Ultrasound Imaging Catheters with Reciprocating Phased Array Transducers |
| 摘要 |
In one embodiment, a catheter imaging device includes an elongated catheter shaft having a forward looking ultrasonic transducer disposed at a distal end thereof. A first device is coupled to the transducer for sweeping an ultrasonic beam produced by the transducer in a first plane and through a first angle therein, and a second device is coupled to the transducer for sweeping the ultrasonic beam in a second plane and through a second angle therein, the second plane being disposed orthogonal to the first plane. In one aspect, the ultrasonic transducer includes a plurality of transducer elements. |
