Abstract: Systems and methods for digitally switching x-ray emission systems include a digital switching unit operable to selectively connect a low voltage driving circuit to activate a field emission type electron emitting construct such that electrons are accelerated by a high voltage towards an anode target thereby generating a pulse of x-rays. The x-ray pulses directed towards a scintillator are detected by an optical imager when its shutter is open. Shutter signals and the activation signals may be synchronized to produce required x-ray detection profiles.
