Which two components make up an x-ray tube?

The correct answer identifies the two main components of an x-ray tube, which are the cathode and the anode.

The cathode is the negative electrode of the x-ray tube, and it is responsible for producing electrons through the process of thermionic emission. This is typically accomplished by heating a filament, which releases electrons that are then directed toward the anode.

The anode serves as the positive electrode and is where the actual x-ray production occurs. When the electrons emitted from the cathode collide with the anode (specifically at a designated target area), a significant amount of energy is released, which generates x-rays.

Together, these two components work in tandem to produce x-rays efficiently. The cathode generates the electrons, while the anode transforms those electrons’ kinetic energy into x-ray radiation. Understanding the function of both components is crucial for anyone working with x-ray equipment in a dental practice, as it informs practices related to radiation safety and protection.
