Abstract
Intraoral tomosynthesis systems, methods, and computer readable media for dental imaging can include an x-ray source containing multiple focal spots spatially distributed on one or multiple anodes in an evacuated chamber, an x-ray detector for positioning inside a mouth of a patient, a device for determining imaging geometry of the intraoral tomosynthesis system; and control electronics configured to regulate the x-ray source, by sequentially activating each of the multiple focal spots, such that multiple two dimensional (2D) projection images of the mouth of the patient are acquired from multiple viewing angles. In some aspects, the device for determining the imaging geometry can comprise a plate connectedly attached to the x-ray detector, at least one light source connectedly attached to the x-ray source, and a camera configured to capture at least one light spot produced by a projection of at least one light beam onto the plate.
