Identifying cavitation regions using spectral and intensity data; application to HIFU

Abstract:

The high power intensities in HIFU often result in bubble production, either through cavitation or boiling, which are believed to be a primary contributor to tissue necrosis. Bubbles are associated with the bright hyperechoic regions in ultrasound B-mode images. As the only changes observed on tissue are subtle during treatment, some HIFU therapy protocols rely on the observation of significant brightness changes as the indicator of tissue lesions. The occurrence of a distinct hyperechoic ...
