What key input parameters may be adjusted when generating x rays?

The key parameters are the voltage applied across the x-ray tube (measured in kilovolts [kV]), the current flowing through the x-ray tube (measured in milliamperes [mA]), and the exposure time (measured in milliseconds [ms]). The product of tube current (in mA) and exposure time (in s) can be expressed in milliampere-seconds (mAs), which is directly proportional to x-ray tube output.
