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

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?

The 15% rule should NOT be used in which of the following circumstances:

The length of the x-ray exposure is determined by the:

If you want a 10 mAs exposure and have selected the 50 mA station, what time in seconds is needed to produce the desired mAs? (Use decimal notation, and a leading zero if necessary.)

With all other factors unchanged, if mAs is increased by 50%, subject contrast in the remnant beam will:

Receptor exposure and mAs have what relationship

When kVp is decreased by 15%, how should mAs be changed in order to maintain the same overall receptor exposure?

To obtain 20 mAs using the 400 mA station, use an exposure time of         second:

Which of the following statements describes the relationship between kilovoltage peak (kVp) and beam intensity?
