Claim 16:
17. A cone beam extra-oral dental imaging system for creating a cephalometric image of at least part of a human skull without the use of a cephalometric arm and without superposition of images, said system comprising:
an X-ray source configured to produce an x-ray beam having a cone shape and to irradiate a human skull to be imaged;
an imaging device suitable for producing multiple frames during at least part of an exposure of said human skull, said imaging device being located relative to said X-ray source at a location normally used for producing panoramic images or computed tomography images; and
a manipulator for displacing the imaging device along an exposure profile between multiple frames during said at least part of the exposure of said human skull, the manipulator permitting the movement of the X-ray source and the imaging device in unison by selective translation and selective rotation,
wherein said imaging device has an active area having a long dimension m and a short dimension n, wherein the aspect ratio m:n is less than 1.5;
wherein said manipulator synchronously displaces the X-ray source and the imaging device along said exposure profile, said exposure profile comprising at least one substantially linear section wherein said X-ray source and said imaging device are translated while rotating in the same direction; and
wherein said imaging system is configured to produce the cephalographic image from multiple frames captured from the active area during the displacement of the X-ray source and the imaging device along said exposure profile.
