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 …

Two-dimensional (2-D) arrays offer volumetric imaging capabilities without the need for
probe translation or rotation. A sparse array with elements seeded in a tapering spiral …

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 …

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 …

Spiral array transducers with a sparse 2-D aperture have demonstrated their potential in
realizing 3-D ultrasound imaging with reduced data rates. Nevertheless, their feasibility in …

To be able to describe more precisely the behavior of a real-time 3-D ultrasound system with
either a dense array or various sparse designs, experimental data from a 2-D fully …

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 …

Open scanners enable 3-D experimental imaging research but have been so far limited to
the use of 2-D sparse or row-column arrays having a relatively low number of elements …

Coherent multi-transducer ultrasound (CoMTUS) creates an extended effective aperture
through the coherent combination of multiple arrays. In this study, for the first time, CoMTUS …

Recent studies suggest that ultrasound can be used for serial monitoring to guide
therapeutic interventions at the point of care. A low-cost 3-D imaging may be well suited for …
