To advance the qDSA algorithm beyond mean velocity estimations by quantifying systolic and diastolic waveform parameters using 2D image-derived features.

To develop a model of pressure distribution exerted by the histotripsy coupling water bath (with flexible membrane) to predict abdominal organ deformation for advanced histotripsy treatment planning.
