9.1 - Electron beam percentage depth dose (PDD) curves

This video provides an overview of the physics behind radiotherapy electron beam percentage depth dose curves, including:

How surface dose, the depth of maximum dose, practical range and photon contamination vary with energy.
The reasons behind the buildup effect in electron beams.
An explanation of the bremsstrahlung tail and its variation with energy.
The effect of beam energy on PDD curve shape.
Effect of field size on PDD curves, including loss of lateral electroni equilibrium.
Effect of oblique beam incidence.
Effect of variations in source to surface distance.
