Abstract
An x-ray system includes x-ray tube containing a cathode which supplies electrons and an anode which can be maintained at high positive electrical potential to the cathode and has a target area which is impacted by electrons from the cathode when the positive potential is maintained generating x-rays. The x-ray tube is enclosed in a radiation resistant casing. The radiation resistant casing has a window which allows some of the x-rays generated at the target area to exit the system. The window has a vapor deposited layer of a filtering metal of sufficient thickness to effectively condition the x-rays passing through the window and located to intercept the x-rays passing through the window.
