Detailed explanation-1: -Adopting rectangular collimation assists in not only reducing patient radiation exposure, but also in obtaining quality images that lead to improved diagnoses and treatments.
Detailed explanation-2: -Collimation and Contrast As collimation increases, the quantity of scatter radiation decreases and radiographic contrast increases; as collimation decreases, the quantity of scatter radiation increases and radiographic contrast decreases.
Detailed explanation-3: -Proper collimation is one of the aspects of optimising the radiographic imaging technique. It prevents unnecessary exposure of anatomy outside the area of interest, and it also improves image quality by producing less scatter radiation from these areas.
Detailed explanation-4: -The radiation dose reduction ranged from 40% to 92% compared with circular collimation.
