FOCUSED ROTATIONAL IVUS TRANSDUCER USING SINGLE CRYSTAL COMPOSITE MATERIAL |
摘要 |
An ultrasound transducer for use in intra-vascular ultrasound (IVUS) imaging systems including a single crystal composite (SCC) layer is provided. The transducer has a front electrode on a side of the SCC layer; and a back electrode on the opposite side of the SCC layer. The SCC layer may have a dish shape including pillars made of a single crystal piezo-electric material embedded in a polymer matrix. Also provided is an ultrasound transducer as above, with the back electrode split into two electrodes electrically decoupled from one another. A method of forming an ultrasound transducer as above is also provided. An IVUS imaging system is provided, including an ultrasound transducer rotationally disposed within an elongate member; an actuator; and a control system controlling activation of the ultrasound transducer to facilitate imaging. |

1. An ultrasound transducer for use in intra-vascular ultrasound (IVUS) imaging systems, the transducer comprising:
a single crystal composite (SCC) layer; a front electrode on a side of the SCC layer; and a back electrode on the opposite side of the SCC layer; wherein:
the SCC layer includes pillars made of a single crystal piezo-electric material;the pillars are embedded in a polymer matrix; andthe SCC layer has a concave upper surface and an opposing convex lower surface. |
