X-ray tubes that have a reduced exposure time for dental X-ray imaging and 3D dental imaging systems using these X-ray tubes are described. The X-ray tubes contain an anode, a filament, a cathode electrically connected to the filament, and a voltage source electrically connected to the cathode. The voltage source provides a high voltage to the anode relative to the cathode and filament control voltage. A low filament control voltage is used to generate electrons using a process of thermionic emission. These electrons are driven by a large electric field generated between the cathode and anode towards the target on the anode. A bias voltage is applied between the cathode and the filament to control the electron flow from the emitting filament to the anode. Such a configuration yields a switching speed ranging from about 1 ms to about 10 ms, allowing a short X-ray exposure time and a quicker overall imaging process for the 3D dental X-ray imaging systems. Other embodiments are described.
