X-ray tube assembly can be counted as khan of the Galactic x-ray source with the x-ray. The x-ray tube is relying in part on the work of the TA principle of Thermionic emission is the x-ray tube, the filling is hot, burning, there will be an electronic khotron were very much on the filling tube, x-ray. When the x-ray tube voltage is sufficiently, and electronic khotron will be accelerated to high speed run to the metal target. (Anode Anode) TA metal with atomic number khotron is going to smash a high electronic atoms of the metal that is annulled x-ray occurs. X-ray tube type, which can be divided according to the characteristics of Anode plate 2.

X-ray tubes is a significant component of the CT because the X-ray is used as the origin. The operation of the X-ray tube to the principle Thermionic emission tomography filament is burned to heat the electrons occurs in a large number of X-ray tubes. When the X-ray tube voltage, the electrons are then accelerated to a high speed run to the metal targets (terminal Anode) is made of metal with a high atomic number. Electrons to the metal atoms of the target, causing radiation. Which can be classified according to the nature of the X-ray tube Anode plate has two types.

The X-ray tube is of importance component of X-ray radiation source because it has to check structure x Work of the X-ray tube will be based on the principles of Thermionic emission.When a voltage to the X-ray tube and the electrons are accelerated to high speed running part is a metal target (polarity Anode) painted metal with atomic number high. Electron will hit the atoms of the metal target paint to X-ray.Anode has 2 model.
