When using a variable kVp chart the general rule for each 1 centimeter increase in patient thickness is to:

When you change the collimation from a 14″ X 17″ to an 8″ X 10″ field size, what is the net effect on the Exposure Index with all other factors remaining constant?

Using conventional imaging, what is the minimum percentage change in mAs required to produce a noticeable change in receptor exposure?

Calculate the exposure time given 20 mAs, 400 mA.
