Optimum Radiographic Image Quality Is a Function of Proper Exposure $\times$

question 2

Multiple Choice

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
This is known as

• A) the inverse square law.
• B) the kVp/mAs ratio.
• C) mA/mAs proportionality.
• D) mAs reciprocity.
