The X-Ray Tube

These flashcards cover key vocabulary related to the X-ray tube, its components, and functions, aiding in the review of the lecture notes.

X-Ray Tube

An apparatus used to produce X-rays, consisting of a cathode and an anode.

Filament

A coil of thoriated tungsten that produces electrons when heated to thermionic emission.

Thermionic Emission

The release of electrons from a heated filament.

Cathode Assembly

Contains the filament(s) and focusing cup, responsible for producing the electron beam.

Focusing Cup

A component that directs the electron beam towards the anode, usually negatively charged.

Anode Assembly

Part of the X-ray tube that serves as the target for electrons, conducts high voltage, and dissipates heat.

Rotating Anode

An anode that spins to distribute heat and improve X-ray production.

Line Focus Principle

A method used to create a smaller effective focal spot for improved image quality.

Anode Heat Loading

The ability of the anode to withstand and dissipate heat generated during X-ray production.

Leakage Radiation

Radiation that escapes from the tube housing due to failure of shielded materials.
