Abstract
The lesions induced by dual-frequency high-intensity focused ultrasound (HIFU) in freshly excised porcine livers were investigated and compared with the lesions induced by conventional single-frequency HIFU. The results have shown that using different exposure time resulted in lesions of different sizes in both dual-frequency and single-frequency HIFU modes at the same intensity level (ISAL = 808 W cm−2), but the dimensions of lesions in dual-frequency mode were obviously larger than those in single-frequency mode. A much possible explanation was suggested for the results and the possibilities of applications in the future were also discussed in brief.
