Ultraschallrückkopplung für Gewebeablationsverfahren

摘要

Bubble generation during a tissue ablation procedure is identified or detected. The ultrasound imaging is optimized to better detect generation of bubbles for more refined visualization and control of the ablation procedure. The generation of bubbles may alternatively or additionally be quantified to assist in control and/or diagnosis during an ablation procedure. Signals are generated based on the detection of a change in bubble characteristics. For example, the detection of type 2 or type 1 bubble generation is used to generate audio or visual warning signals. As another example, detection of type 1 or type 2 bubbles triggers generation of a control signal for increasing, decreasing or terminating the ablation energy. The generation of the control signal is performed automatically rather than relying on user visualization and reaction.
