Which beam parameter primarily controls beam quality and penetrating power?

Beam energy, or beam quality, is determined mainly by the kilovoltage setting. Raising kVp increases the average energy of the x-ray photons, allowing more of them to penetrate through tissue and reach the image receptor. That higher energy translates to greater penetrating power. Filtration also raises average energy by removing low-energy photons, but it’s a secondary modifier compared to the primary role of kVp. Distance from the source and milliamperage mainly affect how many photons are produced or reach the receptor (dose/exposure), not their energy. So the parameter that best controls both beam quality and penetrating power is kilovoltage.
