As one of the most important and well established tools, ultrasound imaging provides noninvasive valuable diagnostic information, especially in the form of cross-sectional images of soft tissues. In this work, we report the design, fabrication, and characterization of press-focused LiNbO3 transducer with one matching layer only. The performance of these transducers is in good agreement with the simulation...
As one of the most important and well established tools, ultrasound imaging provides noninvasive valuable diagnostic information, especially in the form of cross-sectional images of soft tissues. High frequencies are used directly to enable high resolution imaging to be of clinical benefit. As a result, high-frequency ultrasonic transducers with better resolution are needed. The difficulty of a high...
