Schematic illustration (top view and side view) of the experimental setup. The imaging array and therapeutic transducer were fixed at a 37° angle so the acoustic axis of the therapy transducer was parallel with a specific image line of the sector array. This image line was identified in a water tank using a line target and marked on the screen of the ultrasound scanner. This image line was then used to warrant the acoustic access to the left ventricular wall. Subsequently, the transducer/probe gantry was translated so the therapy transducer beam followed the same path as for the previously identified image line
