The effects of ultrasound exposure on the living body can be divided into thermal and non-thermal effects. In this study, the thermal effect was considered and temperature elevation due to ultrasound exposure was examined. First, experimental apparatus for measurement of temperature elevation was considered. Then, fundamental experiments to record the thermal effect of ultrasound waves on different substances were carried out. These included measuring the acoustic characteristics and temperature elevation of degassed water, tissue samples and samples made from agar, having properties similar to those of tissues. It was clarified on noted that the attenuation constant of tissue decreases after ultrasound exposure. Finally, it proposed that the viscosity of a target changes according to ultrasound exposure, and the proposition was investigated experimentally.
