Elimination of HIFU Components in Monitoring of High-Intensity Focused Ultrasound Lesion Formation

Abstract (in Japanese) (See Japanese page) 
(in English) Ultrasonic detection of focal tissue coagulation thermally induced by high-intensity focused ultrasound (HIFU) has been difficult without the involvement of microbubbles. A significant length of interval between HIFU shots is set for monitoring target tissue to avoid interference between HIFU noise and RF echo signals in conventional ultrasound monitoring of HIFU treatment. This way, it is difficult to detect tissue changes in the order of milliseconds, which is required for dynamically controlling the HIFU exposure. In this study, a new filtering method to handle RF signals before beam forming is proposed, which will enable truly real-time detection of tissue coagulation during HIFU exposure.
