1. A system for controllably delivering ablation energy to tissue, comprising:
- an energy transmitter operable to transmit ablation energy into body tissue;
an ultrasound detector configured to detect energy emitted by collapsing or shrinking bubbles resonating in body tissue receiving ablation energy transmitted by the energy transmitter; and
a control element operatively coupled to the energy transmitter and ultrasound detector, the control element configured to adjust an amount of ablation energy being transmitted by the energy transmitter in response to the energy detected by the ultrasound detector.

Abstract
A system for controllably delivering ablation energy to tissue includes an ablation device operable to supply ablation energy to body tissue causing bubbles to form in the tissue, an ultrasound transducer configured to detect energy spontaneously emitted by collapsing or shrinking bubbles that are resonating in the tissue, and a control element operably coupled to the ablation device and the ultrasound transducer element, the control element being configured to adjust the ablation energy supplied to the tissue in response to the energy detected by the ultrasound transducer to prevent tissue popping caused by bubble expansion.
