What does mA determine in the imaging setup?

Explanation:
The rate of X-ray production is controlled by the tube current, or mA. Increasing the tube current means more electrons are flowing from the cathode to the anode per second, so more X-ray photons are produced each second. That increases the beam’s quantity (beam intensity) reaching the film. The energy or penetrating power of the beam (quality) is set by kVp, not by mA. The total exposure you deliver also depends on how long the tube is on, so the overall amount of X-rays is related to both mA and exposure time (mAs = mA × time). Film speed, meanwhile, is a property of the imaging system and does not determine how many X-rays are produced.
