1. A dental imaging apparatus, which apparatus includes
a support construction (11, 13) for supporting a structure supporting imaging means (14), at least one imaging station (18) for placing a patient to the apparatus for imaging, said apparatus including at least one lighting structure (23) at the imaging station (18) to illuminate the patient's face; in which apparatus the imaging means includes at least an x-ray source (15) and a receiver module (20) including a means for receiving x-ray image information (21), which have been arranged in the apparatus in such a way with respect to said imaging station (18) that the x-ray source (15) and the means for receiving x-ray image information (21) can be positioned at opposite sides of the imaging station (18) such that a beam generated by the x-ray source (15) can be aligned to go through said imaging station (18) and towards said means for receiving x-ray image information (21), a control system for controlling operations of the imaging apparatus and a means integrated with the imaging apparatus or arranged into functional connection with it for processing information detected at the means for receiving x-ray image information (21), characterized in that the apparatus includes a means for photographing (22) a patient's face and/or for producing a moving picture of the patient's face from at least two directions while the patient is positioned at said imaging station (18), which means comprises at least one colour camera (22) the location of which with respect to said imaging station is arranged changeable and/or at least two colour cameras being arranged to image the patient's face positioned at the patient support station (18) from different directions, wherein said lighting structure (23) and at least one means for photographing (22) are arranged into connection with said structure supporting the imaging means (14), and a means arranged into functional connection with said at least one colour camera (22) for processing the image information acquired when imaging the patient's face to create a virtual three-dimensional texture model of the patient's face, and/or for combining the image information detected by said at least one colour camera (22), or the three-dimensional texture model created from it, to a surface model of the patient's face to create a virtual three-dimensional texture model of the patient's face. |
