Background A noninvasive technique to monitor thermal lesion formation is necessary to ensure the accuracy and safety of high-intensity focused ultrasound (HIFU) treatment. The purpose of this study is to ultrasonically detect the tissue change due to thermal coagulation in the HIFU treatment enhanced by cavitation microbubbles. Methods An ultrasound imaging probe transmitted plane waves at a center...
Shear wave elastography is expected as a noninvasive monitoring method in high-intensity focused ultrasound treatment. Since elastography is usually applied to detect a lesion near a superficial layer, it is challenging to induce and propagate shear waves in deep tissue. Acoustic cavitation bubbles have the potential to promote the efficiency of the treatment; however the presence of remaining microbubbles...
