Abstract:
1. An imaging system for use with an ultrasound system, the imaging system comprising: a high intensity focused ultrasound (HIFU) transducer having a plurality of transducer elements for treatment of a volume of living tissue; a video display having an X-Y coordinate display, the display having a plurality of pixels wherein each pixel has an X-Y address; and a controller configured to power said HIFU transducer, said controller having a video output configured to produce the X-Y coordinate display on the video display and a receive path configured to detect acoustic information from said volume of living tissue, the receive path comprising: a first receive channel configured to detect boiling by analyzing broad spectrum acoustic interaction radiating from said volume of living tissue; and a second receive channel separate from the first receive channel configured to detect cavitation by analyzing sub-harmonic frequencies (f/n) radiating from said volume of living tissue; wherein the video output is further configured to simultaneously provide a visual representation of boiling and a visual representation of cavitation if present at any particular pixel on the video display based upon detecting boiling and cavitation via the first and second receive channels.
