What limits the irradiated volume and reduces undercutting?
A) scatter
B) saturation
C) collimation
D) overexposure

Question

Quizplus · Accepted Answer

Collimation refers to the restriction of the size and shape of the radiation beam to the area of interest. By limiting the irradiated volume, collimation reduces the amount of scatter radiation and minimizes undercutting of the adjacent healthy tissues. Saturation and overexposure refer to the amount of radiation delivered, and scattering refers to the dispersion of the radiation beam, which can contribute to increased doses to healthy tissues.
