Multiple grooved X-ray generator |
摘要 |
An X-ray tube has a metal-ceramic envelope having rotatably mounted therein an anode disk, which may be axially translatable and provided with a peripheral rim surface wherein a focal track spiral groove (or multiple annular grooves) is disposed. The groove(s) include a focal spot(s) area spaced from an electron emitting cathode(s), which is associated with a beam-forming structure and an X-ray transparent window mounted within an insulating structure aligned with the focal spot area. The insulating structure incorporates a multiplicity of imbedded annular electrodes which control an accelerating electric field, and which are structurally and operationally integrated into a power-control assembly that provides the electrical power and control signals necessary for the functioning of the X-ray tube.
