| 1. An X-ray imaging system, comprising:
an X-ray tube including:
a cathode for emitting electrons; and
an anode configured to receive the electrons from the cathode and to generate an X-ray beam;
wherein the anode is rotatable about an axis such that rotation of the anode about the axis induces a sweeping movement of
the X-ray beam across an object under examination; and
further wherein the anode is configured to oscillate continuously about the axis between endpoints of oscillation to generate
an X-ray fan area.
