Study Notes
X-Ray Tube Components
-
Filament: A wire that heats up to generate electrons through thermionic emission, crucial for the formation of the electron beam.
-
Electron beam: A stream of electrons produced by the heated filament, which travels toward the anode to create X-rays upon interaction.
-
X-ray beam: The resultant radiation when the electron beam strikes the tungsten anode, a pivotal part of the imaging process in X-ray technology.
-
Molybdenum neck and base: Parts of the X-ray tube, where molybdenum's low atomic number helps reduce unwanted scatter radiation and enhance image quality.
-
Rotating portion (Rotor): The component that facilitates the rotation of the anode during operation, helping to evenly distribute heat and prolong the anode's life.
-
Armature: A structure within the X-ray tube that transmits the electrical energy necessary for producing the magnetic fields that facilitate the rotor's movement.
-
Stator electromagnets: Stationary magnets that induce current to create a rotating magnetic field, enabling the rotor to spin and providing efficient heat management.
-
Bearing: Supports the anode and rotor, allowing smooth rotation while minimizing friction, which is essential for maintaining operational efficiency and longevity.
-
Tungsten anode: The target for the electron beam, tungsten's high melting point and atomic number make it ideal for X-ray production due to its efficient X-ray emission.
-
Envelope: A glass or metal container that houses the X-ray tube components, creating a vacuum to prevent electron collisions with air and improving the tube's efficiency and performance.
-
Filament circuit: An electrical circuit that powers the filament, enabling it to heat up and emit electrons, thus initiating the X-ray production process.
