Claim Text:
1. A tube for generating x-rays comprising: a cathode adapted to emit electrons; a target positioned to receive the electrons from the cathode on a surface thereof; an anode adapted with an aperture and positioned between the cathode and the target and configured to accelerate the electrons toward the surface of the target, wherein the anode is grounded; a rotating system adapted to rotate the target about an axis, the rotating system attached to the target and located in a position facing the surface of the target that is positioned to receive the electrons from the cathode; a high voltage insulator positioned between the cathode and the rotating system to electrically insulate the rotating system from the cathode; and an electron collector having a first aperture therein and positioned between the anode and the target; wherein the anode and the electron collector are positioned such that the electrons pass through the first aperture of the electron collector and through the aperture of the anode.
