Effect of scattering and differential attenuation on beam profile in the presence of high-density intensity modifying compensator

Conclusions: The presence of compensator changes photon beam mean energy along the cross-section resulted in decreased beam flatness and increased scattering. This may lead to overestimation of dose along off-axis within radiation field if change in flatness is not taken into account and more exposure to healthy tissues in penumbral region due to large-angle scattering.
