Dicing is typically required to create elements for array transducers made with piezoelectric
ceramics. Kerfs, which are the cutting spaces generated during dicing, are introduced to …

A 20 MHz high density linear array transducer is presented in this paper, This array has
been developed using an optimized ceramic-polymer composite material. The electro …

Transducers with larger aperture size are desirable in ultrasound imaging to improve
resolution and image quality. However, in practice inhomogeneities and aberrating layers …

Piezocomposites that can operate at frequencies above 30 MHz without spurious modes are
required in order to develop sufficiently sensitive high frequency arrays for high resolution …

Array ultrasonic transducers using electronic scanning method can obtain high frame rate
and high-accuracy images compared with single-element transducers. However, for array …

Abstract For high frequency (> 20 MHz) ultrasound transducer arrays, structures in the range
of a few micrometers are required. Especially, separating transducer elements of a few …

Transducers with a larger aperture size are desirable in ultrasound imaging to improve
resolution and image quality. A coherent multi-transducer ultrasound imaging system …

Multi-Line Transmission (MLT) is a potential approach to increase the framerate in 3D
echocardiography, but suffers from artifacts caused by the cross-talk between the …

Novel ultrasound arrays used in medical imaging contain many small elements (down to
100 μm) operating at high frequencies (upto tens of MHz). In such arrays, each element …

A ceramic injection molding process has been developed for net-shape forming complex-
shaped PZT 1-3 and 2-2 element arrays that are suitable for direct assembly into composite …
