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).

Abstract: The present disclosure is directed towards systems and methods for detecting and sizing mineralized tissue. An exemplary method, according to an embodiment of the present disclosure, can provide for imaging a region of interest containing the mineralized tissue with unfocused ultrasound beams via a primary imaging method. The method can then provide for computing a wavefront coherence at the imaged region of interest. The method can then provide for segmenting pixels of the imaged region of interest based on their intensities and intensities of surrounding pixels. The method can then provide for identifying a border and a shadow of the mineralized tissue based on the segmenting. Then, the method can provide for calculating a size of the mineralized tissue based on the border and the shadow.

Abstract: Methods, computing devices, and a computer-readable medium are described herein related to fragmenting or comminuting an object in a subject using a burst wave lithotripsy (BWL) waveform. A computing device, such a computing device coupled to a transducer, may carry out functions for producing a BWL waveform. The computing device may determine a burst frequency for a number of bursts in the BWL waveform, where the number of bursts includes a number of cycles. Further, the computing device may determine a cycle frequency for the number of cycles. Yet further, the computing device may determine a pressure amplitude for the BWL waveform, where the pressure amplitude is less than or equal to 8 MPa. In addition, the computing device may determine a time period for producing the BWL waveform.
