1. A system for performing ablation, comprising:
an ablation device configured to ablate tissue in accordance with control parameters and configured to take measurements during ablation;
an imaging system configured to measure an elastographic related parameter indicative of ablation progress; and
a parameter estimation and monitoring module configured to receive feedback comprising the measurements from the ablation device and/or the elastographic related parameter from the imaging system, and configured to adaptively adjust imaging parameters of the imaging system at different times during ablation based on the feedback, wherein the feedback provides information that tissue stiffness has changed, wherein the imaging parameters include: pulse repetition frequency, number of track locations, and/or spacing between tracking beams, and wherein the adjusted imaging parameters change a sampling rate for measurements from the ablation device and/or the elastographic relates parameter.
