Sparse 2D matrix arrays represent an alternative to fully populated arrays for a more efficient
use of available electronic channels. While individually driving the elements of fully …

3D ultrasound imaging is costly and complicated mostly due to the need of controlling 2D
probes with high numbers of elements (≥ 1024). Sparse arrays are a convenient way to …

Volumetric medical ultrasound imaging currently provides either high resolution or high
frame rates. We propose a sparse array probe with only 256 elements that are density …

The role of 2D matrix arrays in the realization of real time 3D ultrasound imaging is crucial as
the latter permit to acquire a complete volume. The lack of control systems for these arrays …

There is an increasing interest for sparse 2D arrays as an alternative to full gridded arrays
used in commercial systems. This work presents an effective and straightforward solution to …

A fully-sampled two-dimensional (2D) matrix array ultrasonic transducer is essential for fast
and accurate three-dimensional (3D) volumetric ultrasound imaging. However, these arrays …

Two-dimensional arrays enable volumetric ultrasound imaging but have been limited to
small aperture size and hence low resolution due to the high cost and complexity of …

Bio-medical ultrasound imaging has recently gained considerable attention. A two-
dimensional (2-D) array is essential for three-dimensional (3-D) volumetric imaging. Fully …

In real-time ultrasonic 3-D imaging, in addition to difficulties in fabricating and
interconnecting 2-D transducer arrays with hundreds of elements, there are also challenges …

Coherent multi-transducer ultrasound (CoMTUS) creates an extended effective aperture
through coherent combination of multiple arrays that results in significantly improved …
