Which part of an x-ray machine is responsible for converting electrical energy into x-rays?

The function of converting electrical energy into x-rays is performed by the anode, which is essentially a key component within the x-ray tube. When electrons are emitted from the cathode, they travel across the tube and strike the anode. This high-speed interaction results in the production of x-ray photons.

The anode is typically made of a material with a high atomic number (like tungsten), which facilitates the efficient generation of x-rays through the process of Bremsstrahlung radiation and characteristic radiation. As the electrons collide with the anode, their kinetic energy is transformed into electromagnetic energy in the form of x-rays.

Understanding the role of each component in an x-ray machine can clarify the entire x-ray production process. The cathode is primarily responsible for electron production, the transformer adjusts voltage levels, and the control panel allows for user interface and adjustments, but it is the anode that directly converts that electrical energy into the x-rays necessary for imaging.
