| 摘要 |
The present invention relates to an x-ray tube that utilizes a stationary anode assembly. The stationary anode assembly includes an anode target portion that is disposed on the target end of an anode substrate. The anode target includes an overhang portion, that functions to prevent rebounding electrons from striking the underlying anode substrate that would otherwise result in the production of errant x-rays, and that also functions to block errant x-rays produced at the substrate from exiting the x-ray tube. Embodiments also include an anode target having a target surface that is formed with a contoured shape that functions to direct any rebounding electrons towards the center of the anode target surface, and away from the underlying anode substrate. The present invention is particularly useful in preventing a secondary electron stream from emitting errant x-rays that would compromise the particular quality of the x-ray that the x-ray device is designed to generate.
