title: Film dosimetry for shaped electron fields.
abstract: The key to successful electron beam treatment planning is to realize that an electron beam does not behave like a photon beam, and that each electron field is unique and should be treated as such. Film dosimetry provides an efficient and accurate method of determining electron dose distributions for a particular field when compared to the cumbersome, time-consuming ion chamber in tissue equivalent material, thermoluminescent dosimeters (TLDs), or complex equivalent square calculations.
