    • An ultrasound catheter probe assembly capable of scanning a three-dimensional volume is provided. The ultrasound catheter probe assembly contains a plurality of ultrasonic transducers disposed along a central axis of the ultrasound catheter probe assembly. The plurality of ultrasonic transducers is disposed on a mechanism operable to reciprocally pivot the plurality of ultrasonic transducers enabling the plurality of ultrasonic transducers to scan a three-dimensional volume. A helically disposed electrical interconnection member may be disposed about a pivot axis of the plurality of ultrasonic transducers and may electrically interconnect the plurality of ultrasonic transducers to an ultrasound imaging system. The ultrasound transducer catheter probe assembly may be fluid-filled and contain bubble position control and fluid expansion compensation features.
    • 提供能够扫描三维体积的超声波导管探针组件。 超声导管探针组件包含沿着超声波导管探头组件的中心轴布置的多个超声换能器。 多个超声波换能器设置在可操作以使多个超声波换能器往复枢转的机构,使得多个超声换能器能够扫描三维体积。 螺旋设置的电互连构件可以围绕多个超声换能器的枢转轴设置,并且可以将多个超声换能器电连接到超声成像系统。 超声波换能器导管探针组件可以是流体填充的并且包含气泡位置控制和流体膨胀补偿特征。
