    Abstract

    The analysis of temperature rise due to the absorption of ultrasound is important for the clarification of the effect of ultrasound waves and the estimation of medium constants. The thermal behavior of ultrasound is used not only for thermotherapy but also in measurement techniques. The estimation of a medium constant becomes possible by analyzing the temperature rise because the temperature change of the medium is particular to each medium. The purpose of this research is to establish a method of estimating medium constants and to develop a numerical simulation method that can be applied to the estimation of medium constants. We elucidated the requirements under which the simulation result corresponds to the experimental result. Good agreement between the experimental and simulation results is shown in this paper, and the validity of this method is described.
