Texte intégralDyanmic elastography is an imaging method to measure the elasticity of biological tissues in a non-invasive and quantitative way. Recently, the transposition of the technique to a small scale has been called dynamic micro-elastography and has allowed the first measurements of cellular elasticity by shear waves using an optical microscope. This thesis aims to undetstand the limits of this technique and to develop new micro-elastography methods, to test new wave sources but also potential applications of the technique. In a first step, the dispersion of shear waves was studied on gelatin phantoms. Two distinct regimes of guided elastic waves and shear waves were identified. The high-frequency limit of wave propagation was also explored, establishing the existence of a cutoff frequency which explains the absence of ultrasonic shear imaging. The same approach was then applied to visco-elastic fluids, revealing two cutoff frequencies and revisiting previous studies on rheology and wave propagation in this type of medium. Then, the initial objective being to carry out micro-elastography on single cells and the experiments previously carried out with micro-pipettes presenting certain defects, an original method of cellular micro-elastography was developed. An oscillating microbubble is used as a contactless shear wave source at 15 kHz to perform experiments on blood cells whose diameter is about 15 µm. These are the smallest objects ever explored by elastography. Larger objects, cell clusters of a few tens of thousands of cells have also been studied. Indeed, since ultrasound elastography of these tumour models of about 800 µm in diameter is impossible, optical micro-elastography is a suitable technique. These samples contain magnetic nanoparticles, so a magnetic pulse could be used as a wave source. Previously, proofs of concept on both macroscopic (in ultrasonic elastography) and microscopic (in optical micro-elastography) phantoms were conducted to validate the use of this diffuse field source. Finally, pulse wave measurements were performed on retinal arteries of about 50 µm in diameter using laser Doppler holography acquisitions performed in vivo. The application of monochromatic correlation algorithms allowed the measurement of guided wave velocities, finally revealing the existence of a second pulse wave, an antisymmetric bending wave. This guided wave, much slower than the axisymmetric pulse wave studied so far, was also observed on the carotid artery thanks to ultrafast ultrasound acquisitions

Texte intégralTumor development is complex process made possible thanks to the microenvironment surrounding tumor cell. Modifications induced by tumor cells on their environment enable their own development by remodeling tissues sustaining them and by creating a new vascular network (angiogenesis). The use of several antiangiogenic therapies, inhibiting the sprout of a new vascular network, has been authorized in clinic. These therapies induce strong modifications in tumors at the functional level and following tumor size changes are is not sufficient to fully characterize tumor modifications. The main goal of this thesis was to use different ultrasound-based imaging modalities in order to assess their sensitivity to modifications induced in murine tumor model (colorectal and lung carcinomas) during different type of therapy (chemical: cytotoxic, antiangiogenic / physical: cold plasma, sonosensitization). Modifications of the spatial distribution of microvessels and their functionality were characterized using contrast-enhanced ultrasound (CEUS), alteration of tumor microstructure was assessed using spectral analysis of radiofrequency signal, known as quantitative ultrasound (QUS) and finally variations of mechanical properties in tumor tissues were measured in shear wave elastography (SWE). In order to better understand the origin of the modifications observed in vivo, standard parameters such as level of fibrosis and necrosis were characterize ex vivo in tumor tissue using immunochemistry as gold standard
