Rectifiers are used to convert alternating current to direct current in the X-ray system. They are part of which component?

• A. Anode assembly
• B. Cathode assembly
• C. High-voltage generator
• D. Filtration system

Answer: (C)

Rectification is needed to supply the X-ray tube with direct current so electrons flow in one direction from the cathode to the anode. This happens inside the high-voltage generator, which includes the transformer steps up the line voltage and the rectifiers that convert the alternating current to direct current for the tube. The anode assembly is the high-voltage target where X-rays are produced, while the cathode assembly supplies the heated filament electrons; the filtration system removes low-energy photons. Because the tube must receive stable, unidirectional current to function properly and avoid reversing polarity, the rectifiers belong in the high-voltage generator.
