During the haemodialysis session, the blood is purified through an extracorporeal artificial kidney. High flow in the surgically created vascular access, arterio-venous fistula AVF, leads to a successful blood suction and reinjection. In order to understand the relation between the blood flow dynamics and the physiopathology, it is necessary to understand its characteristics in these vessels. Clinically it is possible to measure blond vectors using the colour echo Doppler. Nevertheless this method is has its limitations. Therefore we propose to use biomechanical model. In this work we have studied blood flow dynamics in patient specific AVF. The principal object was to define and validate a robust methodology capable of simulating blood flow in the AVF reconstructed from clinical examinations
Risser, Laurent. "Analyse quantitative de réseaux micro-vasculaires intra-corticaux". Toulouse 3, 2007. http://www.theses.fr/2007TOU30011.
This work is a quantitative investigation of intra-cortical micro-vascular networks using a new micro-tomography imaging protocol which permits a complete scan of the entire gray matter with a micron resolution. The first part of the PhD is devoted to the analysis of very large 3D images coming from healthy rats and marmosets primate cortex, as well as tumour implanted rats brains. Classical methods are used for binarisation and squeletonization of the images. The influence of the experimental protocol on the obtained images is evaluated. A fast and original method is proposed to fill the gaps of incompletely injected vessels the efficiency of which is tested and validated. The second part of the PhD is concerned by the statistical analysis of geometrical, local and topological properties of micro-vascular networks. Geometrical properties are related to the spatial distribution of vessels from studying the vascular density and the vessel/tissue distance map. We brought to the fore the multi-scale properties of those fields from fractal and spectral analysis up to a some cut-off which defines the typical length-scale of an elementary representative volume. We found that this length-scale significantly differ in normal and tumoral tissues. The local analysis of vessel's segment length systematically exhibits exponential distribution, which leads to some characteristic segments length. Those length significantly differ in adult and new-born primates tissues. This analysis is consistent with the result obtained on the vascular density and leads to the conclusion that developmental angiogenesis occurs mainly at the capillary scale. .

The main topic of this manuscript is surface statistic analysis. We define a new formalism that extends to a random framework the surface representation introduced by Glaunès and Vaillant (2005). This formalism is based on a notion of random linear form, which is inspired from the theory of generalized random process, developped by Itô (1954) and Gelfand and Vilenkin (1964). On this representation, we set a probabilistic model that describes the variability of surfaces ; by a transition from continuous to discrete, we extend it to an observation model that describes experimental data. We build estimators for the mean representant of a surface sample and for the autocovariance of the noise. We demonstrate that these estimators are consistent. We report some experiments in which we test our estimation method on simulated data. We apply our statistical framework to classification of brain surfaces from MRI, using a Bayesian classification procedure
