    Quantitative and functional ultrafast ultrasound imaging of the human brain

    At : IPGP, Amphithéâtre, 1 rue Jussieu, 75005 Paris , on 14:00

    The objective of this thesis was to explore the potential of human brain ultrasound imaging. Anatomy, blood flow and soft tissue stiffness have already been studied with ultrafast ultrasound imaging in humans and validated in several organs, such as, the breast and liver but not yet on the adult brain. The main limitation of transcranial ultrasound imaging is today the very strong skull-induced aberration artefact. Indeed, the bone, due to its composition, does not allow for ultrasound propagation as elsewhere in the human body. Therefore, this thesis was focused on the development of ultrafast ultrasound imaging for the evaluation of soft tissue stiffness and neurofunctional imaging in the adult human brain, during brain surgery to bypass the problem of skull aberration, and on an aberration correction technique for transcranial ultrasound imaging. We first provided several evidence of the benefit of using shear wave elastography during brain surgery. We also presented our new technique for 3D shear wave elastography using a matrix array in order to be able to overcome the limitations of 2D imaging and in particular to reduce the operator dependence. In a second phase, we demonstrated the capability of ultrasound to identify, map and differentiate in depth cortical regions of activation in response to a stimulus, both in awake patients and in anaesthetized patients. We have demonstrated that ultrasound neurofunctional imaging has the potential to become a comprehensive modality of neuroimaging with major benefits for intraoperative use. In a third part, we developed a new sound speed estimation (SSE) technique, based on a three-step technique that estimates the sound speed accurately corresponding to the illuminated medium. This technique was tested in ultrasound phantoms and in vivo in patient’s liver. In both cases, our method was able to find the sound speed corresponding to the medium. We demonstrated that SSE was related to the fat fraction. This analysis led to the conclusion that SSE was able to distinguish a healthy liver from a diseased liver with both biopsy and MRI as gold standard. Combined with the use of the Wood’s formula, we were even able to access a fat fraction measured by non-invasive ultrasound. Finally, by combining the phase, the amplitude and the sound speed estimation, we have developed a new aberration correction algorithm to perform transcranial ultrasound imaging. By performing numerical simulations, we obtained images that faithfully represented the medium (lateral position and depth) and characterized by one resolution and one contrast similar to those obtained with a punctual source in the medium.

    Quasithermalization de fermions dans un Potentiel Quadrupolaire et refroidissement évaporatif d'un gaz de 40K jusqu'à la dégénérescence Quantique

    At : Salle Conf. IV - E244 24 rue Lhomond 75005 Paris , on 14:00

    In this thesis we investigate experimentally the physics of a cold fermionic mixture consisting of 6Li and 40K. After a short description of the experimental apparatus and of a few technical particularities implemented during my PhD, for example the light-induced atomic desorption in the 2D-MOT by UV-light, we focus on two main observations of the fermionic nature of the gas. The first part describes the quasithermalization of 6Li in a magnetic quadrupole potential. Even though collisions are absent in a spin-polarized fermionic gas below a given temperature, the statistical ensemble undergoes energy redistribution after an excitation within the linear potential. We present an extensive experimental study as well as a comprehensive theoretical analysis. Moreover, the studied Hamiltonian can be canonically mapped onto a system of massless, harmonically trapped particles and the previously developed results are re-interpreted in order to describe this experimentally inaccessible system. A further development of the realized experiment allows even for the implementation of spin-orbit coupling in a gas of non-interacting fermions. In the second part, we describe the evaporative cooling of 40K to quantum degeneracy. Through different evaporative cooling stages we reach with a final number of 1.5e5 atoms in the ground-state a temperature of 62nK, which corresponds to 17% of the Fermi temperature.

    Effets de grande échelle en Turbulence

    At : Conf IV - ENS - 24 rue Lhomond 75005 Paris , on 14:00

    This manuscript describes how solutions of the Navier-Stokes equations behave in the large scales when forced in the small scales. It analyzes also the large scale behavior of magnetic fields solution of the kinetic induction equation when the velocity is in the small scales. The results were acquired with direct numeric simulation (DNS) using pseudo-spectral algorithms of the equations as well as their Floquet development. In the hydrodynamical case, the Floquet DNS were able to confirm the results of the AKA effect at low Reynolds number and extend them for Reynolds number of order one. The DNS were also used to study AKA-stable flows and identified a new instability that can be interpreted as a negative viscosity effect. In the magnetic case, the alpha effect is observe for a range of scale separation exceed know results by several orders of magnitude. It is also shown that the growth rate of the instability becomes independent of the scale separation once the magnetic field is destabilized in its small scales. The energy spectrum and the correlation time of absolute equilibrium solution of the truncated Euler equation are presented. A new regime where the correlation time is governed by helicity is exhibited. These results are also compared with those coming from large scale modes of solutions of the Navier-Stokes equation forced in the small scales. They show that the correlation time increases with the helicity of the flow.

    Nonlinear and quantum effects in analogue gravity

    At : Amphi LPT Orsay , on 14:00

    This thesis deals with some properties of classical and quantum scalar fields in an inhomogeneous and/or time-dependent background, focusing on models where the latter can be described as a curved space-time with an event horizon. While naturally formulated in a gravitational context, such models extend to many physical systems with an effective Lorentz invariance at low energy. We shall see how this effective symmetry allows one to relate the behavior of perturbations in these systems to black-hole physics, what are its limitations, and in which sense results thus obtained are “analogous” to their general relativistic counterparts. My collaborators and I focused on three aspects of the behavior of fields close to the (analogue) event horizon in models with an effective low-energy Lorentz symmetry. The first one concerns nonlinear effects, which had been given little attention in view of their crucial importance for understanding the evolution in time of Hawking radiation as well as for experimental realizations. We showed in particular how they determine the late-time behavior in stable and unstable configurations. The second aspect concerns linear and quantum effects. We studied the Hawking radiation itself in several models and what replaces it when continuously erasing the horizon. We also characterized and classified the different types of linear instabilities which can occur. Finally, we contributed to the design and analysis of “analogue gravity” experiments in Bose-Einstein condensates, hydrodynamic flows, and acoustic setups, of which I report the main results.
