Abstract
Digital tomosynthesis systems, methods, and computer readable media for intraoral dental tomosynthesis imaging are disclosed. In some aspects, an intraoral tomosynthesis imaging system includes an x-ray source array for positioning outside a mouth of a patient, wherein the x-ray source array contains multiple x-ray focal spots that are spatially distributed on an anode, an area digital x-ray detector for positioning inside the mouth of the patient, a geometry calibration mechanism for connecting the x-ray detector to the x-ray source array, an x-ray collimator for confining x-ray beams to a region of interest, a controller for regulating x-ray radiation and synchronization of the x-ray radiation with the x-ray detector, such that multiple 2D projection images of the ROI are acquired without mechanical motion of the x-ray source array, the x-ray detector, or the mouth of the patient, and a computer program and workstation for 3D tomosynthesis image reconstruction and display.
