Patent number: 10405813Abstract: 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.Type: GrantFiled: February 4, 2015Date of Patent: September 10, 2019Assignees: Dental Imaging Technologies Corporation, PaloDEx Group OYInventors: Petri Jouhikainen, David Albert Sebok, Bradley S. Carlson, Hongjian Shi, Mike Parma, Edward Marandola, Robert Keating, Esa Suuronen, Scott Kravis

Publication number: 20190231285Abstract: 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.Type: ApplicationFiled: January 24, 2019Publication date: August 1, 2019Inventors: Sami VARTIAINEN, Petri JOUHIKAINEN

Patent number: 9770217Abstract: 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.Type: GrantFiled: January 30, 2015Date of Patent: September 26, 2017Assignees: Dental Imaging Technologies Corporation, PaloDEx Group OYInventors: Joonas Erik Sandholm, Matti Petri Jouhikainen, Robert Frank Dillon

Patent number: 7308295Abstract: 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.Type: GrantFiled: April 16, 2002Date of Patent: December 11, 2007Assignee: Instrumentarium CorporationInventors: Timo Ihamäki, Petri Jouhikainen

Patent number: 7212606Abstract: 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.Type: GrantFiled: July 13, 2005Date of Patent: May 1, 2007Assignee: General Electric CompanyInventors: Henri Souchay, Rémy Klausz, Matti Petri Jouhikainen
