When imaging the pelvis, changing from 14 * 17 collimation to 8 *10 collimation requires

Question

Quizplus · Accepted Answer

Changing from a larger collimation area (14x17) to a smaller one (8x10) reduces the amount of tissue irradiated, which can result in a decrease in the amount of scatter radiation produced and potentially a decrease in image brightness. To compensate for this and maintain image quality, an increase in mAs is typically required to ensure adequate exposure.
