Abstract

The finite-difference-time-domain (FDTD) method has been used to simulate hyperthermia treatment using the Sigma-60 applicator of the BSD-2000 Hyperthermia System. In order to use this simulation capability in treatment planning, a detailed anatomical representation of the patient must be created. The authors describe a system developed to create such models from the CT scans of the patients and to display the results of the simulation. About a day and a half is required to create a patient model. CT scans and the resulting three-dimensional models are presented.
