  • Patent number: 10405813
    Abstract: Systems and methods for obtaining a panoramic image are provided. One system includes a gantry, an x-ray source, a receptor, and at least one controller. The x-ray source is mounted on the gantry and is configured to alternatively output x-ray radiation at a first energy level and x-ray radiation at a second energy level. The receptor is mounted on the gantry so that x-ray radiation from the x-ray source impinges on the receptor. The receptor is configured to output a plurality of frames of data including a first frame and a second frame sequential to the first frame. The controller is configured to control the x-ray source so that data in the first frame is generated based on x-ray radiation of the first energy level and data in the second frame is based on x-ray radiation of the second energy level.

  • Publication number: 20190231285
    Abstract: The application relates to a portable bite part (230) for correcting a motion of an object (201) in Panoramic, Computed Tomography, or Cephalometric X-ray imaging. The bite part comprises a first end (233) and a second end (234). The bite part has known dimensions. The first end is configured to be positioned in a mouth (202) of the object. The bite part further comprises markers (231, 232), which make possible to recognize positions of the markers from at least two images (237, 238) presenting the bite part and to calculate the motion of the object with respect to an X-ray imaging unit (100) by using the positions of the markers and the known dimensions of the bite part.

  • Patent number: 10258306
    Abstract: A method, a device, a system and a computer program are for controlling limited-area computer tomography imaging. The method includes determining location data of a first imaging object when the first imaging object is positioned in an imaging area, determining reference location data related to the first imaging object and adjusting the imaging area based on the location data of the first imaging object and said reference location data for imaging a second imaging object. The first and the second imaging object can be located at a distance determined by the reference location data from each other or symmetrically in relation to the reference location data.

  • Patent number: 9770217
    Abstract: Systems and methods are presented for evaluating a dental condition. A first digital representation of at least a portion of an oral cavity of a first patient is compared to a second digital representation of the oral cavity of the same patient. The first digital representation is representative of the oral cavity of the first patient at a first time and the second digital representation is representative of the oral cavity of the first patient at a second, later time. At least one clinically-significant difference between the first digital representation and the second digital representation are automatically identified and the first digital representation is displayed in a way that highlights the at least one clinically significant difference.

  • Patent number: 7308295
    Abstract: A mammography apparatus has a bracket having one of its arms fitted with an X-ray tube head. The X-ray tube head is formed of an X-ray tube for producing X-radiation and a collimator for collimating the X-radiation. The bracket arm opposite the X-ray tube head is fitted with an image forming element. The bracket is further provided with a compression means for compressing a breast during an imaging procedure. The image forming element has a digital full field detector. The mammography apparatus has integrable therewith a biopsy device with a biopsy needle. The detector required in a biopsy imaging process for imaging the volume space of biopsy is formed of a desired element of the full field detector. A needle guiding unit is provided for a guided movement of the biopsy needle in the volume space of biopsy on the basis of three-dimensional information compiled in the biopsy imaging process.

  • Patent number: 7212606
    Abstract: In an apparatus for radiographic projection tomography, particularly mammography, an X-ray tube is mounted at the end of a swiveling arm, with a relative movement mechanism. The relative movement mechanism is such that it enables the tube to follow a path of a cycloid. Images or exposures taken only during the time when the tube, in its path, follows cusp points such that it is possible to keep a constant speed of movement of the arm while at the same time increasing the useful duration of an image. Vibration or oscillation effects inherent in the apparatus are compensated by the positioning, if necessary, of a counterweight.
