Cylindrical Transducer Array for Intravascular Shear Wave Elasticity Imaging: Preliminary Development
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control（2022）
摘要
We present an intravascular ultrasound (IVUS) transducer array designed to enable shear wave elasticity imaging (SWEI) of arteries for the detection and characterization of atherosclerotic soft plaques. Using a custom dicing fixture, we have fabricated single-element and axially-segmented array transducer prototypes from 4.6-Fr to 7.6-Fr piezoceramic tubes, respectively. Focused excitation of the ...
