Abstract
Apparatus and methods are described including positioning an ultrasound transducer at a blood vessel ostium, rotating the transducer about its axis and scanning tissue of the blood vessel ostium, recording one or more baseline returned signals from the tissue, and creating a baseline image of the blood vessel ostium based on at least one of the returned signals. Tissue of the blood vessel ostium is ablated in consecutive segments by rotating the transducer segmentally until full rotation is completed. The returned signals of the ablated segments are recorded in real-time and a real-time image is created based on the one or more returned signals. Ablation is terminated after changes in the real-time returned signals and/or real-time image with respect to the baseline returned signals and/or baseline image indicate an achieved predetermined level of ablation lesion formation. Other applications are also described.
