Abstract Structure design of medical ultrasonic transducers is of prime importance, as it not
only affects the transducer's imaging performance, but also limits its application scene and …

Over the past decades, real-time three-dimensional (3D) medical ultrasound has attracted
much attention since it enables clinicians to diagnose more accurately. This calls for …

In this work the sound speed of components in a one-dimensional array transducer used to
acquire ultrasonic cross-sectional images for medical diagnosis was studied. The transducer …

High frame rate three-dimensional (3D) ultrasound imaging would offer excellent
possibilities for the accurate assessment of carotid artery diseases. This calls for a matrix …

Accurate diagnostics of stenosis and blood flow distribution in carotid arteries requires
transducers capable of producing 3D volume images with high frame rate for real time …

To accurately investigate the state of the carotid artery by the local haemodynamics and
motion of the plaque using ultrasound, high-frame rate volumetric imaging is necessary. We …

This thesis describes the design, fabrication, and characterization of a Lead-Zirconate-
Titanate (PZT) matrix transducer integrated on an Application Specific Integrated Circuit …

A dual frequency probe using a multi-layer piezoelectric material is proposed for
simultaneous ultrasound and photoacoustic imaging of the carotid artery with a high …
