling image so that a three-dimensional subtraction angiography image is produced, wherein the first contrast agent and the second contrast agent differ in that one of the two causes increased X-ray absorption and the other causes reduced X-ray absorption relative to a vascular system without contrast agent.

  • Patent number: 10842484
    Abstract: A surgical staple has two movable arms connected by a transverse connection area. Each one of the arms has a pinching area and a fastening end and the transverse connection area is deformable to allow the movable arms to be moved together by bending around the axis of the transverse connection area.

  • Publication number: 20200352592
    Abstract: A positioning unit for guiding a medical object such as a needle includes a securing unit by which the positioning unit may be arranged on the medical object. In order to enable an improved guidance for the medical object, an indicating element with a plurality of indicators is provided. The indicating element is arranged in a fixed position relative to the securing unit. An acquisition unit acquires an item of movement information. The positioning unit is configured to control the plurality of indicators dependent upon the movement information.

  • Publication number: 20200315736
    Abstract: A guide unit for guiding a medical object such as a needle includes a locking unit, by which the guide unit may be disposed on the medical object. In order to enable a position of a medical object to be precisely determined, an aligning element that is in a fixed pose relative to the locking unit is provided. A contour that has a higher radiopacity than a remainder of the aligning element is disposed on the aligning element.

  • Publication number: 20200250835
    Abstract: An imaging device and a method for generating a motion-compensated image or video are provided. The imaging device has a data acquisition facility for acquiring image data of a target object. The imaging device is configured to acquire, using a registration facility, a posture of an inertial measurement unit and, on the basis thereof, to carry out a registration between coordinate systems of the inertial measurement unit and the image data. The imaging device is further configured to acquire motion data from the inertial measurement unit arranged on the target object and, by processing the motion data, to generate the motion-compensated image or video.

  • Publication number: 20200234449
    Abstract: The disclosure relates to a medical imaging device, a method for supporting medical personnel, a corresponding computer program product, and a corresponding computer-readable storage medium. In the method, a 3D data record is received from a first imaging modality and image data of an examination object is received from a second imaging modality. Different tissue regions of the same organ are imaged with different imaging properties at least under the second imaging modality. A tissue boundary is detected between the tissue regions in the image data. For registration of the image data with the 3D data record, the tissue boundary is aligned at a corresponding tissue boundary in the 3D data record. In addition, or alternatively, based on the tissue boundary, an automatic movement compensation takes place of a movement of the examination object which has occurred during the generation of the image data.

  • Publication number: 20200085527
    Abstract: An improved guide for a medical needle is disclosed herein. An aligning element for aligning a needle guide, which is equipped for longitudinally guiding a medical needle, includes a connecting element for arranging the aligning element on the needle guide, and a light-guiding element for a predetermined diffusion of light. The light-guiding element only generates a predetermined light pattern relative to the diffusion of light in a pose predetermined by the geometry of the apparatus. Such an aligning element may be used in a treatment arrangement for longitudinally guiding a needle and in a method for aligning a needle guide.

  • Publication number: 20200036910
    Abstract: A camera image is acquired by a camera and a structure that is optically concealed in the camera image is acquired by a material-penetrating acquisition modality. A stereoscopic depth location of a common reference point is then fixed at a predetermined value. The stereoscopic representation is then generated from the camera image, and an overlay image is generated based on the concealed structure. In this case, a depth location of the camera image is fixed at the depth location of the reference point, and, as a function thereof, a depth location of the overlay image is adjusted in relation to the depth location of the reference point, such that in the stereoscopic representation, the overlay image appears realistically in front of and/or behind an optically opaque part in the recording direction of the camera image.
