Figure 2.

Illustration of the treatment planning model process. Patient CT data are segmented and used to define the geometries for 3 D finite element models. Pressure fields are used to calculate heat generation terms which are subsequently applied to thermal finite element models. Their four-dimensional outputs (temperature history in three dimensions) are used to simulate volumetric hyperthermia by moving the thermal data according to a prescribed trajectory and rate. New features in the present study are shown at the bottom of the figure (italic text) and are aligned with the part of the model where they are introduced.
