Post ultrasound-exposure cooling profiles. Post ultrasound-exposure cooling profiles. Temperatures are along the direction of ultrasound propagation through the center of the ultrasound focus at times 0, 10, 30 and 60 seconds after termination of exposure. The 1.5-MHz transducer models are shown in (a) and (b). The 3.2-MHz transducer models are shown in (c) and (d). After 30 seconds, temperatures cool to within 1°C of 37°C (body temperature).
