Abstract: Extra-oral dental method and/or apparatus embodiments according to this application can generate cephalometric imaged by digital tomo synthesis. An extra-oral dental imaging system embodiment for creating a cephalometric image of at least part of a human skull can include an X-ray source, an imaging device suitable for producing multiple frames during at least part of an exposure; a memory for registering and/or storing said multiple frames; 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 object. The imaging device has an active area having a long dimension m and a short dimension n, wherein the aspect ratio m:n is strictly inferior to 1.5.

Abstract: The present invention provides an intraoral X-ray system comprising: an X-ray source located in an environment; a robotic arm comprising an actuatable scissor arm, the robotic arm having a first end configured to be attached to a mounting and a second end attached to the X-ray source, at least one of the first and the second ends comprising a rotatable actuatable joint; a position sensor to determine variation of position and/or orientation of the environment with respect to the X-ray source and variation of position and/or orientation of a mobile X-ray sensor with respect to the X-ray source; and a driving unit actuating the robotic arm as a function of the determined variation of position and/or orientation to control the position and/or orientation of the X-ray source with respect to a predetermined position and/or orientation of the X-ray source.

Abstract: The present disclosure describes methods for calibrating a spectral X-ray system to perform material decomposition with a single scan of an energy discriminating detector or with a single scan at each used X-ray spectrum. The methods may include material pathlengths exceeding the size of the volume reconstructable by the system. Example embodiments include physical and matching calibration phantoms. The physical calibration phantom is used to measure the attenuation of X-rays passing therethrough with all combinations of pathlengths through the calibration's basis materials. The matching digital calibration phantom is registered with the physical calibration phantom and is used to calculate the pathlength though each material for each measured attenuation value. A created data structure includes the X-ray attenuation for each X-ray spectrum or detector energy bin for all combinations of basis material pathlengths. The data structure is usable to perform a material decomposition on the X-ray projection of an imaged object.

Abstract: An intraoral tomosynthesis imaging apparatus having an intraoral detector coupled to a frame or radio-opaque marker attached to its radiation facing surface without any frame attached, wherein the frame defines a target aperture for an incident radiation beam. An enclosure seats against the target aperture and houses at least one x-ray source configured to emit a radiation beam from each of a plurality of focal points within the enclosure A collimator is disposed to form a collimated radiation beam and direct the collimated beam through the target aperture and to the detector. A geometric calibration phantom having a plurality of radio-opaque markers is disposed in the path of the collimated beam. This arrangement is modified to operate as a regular intraoral imaging device by accommodating a high-power central source at the same or different distances as other sources from the detector and displacing the phantom from the field of view.
