(a) Illustration of the two simulation models. Model 1: optimizing the size and the temperature range of the heating tunnel. Model 2: simulating the heating tunnel produced by HIFU within the intralipid phantom. (b) Temperature and scattering-coefficient distributions of the four-layer heating tunnel used in model 2.
