Publication number: 20250288197Abstract: The invention relates to a device for data acquisition. The device includes an arrangement, wherein the arrangement can be positioned or received such that at least one end section of the arrangement projects into a cavity, and wherein at least one section of the arrangement is subjected to pressure when the arrangement is positioned such that at least the end section of the arrangement projects into the cavity; and at least one acquisition unit, which is configured and arranged on the arrangement to perform at least one data acquisition of at least a portion of the cavity.Type: ApplicationFiled: March 7, 2025Publication date: September 18, 2025Applicant: DÜRR DENTAL SEInventor: Wolf BLECHER

Patent number: 12263023Abstract: A 3D X-ray device including an X-ray detector, an X-ray source and a computer. The X-ray detector and the X-ray source are moved about an object volume to be recorded on movement paths with a rotation of at least 185°. A number of X-ray projection images are recorded from different directions. X-rays irradiate the object volume in one of the irradiation directions and are captured by the detector. A 3D X-ray image of the object volume is calculated from the recorded X-ray projection images by a reconstruction method. The X-ray detector is arranged asymmetrically relative to a central axis through a center of rotation of the 3D X-ray device. A first fan beam and an opposite second fan beam rotated 180° form an overlap region. At least one X-ray filter is placed between the X-ray source and the object volume for attenuating an X-ray dose inside the overlap region.Type: GrantFiled: November 27, 2020Date of Patent: April 1, 2025Assignee: Dentsply Sirona Inc.Inventors: Johannes Ulrici, Kai Stannigel, Wolf Blecher
