Which kVp selection would produce the greatest relative percentage of scattered radiation?

Your inital exposure is 40 mAs, 200 mA at 0.20 sec. If you want to decrease your mAs to 20 and decrease your exposure time to 0.10 sec, what mA is required?

Which of the following will give the same mAs as a 400 mA at 0.2 second exposure?

Which of the following factors does NOT affect image contrast?

An increase in the number of photons reaching the image receptor is normally associated with a/an:

When the 15% rule is used to increase contrast:

Kilovoltage peak (kVp) in the x-ray tube is the unit of measurement describing:

Adjustments in kVp should be used to control

You select an exposure of 400 mA at 1/40 sec. Your supervising technologist instruct you to change the technique to 200 mA at 1/20 sec. Will the change make a difference in the receptor exposure?

Ten kVp is considered a 15% change in which of these kVp ranges?
