Answer:
3 Types of Used X-ray Tubes
• a used ct tube.
• a reprocessed ct tube.
• a reloaded ct tube.
Explanation:
other possible answers :
• Crookes Tube (cold cathode tube)
generated the electrons needed to create X-rays by ionization of the residual air in the tube, instead of a heated filament, so they were partially but not completely evacuated.
• Coolidge tube (hot cathode tube)
the Coolidge tube, the electrons are produced by thermionic effect from a tungsten filament heated by an electric current. The filament is the cathode of the tube. The high voltage potential is between the cathode and the anode, the electrons are thus accelerated, and then hit the anode.
• Rotating anode tube
A considerable amount of heat is generated in the focal spot (the area where the beam of electrons coming from the cathode strike to) of a stationary anode. Rather, a rotating anode lets the electron beam sweep a larger area of the anode, thus redeeming the advantage of a higher intensity of emitted radiation, along with reduced damage to anode compared to its stationary state.
• micro-focus X-ray tube
Some X-ray examinations (such as, e.g., non-destructive testing and 3-D micro tomography) need very high-resolution images and therefore require X-ray tubes that can generate very small focal spot sizes, typically below 50 μm in diameter. These tubes are called microfocus X-ray tubes.
There are two basic types of microfocus X-ray tubes: solid-anode tubes and metal-jet-anode tubes.
