Intraoperative transrectal diagnostic ultrasonography from HIFU device demonstrating the rectal tumour before treatment and hyperechoic changes after treatment in the sector targeted, confirming cavitation and tissue ablation. The Sonablate® 500 HIFU device is able to generate diagnostic ultrasonography and therapeutic HIFU simultaneously from the same transducer.
