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 …

The sparse array technique is an excellent approach to tackle the connection difficulties due
to the huge number of elements of 2D matrix arrays. However, the reduction of the element …

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 …

Matrix sparse array optimization for 3D ultrasound imaging often uses simulated annealing
(SA) algorithms to reduce the number of elements and to find their best position, intensity …

3D Ultrasound imaging is a fast-growing medical imaging modality. In addition to its
numerous advantages (low cost, non-ionizing beam, portability) it allows to represent the …

The non-grid sparse array technique is a promising approach to overcome the connection
difficulties of 2D matrix arrays and to partially compensate the energy loss linked to the …

In this work we have investigated the effect of curving phase-steered sparse periodic two-
dimensional arrays in one direction, and relate this effect to the geometry of the arrays. We …

In this paper, an optimization method aimed at designing aperiodic linear sparse arrays is
proposed that is based on the stochastic optimization methodology called simulated …

This work presents the outputs from a project which aimed to lay the foundation of a 3D
ultrasound imaging system where the emphasis was on real-time data acquisition and near …

2D matrix probes present a real capability for three dimensional ultrasound imaging. The
main difficulties to implement these probes come from the need of using a huge number of …
