  • 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.

  • Publication number: 20200250820
    Abstract: A method for segmenting metal objects in projection images acquired using different projection geometries is provided. Each projection image shows a region of interest. A three-dimensional x-ray image is reconstructed from the projection images in the region of interest. A trained artificial intelligence segmentation algorithm is used to calculate first binary metal masks for each projection image. A three-dimensional intermediate data set of a reconstruction region that is larger than the region of interest is reconstructed by determining, for each voxel of the intermediate data set, as a metal value, a number of first binary metal masks showing metal in a pixel associated with a ray crossing the voxel. A three-dimensional binary metal mask is determined. Second binary metal masks are determined for each projection image by forward projecting the three-dimensional binary metal mask using the respective projection geometries.

  • 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.

  • Publication number: 20200010358
    Abstract: The present invention relates to glasses having a composition made up of base glasses. The glasses have a good chemical toughenability in combination with an advantageous coefficient of thermal expansion. Owing to their composition and the production process, the homogeneity of the properties of the glasses at their surface is high compared to the bulk glass. Furthermore, the fragility of the glasses is low, so that they can be processed to produce very thin glass articles.

  • Patent number: 10376335
    Abstract: In a method and an apparatus to provide updated images during a robotically-implemented surgical procedure, 3D data is obtained of a volume of a patient, which includes anatomy involved in the procedure. The anatomy is segmented from a reconstructed image of the volume. During the procedure, the surgeon applies forces on the anatomy, causing a geometric change of the anatomy. Force sensors in the surgical robot detect these forces, which are supplied to a processor that controls display of the segmented anatomy at a display screen. From the applied forces and the physical properties of the anatomy, the processor calculates the geometric change of the anatomy that has occurred and modifies the appearance and/or position of the displayed segmented anatomy on the display screen in real time during the procedure, so as to visualize the geometric change.

  • Publication number: 20180338804
    Abstract: A system and method of registration between devices includes a tracking system and a controller. The system is configured to couple to a first device and a second arm separate from the first device. The first device has a first arm configured to couple to a manipulatable device. The second arm is configured to couple to an imaging device. The controller is configured to determine, based on tracking data from the tracking system, a first pose of the first arm and a second pose of the second arm; send a movement command to the second arm that directs the second arm to move into a third pose while maintaining a safety margin between the first and second arms. In the third pose the imaging device can capture an image of at least a portion of the manipulatable device. The movement command is based on the first and second poses.

    Abstract: A method for correction of movement artifacts in a computed tomography image that is reconstructed from a plurality of computed tomography projection images is provided. Using all projection images of the plurality of computed tomography projection images, an average position of an examination area of an examination object in the reconstructed image volume is determined by a global optimization method. With the aid of the at least one image volume block that is formed from predeterminable projection images, the movement of the examination area of the examination object in the at least one image volume block is estimated by an optimization method. A corresponding device for correction of movement artifacts in a computed tomography image is also provided.
