摘要：
The steady state temperature field in human body generated by concave spherical surface focused ultrasound transducer for hyperthermia has been studied through solving bioheat conduction equation by the difference method in this paper. The influence of parameters of the transducer and biological tissue properties on the effective treated area has been analyzed through introducing the heat focal distance and isotherms, and characteristics of the sound field and temperature field are studied thoroughly.
