Two exposures are made using the following technical factors: Image A: 500 mA,0.05 seconds,72 kVp
Image B: 200 mA,0.125 seconds,72 kVp
Which image would have the greater density?

Question

Quizplus · Accepted Answer

Both images have the same mAs (milliampere-seconds) value, which is the product of mA and exposure time. Image A has 500 mA * 0.05 s = 25 mAs, and Image B has 200 mA * 0.125 s = 25 mAs. Since the mAs and kVp are the same for both images, they would exhibit equal density.
