Radiation force on absorbing targets and power measurements of a high intensity focused ultrasound (HIFU) source

Abstract: Based on the analytic expressions for the radiated field of a circular concave piston given by Hasegawa et al., an integral for calculation of the radiation force on a plane absorbing target in a spherically focused field is derived. A general relation between acoustic power P and normal radiation force F n is obtained under the condition of kr 1. Numerical computation is carried out by using the symbolic computation program for practically focused sources and absorbing circular targets. The results show that,… Show more

“…After then, based on the ray acoustic model, Shou et al (1998;2006) obtained the same result on a totally absorbing target in the focused acoustic field. Over the last 30 years, the radiation force balance (RFB) means has successfully been verified in some international comparisons (Beissner et al, 1996;Civale et al, 2018), and the related details have repeatedly been described in literatures (Beissner, 2010;Qian et al, 2010;Xu et al, 2019).…”
