Abstract
Multi-modality dental x-ray imaging devices, systems, and methods. In some embodiments, an x-ray imaging system is operable in cone-beam computed tomography, two-dimensional intraoral x-ray, and intraoral tomosynthesis imaging modes. In some embodiments, the device includes a rotatable gantry, an x-ray source array attached to the rotatable gantry and including x-ray focal spots, a digital area x-ray detector attached to the rotatable gantry, an intraoral sensor, an adjustable collimation assembly positioned between the x-ray source array and the subject and configured to limit x-ray radiation to a surface of the intraoral sensor or the digital area x-ray detector depending on the selected imaging mode, and a control unit including one or more processors, the control unit configured to operate the x-ray imaging system in one of the imaging modes.
