Figure 9.

Simulated and experimental temperature profiles in phantoms with an applicator placed 10 mm (A) and 25 mm (B) from a rib surface. Temperature along a line perpendicular to the bone surface and adjacent to the center of one transducer, as in Figure 3B, is plotted as a function of distance from the bone surface, which is at x = 0. Recordings were made after 10 minutes of heating. The experimental curve is an average of the recordings in 3-4 experiments with the applicator at the given position. The bone surface is at x = 0. Positive x-values indicate locations in the phantom, and negative values are inside the bone.
