What is the main purpose of a transformer in radiography?

The main purpose of a transformer in radiography is to increase or decrease voltage, which is essential for the functioning of X-ray machines. In the context of radiography, transformers are used to adjust the voltage levels needed for the generation of X-rays.

When an X-ray machine operates, it requires high voltage to produce X-rays effectively. A transformer allows the operator to either step up (increase) the voltage from the power supply to a level suitable for X-ray production or step down (decrease) the voltage for other components in the system that may require lower levels. This ability to control voltage is critical because the quality and quantity of X-rays produced depend on the voltage supplied.

While there are other electrical components that manage current flow or convert current types, the specific role of the transformer is to handle voltage transformation, making it a fundamental aspect of how X-ray machines function correctly and safely.
