(a) The influence of the energy spread of incident electrons on PDDs for 10 × 10 cm² field. (b) The influence of energy spread of incident electron on OARs for 10 × 10 cm² field at 10 cm depth. Red curve represents the dose curve when the energy spread is 5%, the green curve represents the dose curve when the angular divergency is 20%, and the black curve represents the measured dose curve.
