Abstract:
1. An x-ray generating device for scanning an object under inspection, the x-ray generating device comprising: (a) at least one addressable field emission cathode, the cathode comprising a substrate and a nanostructure-containing material comprising a plurality of individually controllable nanostructure-containing elements configured to emit electrons; (b) at least one anode target comprising a plurality of focal spots corresponding to the plurality of nanostructure-containing elements, wherein the device is configured for simultaneously generating multiple x-ray beams from the focal spots at different radiation angles for simultaneous convergence at an image plane for imaging of an object; and (c) wherein the at least one addressable field-emission cathode and the at least one anode target are contained within a vacuum chamber.
