X-Ray Tube

What are the two main components of an x-ray tube?

• Filament and Rotor

• Cathode and Anode

• Stator and Bearing

• Glass Envelope and Housing

What is the primary function of the cathode in an x-ray tube?

• To produce a thermionic cloud

• To serve as a target for electrons

• To dissipate heat

• To support the x-ray tube

Which material is commonly used for the target anode in x-ray tubes?

• Copper

• Aluminum

• Tungsten

• Lead

The purpose of the glass envelope in an x-ray tube is to provide

• radiation and electrical protection.

• electrical and thermal protection.

• electrical, thermal and physical protection.

• electrical, thermal, physical and radiation protection.

The physical area of the focal track that is impacted by the electrons is called

• actual focal spot

• effective focal spot

The primary undesirable product generated by the x-ray tube is

• X-rays

• Heat

• Radiation

• Electrons

The function of the focusing cup in the cathode is

• To support the anode

• To produce x-rays

• To focus the electron stream

• To dissipate heat

Which type of anode is most commonly used in modern radiography equipment?

• Rotating anode

• Dual-focus anode

• Fixed anode

• Stationary anode

What is the purpose of the line-focus principle?

• To increase the size of the focal spot and enhance image quality

• To decrease the effective focal spot size while reducing the heat

• To enhance radiation protection

• To improve electrical insulation

What is the primary role of the anode in an x-ray tube?

• To conduct high voltage

• To generate heat

• To produce thermionic emission

• To serve as a target for electrons
