Kilovoltage (kVp): The electrical control setting that determines the penetrating power of the x-ray beam; voltage controls the speed and power of x-ray beams; the higher the voltage, the shorter the x-ray wavelengths and the greater the energy of the x-ray beam. Milliamperage (mA): The electrical control setting that determines the amount or concentration of the x-rays by controlling how rapidly the radiation is produced; the higher the mA setting, the more x-rays are produced per second. Exposure time (in seconds [s]): The duration of the patient's x-ray exposure; most exposures are less than 1 second, so the total time a patient is exposed to the x-ray is measured in milliseconds. The amount of x-rays produced depends on the length of exposure. Source-to-image distance (SID): The distance between the x-ray tube and the film or other image receptor; the greater the distance, the more widely the x-ray beam will spread and the lower the intensity of the beam.
