Experimental setup involving an ox liver tissue sample placed at the focus of a HIFU transducer driven at 3.3MHz. The HIFU transducer is co-aligned with a 4-11MHz array for B-mode imaging and passive recording of acoustic emissions. These emissions are filtered, isolating the 2nd and 3rd harmonic of the HIFU transmitting frequency, which are then processed using PAM
