Abstract: A storage unit holds representations of sensor signals which would be received by a set (30) of ultrasonic transducers (32) from an ultrasonic impulse emitter positioned at each of plural points (P) in the frame of reference of the transducer set. An impulse may be applied at a particular point by using the representation associated with that point to generate an actuation signal corresponding to a time-reversed version of the sensor signal. Impulses may be applied in a pattern (150) by using those representations associated with points in the pattern to generate actuation signals and applying those signals to the transducer set. By placing the transducer set in a known spatial relationship to the a body structure such as heart, an ablation pattern may be formed in a desired relationship to the body structure, such as around the ostium of a pulmonary vein.
