| Abstract: | In this paper the calculation method about radiation force has been studied. The formulas of radiation force acting on targets in the focused ultrasonic field are derived using ray acoustic method. The radiation forces on the totally reflecting target and on the totally absorbing target are discussed. Finally a measured result of acoustic power of a high intensity focused ultrasonic equipment by radiation force method is given. This result is very close to that measured by the calorimetry and the deviation between them is less than 3% |
