Sustained local hyperthermia in a murine mammary tumor for 12 min. Sustained, long-term sonication was achieved with minimal overshoot, a 0.49 °C standard deviation of the error, and 0.56 °C RMSE after the initial temperature rise. The PID controller responded to sudden changes in focal temperature as indicated by the red arrows. The 1.4 mm by 10 mm contour of the transducer focus is indicated by the white oval
