Abstract: The present invention relates to an apparatus (20) for real-time visualizing a movement of a lower jaw (12) versus an upper jaw (14) in a craniomaxillofacial area (16) of a patient (18) in dental diagnostics, comprising: an input interface (32) for receiving a two-dimensional image signal (26) of the craniomaxillofacial area of the patient from a camera (40) and a three-dimensional jaw model (28) of the craniomaxillofacial area of the patient being precalculated based on volume data; a registration unit (34) for registering the three-dimensional jaw model with the two-dimensional image signal in a first jaw position of the lower jaw versus the upper jaw and in a second jaw position of the lower jaw versus the upper jaw; an imaging unit (36) for generating a two-dimensional depth-view (30) of the craniomaxillofacial area from the three-dimensional jaw model based on the conducted registrations and the two-dimensional image signal, said two-dimensional depth-view including a structure underlying an image area of the two-dimensional image signal; and an output interface (38) for outputting the two-dimensional depth-view. The present invention further relates to a system (10) and method for real-time visualizing a movement of a lower jaw (12) versus an upper jaw (14) in a craniomaxillofacial area (16) of a patient (18) in dental diagnostics.

Abstract: Disclosed herein is a method for creating a 3D dental X-ray image of a jaw region of a patient from a plurality of projection exposures of an exposure volume having a cylindrical core volume with a flat base area, generated during a circulation of an X-ray emitter and an X-ray detector about the head of the patient. The patient may be positioned relative to the core volume so that the jaw region is located within the core volume, and where a bottom edge of the lower jaw of the patient and the base area of the core volume are aligned at least approximately parallel.
