Abstract

Predictive thermometry, utilizing minimally invasive sampling techniques is an essential ingredient in the development of hyperthermia treatment planning capabilities. The authors demonstrate a powerful, but simple approach toward predicting temperature distributions in tissues, based on an analytic solution in cylindrical symmetry of the heat diffusion equation. Conduction and localized perfusion effects are combined as an effective conductivity term, readily measureable, and parameterized in a general exponential form. The utility and strength of this approach is that it provides a rapid, accurate method of directly observing the technical quality to be expected for different heating methods, enabling one to optimally configure source distributions in a treatment planning setting.
