Question

Quizplus · Accepted Answer

The mA (milliamperage) setting controls the amount of current sent through the x-ray tube, which ultimately controls the amount of radiation produced. By varying the mA, the radiographer can adjust the intensity or strength of the primary beam. Time and distance settings are fixed for a given CT scan protocol, while kVp (kilovoltage peak) settings primarily affect image contrast rather than beam intensity.
