    Advantages and Disadvantages of HIFU ceramics transducer

    Compared with surgery, HIFU ceramic transducer for machine is non-invasive and has few complications. Compared with radiotherapy, H IFU can obtain a therapeutic dose in one irradiation, and can also repeat the treatment of residual lesions or locally recurring lesions. The use of H IFU does not excl
