  • Abstract The distribution of the intensity field of ultrasound is complicated and not fully explored. Focused ultrasound surgery demands the understanding how all the variables influence the heating region near the ultrasound focal point. The high temperature generated from the treated area should be prevented from damaging the normal tissue which is one of the most significant studies of this subject.
      With the high-frequency ultrasound focusing transducer, this study combines the theories and the simulation to explore the intensity distribution and features due to the generated wave field. Furthermore, the functions of the spherical transducers are investigated. Through the bio-heat transfer equation, finally, the temperature distribution formed by the ultrasound wave field in the tissue is validated by the experiments. Then, this study can be used as the reference for the future design of the transducer and the therapy procedures.
