Increased collimation results in
1) less volume of tissue irradiated
2) less exit radiation reaching the IR
3) less scatter reaching the IR

Question

Quizplus · Accepted Answer

Increased collimation reduces the volume of tissue irradiated, which in turn decreases the amount of exit radiation and scatter radiation reaching the image receptor (IR). This is because collimation limits the beam size, focusing it more precisely on the area of interest, thus reducing unnecessary exposure to surrounding tissues and reducing the overall amount of radiation produced.
