Imaging Questions and Answers
What type of relationship do mAs have with the quantity of x-rays produced?
a. direct proportional
b. direct but not proportional
c. inverse proportional
d. inverse but not proportional - Correct Answers -direct proportional
How much mAs is produced when the mA is 200 and the exposure time is 0.5 s?
a. 25 mAs
b. 50 mAs
c. 100 mAs
d. 200 mAs - Correct Answers -100 mAs

Which of the following has an effect on how much mAs is used for a specific
examination?

If a film image has sufficient but not optimal density:
a. it should not be repeated
