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.

Abstract
An X-ray imaging system is provided which includes an X-ray tube including, a cathode for emitting electrons; and a dynamic anode. The dynamic anode receives the electrons from the cathode and generates an X-ray beam that is non-stationary. The dynamic anode rotates between a first position where the X-ray beam is directed at a first location on an object and a second position where the X-ray beam is directed at a second location on the object to generate the non-stationary beam.

8. A method for backscatter X-ray imaging, comprising:
-
in an X-ray tube, emitting electrons from a cathode; receiving the electrons from the cathode at an anode and generating an X-ray beam emanating from the anode; rotating the anode about an axis between a first position where the X-ray beam is directed at a first location on an object under examination and a second position where the X-ray beam is directed at a second location on the object, thereby inducing a sweeping movement of the X-ray beam across the object; oscillating the anode continuously about the axis between endpoints of oscillation to generate an X-ray fan area; backscattering X-rays in the X-ray beam from the object; detecting the backscattered X-rays; and generating an image of the object from the detected backscattered X-rays. - View Dependent Claims (9, 10, 11, 12, 13)
