WebEffective mAs is used only in CT. It is not seen in radiography or fluoroscopy. Effective mAs was introduced because in many cases the table advance in CT is not the same as the total nominal beam width. Thus, the pitch is calculated as follows: Pitch = table travel per gantry rotation (mm) / total nominal beam width, or Web24 Cards in this Set. As distance increases, rad dose decreases. If the distance from the x-ray doubles, the rad dose is 1/4 of original dose. If the distance from the x-ray tube gets cut by 1/2, the rad dose is 4 times more. At 36" SID, the rad dose in air is 100 R.
