1. An x-ray intraoral tomosynthesis imaging system comprising:
an x-ray source array comprising one or more spatially distributed x-ray focal spots configured to produce a scanning x-ray beam;
a voltage power supply and a current source;
a switching circuit configured to connect the current source to a plurality of cathodes of the x-ray source array, one at a time, to produce a scanning x-ray beam;
a collimation assembly configured to provide rectangular or circular radiation fields;
a digital intraoral x-ray detector;
an input panel configured to allow a user to select one or more of x-ray energy, tube current, exposure time, and imaging mode; and
an image viewer configured to display a stack of reconstructed tomosynthesis slice images,
wherein the x-ray source array is configured to selectively produce either: (a) a scanning x-ray beam illuminating an object from different viewing angles without mechanically moving the x-ray source array for tomosynthesis; or (b) a single two dimensional (2D) radiograph; and
wherein the collimation assembly is configured to substantially collimate x-ray radiation from all x-ray focal spots to the digital intraoral x-ray detector.
