Experimental Verification of Modeled Thermal Distribution Produced by a Piston Source in Physiotherapy Ultrasound

Figure 8

Contour plots for the experiment (left side of each distribution) and models (right side of each distribution) at two different heating times: (a) and (c) 150 s; (b) and (d) 300 s. (a) and (b) Experiment is compared with temperature produced by the piston (model A). (c) and (d) Experiment is compared with the results when modeling the heat produced by the measured acoustic field (model B). Contours from border to center: .
