    consumption for handheld instrumentation. Areas of the tube that have been improved include the anode, the cathode, and the high-voltage power supply. 1) The anode can be a sputtered film on the inside of the X-ray window. Densified films of a more uniform thickness provide higher X-ray output and more

    detectors. Many critical medical devices are fabricated from rubbers, plastics, and ceramics. These materials have low x-ray absorption and consequently do not lend themselves to most real-time x-ray inspection methods. Such materials must be x-ray imaged with low settings of the x-ray tube anode
