Consequences of dose heterogeneity on the biological efficiency of ¹⁰³Pd permanent breast seed implants.

Abstract

Brachytherapy is associated with highly heterogeneous spatial dose distributions. This heterogeneity is usually ignored when estimating the biological effective dose (BED). In addition, the heterogeneities of the medium including the tissue heterogeneity (TH) and the interseed attenuation (ISA) are also contributing to the heterogeneity of the dose… (More)
