Abstract
The concept of field equivalence for electron beams is examined using a pencil beam theory applied to circular fields. It is shown that a circular field can be found for a field of any size, shape and energy for which the depth dose distribution is approximately equivalent. The usefulness of the concept in clinical dosimetry is discussed.
