The Effect of Inhomogeneities on Dose Distributions of High‐energy Electrons

Clinical electron‐beam dosimetry: Report of AAPM Radiation Therapy Committee Task Group No. 25

“…The problem of tissue heterogeneities is one of the major challenges of electron-beam dosimetry. Several investigators have reported the effect of heterogeneities on dose distribu- tion for electron beams Boone et al, 1967;Almond et al, 1967;Brenner et al, 1969;Pohlit, 1969). These studies showed that the magnitude of the dose perturbation depends on the shape, size, electron density (number of electrons/cm 3 ), and the effective atomic number of the heterogeneity.…”

“…Several investigators have studied the effect of air heterogeneity on dose (Brenner et al, 1969;ICRU, 1984;Pohlit, 1969). For example, calculations by Hogstrom (1983) illustrate in Fig.…”

Physical Measurements of Medical Electron Beams–A Review

“…Bibliographies of thermoluminescence dosimetry have been published by Lin and Cameron (1 968) and Spurny (1 969). The use of TLD for measurements in high energy electron beams has been described by Almond, Wright Boone, Almond and Wright (1969) ;Brenner, Karjalainen, Rytila and Jungar (1969) ; and Dahler, Baker and Laughlin (1969). TLD, principally using LiF in powder, solid, or Teflon-embedded form, has been used mostly for measurement of dose distributions and for measurements in patients during treatments.…”
