ULTRASOUND GENERATING APPARATUS |
摘要 |
<p>Ultrasound energy originating from an emitter at a number of predetermined positions is sensed by a plurality of duplex transducers in a predefined arrangement. Each transducer produces a sensor signal representing ultrasound energy sensed by it, and the sensor signals of each transducer are stored in association with the predetermined position producing the sensor signal. Thereafter, an ablation pattern corresponding to a group of the predetermined positions may be generated by actuating each transducer with a time-reversed version of the sensor signals stored in association with the group of positions. By placing the transducers in a predetermined spatial relationship to the heart, the ablation pattern may be formed on the ostium of a pulmonary artery. Preferably the predetermined positions correspond to a grid of dots that may be used to approximate virtually any shape.</p> |
