Abstract
Electron beam output (dose/MU) is generally specified at the depth of maximum dose (zmax). The location of this point depends on beam energy, field size and field shape. Useful relationships have been developed to estimate zmax as a function of field size and beam energy. The formalism uses a pencil beam theory applied to circular fields.
