The high acoustic intensity in HIFU often results in bubble production, either through acoustic cavitation or boiling. Both these are believed to be a primary contributor to tissue necrosis. Some HIFU protocols rely on the evidence of cavitation as a strong indicator of tissue lesions. Cavitation is normally associated with hyperechoic regions (dasiabright uppsila) in ultrasound B-mode image feedback...
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 appearance of bright hyperechoic regions in ultrasound B-mode images are observed from the bubbles. As they are often the only changes observed during treatment on tissue, some HIFU protocols rely...
