Intravascular Ultrasound Imaging Apparatus, Interface, Architecture, and Method of Manufacturing

摘要

Sold-state intravascular ultrasound (IVUS) imaging devices, systems, and methods are provided. Some embodiments of the present disclosure are particularly directed to compact and efficient circuit architectures and electrical interfaces for an ultrasound transducer array used in a solid-state IVUS system. In one embodiment, an intravascular ultrasound (IVUS) device includes: a flexible elongate member; an ultrasound scanner assembly disposed at a distal portion of the flexible elongate member, the ultrasound scanner assembly including an ultrasound transducer array; an interface coupler disposed at a proximal portion of the flexible elongate member; and a cable disposed within and extending along a length of the flexible elongate member between the ultrasound scanner assembly and the interface coupler. The cable includes four conductors electrically coupling the ultrasound scanner assembly and the interface coupler.
