Journal ArticleDOI
Supersonic shear imaging: a new technique for soft tissue elasticity mapping
TL;DR: The first in vivo investigations made on healthy volunteers emphasize the potential clinical applicability of SSI for breast cancer detection and results validating SSI in heterogeneous phantoms are presented.
Journal ArticleDOI
Smart radio environments empowered by reconfigurable AI meta-surfaces: an idea whose time has come
Marco Di Renzo,Merouane Debbah,Dinh-Thuy Phan-Huy,Alessio Zappone,Mohamed-Slim Alouini,Chau Yuen,Vincenzo Sciancalepore,George C. Alexandropoulos,Jakob Hoydis,Haris Gacanin,Julien de Rosny,Ahcène Bounceur,Geoffroy Lerosey,Mathias Fink +13 more
TL;DR: This paper overviews the current research efforts on smart radio environments, the enabling technologies to realize them in practice, the need of new communication-theoretic models for their analysis and design, and the long-term and open research issues to be solved towards their massive deployment.
Journal ArticleDOI
Measuring the transmission matrix in optics: an approach to the study and control of light propagation in disordered media.
Sebastien M. Popoff,Geoffroy Lerosey,Rémi Carminati,Mathias Fink,A. C. Boccara,Sylvain Gigan +5 more
TL;DR: The transmission matrix of a thick random scattering sample is determined and it is shown that this matrix exhibits statistical properties in good agreement with random matrix theory and allows light focusing and imaging through the random medium.
Journal ArticleDOI
Coherent plane-wave compounding for very high frame rate ultrasonography and transient elastography
TL;DR: It is proposed to improve the beamforming process by using a coherent recombination of compounded plane-wave transmissions to recover high-quality echographic images without degrading the high frame rate capabilities.
Journal ArticleDOI
Time reversal of ultrasonic fields. I. Basic principles
TL;DR: Pulsed wave time-reversal focusing is shown using reciprocity valid in inhomogeneous medium to be optimal in the sense that it realizes the spatial-temporal matched filter to the inhomogeneity propagation transfer function between the array and the target.
