Key requirements to boost the applicability of Ultrasonic systems for in-situ, real-time
operations are low hardware complexity and low power consumption. These features are …

Conventional ultrasound imaging relies on the computation of geometric time delay from
multiple sensors to detect the position of a scatterer. In this paper, we present Ergodic Relay …

A problem that arises when the time-reversal process is applied in a nonlinear regime is
related to the generation of harmonics: conventional piezoelectric transducers cannot work …

In this work, the propagation of an ultrasonic nonlinear wave through a multiple scattering
medium is experimentally studied. The interaction between multiple scattering and nonlinear …

Ultrasound shock wave therapy is increasingly used for non-invasive surgery. It requires the
focusing of very high pressure amplitude in precisely controlled focal spots. In transcostal …

Time Reversal cavities (TRC) have been investigated in medical ultrasounds in the past, for
either shockwave therapy or imaging. They indeed allow small foci formation in large …

Time reversal cavities (TRC) have been proposed as an efficient approach for 3D ultrasound
therapy. They allow the precise spatio-temporal focusing of high-power ultrasound pulses …

The blood spinal cord barrier (BSCB) and blood brain barrier (BBB) are semi-permeable
barriers separating the spinal cord and brain vasculature from the parenchyma. Focused …
