摘要

Radiographic exposure is controlled by 3 components: kVp (kilovolt peak), MA (milliamperage), and exposure time. KVp controls the "quality" of the x-ray beam. This is the power of each particular x-ray particle which controls the penetration of the beam through tissues. The quantity of the exposure is controlled by MA and time of exposure. The higher the MA, the more X-rays produced over the time period. Multiply this number by the exposure time in order to calculate the total number of x-ray units.
