Optimum radiographic image quality is a function of proper exposure technique selection.Given the three sets of mAs calculations that follow,all three should yield the same degree of radiographic exposure to a detector.
Exposure 1: 200 mA $\times$ 0.05 ms
Exposure 2: 100 mA $\times$ 0.10 ms
Exposure 3: 400 mA $\times$ 0.025 ms

The principle demonstrated by the given exposures is the mAs reciprocity law, which states that as long as the milliampere-seconds (mAs) value is constant, the radiographic exposure will be the same regardless of the combination of milliamperes (mA) and exposure time (seconds) used. This is evident in the provided examples, where the product of mA and time remains constant across all three exposures, indicating that they should yield the same degree of radiographic exposure.
