  • 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: 20200268242
    Abstract: In order to improve the detectability of a structure that is tube-shaped in an imaging method, a method for preparing the structure is specified. A first channel is formed inside an inner wall of an auxiliary device, and a second channel is formed between the inner wall and an outer wall. A first fluid that contains a material for contrast amplification is poured into the structure via the first channel. The first channel is then closed by a swelling element of the auxiliary device being enlarged by pouring a second fluid into the second channel.

  • Publication number: 20200229879
    Abstract: The disclosure relates to a medical engineering robot, a medical system, a method for operation thereof, a corresponding computer program, and a corresponding computer-readable storage medium. By controlling a pose of an instrument arm of the robot relative to a respective examination object to be treated or to be examined by the robot, the disclosure makes provision for automatically bringing the instrument arm into contact with the examination object and through this for setting a predetermined pose of the examination object.

  • Publication number: 20200219254
    Abstract: A medical imaging device, a system, and a method for generating a motion-compensated image are provided. A corresponding method as well as a computer readable storage medium having stored thereon a corresponding computer program are also provided. Image data is captured and acquired while a deformable robotic instrument is in contact with a subject to be imaged. A data processor is configured to compensate for a motion of the subject by processing the image data in dependence on time-resolved motion and/or geometry data of the robotic instrument, and/or by generating a control signal for controlling the robotic instrument to counteract the motion of the subject.

  • Publication number: 20200219253
    Abstract: A medical assistance device, a system, and a method are provided for determining a deformation of a subject. Undisturbed image data of the subject and pose data of a robotic instrument are acquired. The medical assistance device is configured to determine the deformation of the subject due to a physical contact between the subject and the robotic instrument based on a biomechanical model. The undisturbed image data and a pose and/or motion of the robotic instrument are provided as input to the biomechanical model. The biomechanical model is predetermined or generated and/or updated based on a strain and/or a stiffness measured by a sensor.

  • Patent number: 10706546
    Abstract: A method is provided for operating a medical imaging device when performing an imaging examination. In order to allow an improved preparation of images in the context of such an imaging examination, the method includes: providing an original image of a body region; recording an updated image of the body region; and generating a three-dimensional subsequent image from the original image and from the updated image using a previously trained artificial neural network.

  • 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.
