Dental x-ray apparatus
A dental x-ray apparatus ( 10 ) includes a tube head ( 11 ) formed from a cast zinc material. Structural components of tube head ( 11 ) include such component ( 20 ) formed from a plastic material impregnated with a high molecular weight substance, such as barium sulfite. X-ray apparatus 10 has a control panel ( 15 ) in close proximity to the tube head ( 11 ), and is preferably DC powered.
1. A dental x-ray apparatus having an x-ray tube disposed within a tubehead and the tubehead being supported by a yoke, the yoke having a control panel to perform control operations.
2. The dental x-ray apparatus of claim 1 wherein the tubehead is formed from cast zinc or zinc alloy.
3. The dental x-ray apparatus of claim 1 wherein the tubehead comprises a plurality of components and at least one of the tubehead components is formed from a plastic material impregnated with a radiation absorber.
4. The dental x-ray apparatus of claim 3 wherein the radiation absorber is a barium compound.
5. The dental x-ray apparatus of claim 4 wherein the barium compound is barium sulfite.
6. The dental x-ray apparatus of claim 5 wherein a tubehead component is an x-ray tube holder.
7. A dental x-ray apparatus comprising:
a tubehead, the tubehead comprising a housing, a collimator, a x-ray tube, high-voltage circuitry including one or more high-voltage transformers, dielectric oil and a tube holder to support the x-ray tube, wherein the collimator, the x-ray tube, the high voltage circuitry and the tube holder are disposed in the housing and soaked in dielectric oil;
a yoke connected to the tubehead to support the tubehead;
a support structure connected to the yoke to support the yoke; and
a control panel to perform control operations, the control panel being located on one of the yoke and the tubehead.
8. The dental x-ray apparatus of claim 7 wherein the tubehead is formed from cast zinc or zinc alloy.
9. The dental x-ray apparatus of claim 7 wherein the tube holder is formed from a plastic material impregnated with a radiation absorber.
10. The dental x-ray apparatus of claim 9 wherein the radiation absorber is a barium compound.
11. The dental x-ray apparatus of claim 10 wherein the barium compound is barium sulfite.
12. The dental x-ray apparatus of claim 7 wherein the control panel is located on the yoke.
13. The dental x-ray apparatus of claim 7 wherein the control panel is located on the tubehead.
