Book Description
L'IMAGERIE D'IMPEDANCE EST UNE NOUVELLE METHODE D'IMAGERIE, QUI A POUR BUT DE RECONSTRUIRE LA DISTRIBUTION DE CONDUCTIVITE ELECTRIQUE AU SEIN D'UN MILIEU, A PARTIR D'INFORMATIONS ELECTRIQUES PROVOQUEES A SA PERIPHERIE. ELLE APPARAIT COMME POTENTIELLEMENT COMPLEMENTAIRE DES AUTRES TECHNIQUES UTILISEES EN IMAGERIE MEDICALE. CE TRAVAIL A POUR BUT L'ETUDE ET LE DEVELOPPEMENT D'ALGORITHMES DE RECONSTRUCTION. LA STRATEGIE ADOPTEE A CONSISTE A METTRE EN UVRE DES TECHNIQUES NUMERIQUES (METHODE DES ELEMENTS FINIS (F.E.M.) ET METHODE DES ELEMENTS FRONTIERE (B.E.M.)) POUR RESOUDRE LE PROBLEME POSE EN IMAGERIE D'IMPEDANCE. DES LOGICIELS DE SIMULATION ONT ETE ELABORES PAR F.E.M. ET B.E.M. ET LEURS RESULTATS COMPARES. UNE METHODE DE RECONSTRUCTION ORIGINALE, AXEE SUR LES TECHNIQUES DE CONTROLE OPTIMAL, EST PRESENTEE. LA REPRESENTATION GRAPHIQUE DU PARAMETRE DE CONTROLE PERMET LA LOCALISATION DE PERTURBATIONS DE CONDUCTIVITE DANS UN MILIEU DE CONDUCTIVITE CONSTANTE. LES RESULTATS OBTENUS PAR LES TECHNIQUES DE CONTROLE OPTIMAL PEUVENT ETRE UTILISES POUR DEVELOPPER D'AUTRES METHODES DE RECONSTRUCTION. UNE METHODE DE PERTURBATION SINGULIERE S'INSPIRANT DES TRAVAUX DE G. ALESSANDRINI EST AINSI PROPOSEE. UNE DEUXIEME APPROCHE CONSISTE A MODIFIER L'ALGORITHME DE WEXLER PERMETTANT AINSI D'ACCELERER CE DERNIER. ENFIN, L'INTRODUCTION DE BARRETTES DE DOUBLETS ELECTRIQUES DANS LE DOMAINE PEUT ETRE UTILISEE POUR PRODUIRE UNE IMAGE DE LA DISTRIBUTION DE CONDUCTIVITE DANS LE DOMAINE

Book Description
L'IMAGERIE D'IMPEDANCE EST UNE NOUVELLE TECHNIQUE D'IMAGERIE MEDICALE, QUI A POUR BUT DE RECONSTRUIRE LA DISTRIBUTION DE CONDUCTIVITE ELECTRIQUE AU SEIN D'UN MILIEU PHYSIOLOGIQUE. CE TRAVAIL A POUR BUT LE DEVELOPPEMENT D'ALGORITHMES DE RECONSTRUCTION EN IMAGERIE D'IMPEDANCE. IL EST AXE SUR L'APPLICATION DE LA METHODE DES ELEMENTS FRONTIERE. LA THEORIE DU POTENTIEL EST PRESENTEE ET SERT DE BASE MATHEMATIQUE DE LA METHODE DES ELEMENTS FRONTIERE. UN LOGICIEL DE SIMULATION, QUI RESOUT LE PROBLEME DIRECT, EST ELABORE. IL PERMET DE FOURNIR DES DONNEES EXACTES POUR LA RECONSTRUCTION ET DE TESTER DES TECHNIQUES POUR RESOUDRE DES DIFFICULTES RENCONTREES LORS DE LA MISE EN UVRE DE LA METHODE DES ELEMENTS FRONTIERE. UN ALGORITHME DE RECONSTRUCTION, ALGORITHME DE "LAYER-STRIPPING" BASE SUR LA DECOMPOSITION DU DOMAINE, EST DEVELOPPE. LA METHODE HUM (HILBERT UNIQUENESS METHOD) EST UTILISEE POUR RESOUDRE LE PROBLEME INVERSE MAL POSE DE L'IMAGERIE D'IMPEDANCE. QUELQUES ETUDES SONT EFFECTUEES SUR LA MISE EN UVRE NUMERIQUE DE CET ALGORITHME, DONT L'ESSENTIEL EST LA RESOLUTION DES PROBLEMES DE DIRICHLET GENERES PAR HUM ET LA PRESERVATION DE LA STABILITE DE L'ALGORITHME. DES SUGGESTIONS POUR LA SUITE DE L'ETUDE SONT DONNEES A LA FIN DU MEMOIRE AFIN DE OUVRIR DE NOUVELLES VOIES DE RECHERCHE

An Introduction to Mathematics of Emerging Biomedical Imaging
Author: Habib Ammari
Publisher: Springer Science & Business Media
ISBN: 3540795537
Category : Medical
Languages : en
Pages : 198
Book Description
Biomedical imaging is a fascinating research area to applied mathematicians. Challenging imaging problems arise and they often trigger the investigation of fundamental problems in various branches of mathematics. This is the first book to highlight the most recent mathematical developments in emerging biomedical imaging techniques. The main focus is on emerging multi-physics and multi-scales imaging approaches. For such promising techniques, it provides the basic mathematical concepts and tools for image reconstruction. Further improvements in these exciting imaging techniques require continued research in the mathematical sciences, a field that has contributed greatly to biomedical imaging and will continue to do so. The volume is suitable for a graduate-level course in applied mathematics and helps prepare the reader for a deeper understanding of research areas in biomedical imaging.
