Computer simulation is being used to plan patient treatments for deep regional hyperthermia in the Sigma 60 applicator of the BSD-2000 Hyperthermia System. The method used is the finite-difference time-domain (FDTD) method. As with all simulation methods, confirmation of the accuracy via measured data is important. Previously, most such measurements in the Sigma 60 were done with homogeneous phantoms. A new phantom using both muscle and fat equivalent material has been constructed, presenting a more challenging simulation problem to the FDTD method. The description of the phantom and the results of comparisons between simulated and measured data are presented
