Patent ID: 8837668

Claim:
A movement mechanism for an extraoral dental X-ray apparatus, which movement mechanism joins an X-ray source and an X-ray detector unit and is adapted to rotate about the subject of the imaging and comprises at least two parts turnable with respect to each other, said X-ray source and X-ray detector unit being located in different parts of the movement mechanism, wherein in the movement mechanism the positions of the X-ray source and X-ray detector unit or X-ray detector are adapted to change when said at least two parts are turned with respect to each other between a symmetrical CT imaging position and at least one offset imaging position or between different offset imaging positions so that the X-ray beam emitted by the X-ray source hits said X-ray detector unit or X-ray detector, or said X-ray detector unit is adapted to move closer to the X-ray source along the beam of the X-ray source when a part of the movement mechanism connected with the X-ray detector unit is turned into a panoramic imaging position.
