Abstract
A method for attempting to fragment or comminute an object in a body using ultrasound includes producing a burst wave lithotripsy (BWL) waveform by a therapy transducer. The BWL waveform is configured to fragment or comminute the object. The BWL waveform includes a first burst of continuous ultrasound cycles and a second burst of continuous ultrasound cycles. A burst frequency corresponds to a frequency of repeating the bursts of the BWL waveform. The method also includes determining a cycle frequency f of the continuous ultrasound cycles within the first burst and the second burst based on a target fragment size D, where the cycle frequency is: f(MHz)=0.47/D(mm).
