Book excerpt: L'imagerie par résonance magnétique (IRM) est une technique d'imagerie relativement lente. Les mouvements du patient, en particulier en imagerie cardiaque et abdominale, constituent un obstacle important, venant perturber le processus d'encodage spatial nécessaire à la réalisation d'une image. Ces mouvements induisent des dégradations de l'image, appelées artéfacts, qui prennent des formes complexes du fait que cet encodage est réalisé dans un espace inhabituel (espace hybride Fourier/sensibilités d'antennes). Les méthodes généralement utilisées (apnée du patient, synchronisation de l'acquisition avec l'électrocardiogramme) sont imparfaites et ne sont pas toujours applicables. A l'aide d'une plateforme spécialement développée pour l'acquisition et l'analyse des données physiologiques pendant l'examen IRM, nous proposons d'intégrer des informations de mouvement a priori, à différents niveaux des processus d'acquisition et de reconstruction, avec un intérêt particulier pour la correction des erreurs d'encodage spatial. Nous construisons un modèle prédictif permettant d'estimer les champs de déplacements élastiques dans le plan ou le volume imagé, à partir de combinaisons linéaires des signaux fournis par la plateforme. Puis nous définissons un cadre de reconstruction généralisé permettant d'inclure les données de déplacements prédites par le modèle, afin de reconstruire une image corrigée, minimisant ainsi les artéfacts de mouvement. Les hypothèses et conditions de validité sont analysées, et le modèle prédictif ainsi que les différentes méthodes de reconstruction proposées sont validés sur des données réelles, cardiaques et abdominales, de sujets sains.

Available in PDF, EPUB and Kindle. Book excerpt: L'Imagerie par Résonance Magnétique (IRM) est de nos jours un puissant outil de diagnostic grâce à sa capacité à produire des images aussi bien morphologiques que fonctionnelles. Bien que la résolution temporelle se soit améliorée avec les techniques d'imagerie rapide et parallèle, les mouvements physiologiques du type cardio-respiratoire restent gênants et dégradent la qualité des images. L'apnée et la synchronisation sont les techniques les plus couramment utilisées. Celles-ci ont des limites et restent difficiles pour certains patients. Pour mettre en oeuvre l'imagerie adaptive qui consiste à intégrer les mouvements des patients dans les processus d'acquisition et de reconstruction, nous devons disposer de capteurs de mouvements compatibles IRM donnant la meilleure représentation du mouvement des organes. Différents types de capteurs et méthodes de validations ont été développés pour intégrer ces informations externes aux algorithmes de reconstruction. Chaque capteur conçu devait être non-invasif et compatible à l'environnement IRM (champ magnétique, gradients de champ magnétique, et ondes de radiofréquences). La conception des capteurs impliquait la mise en oeuvre d'outils d'acquisition, et des méthodes de tests et de validations. Différent concepts de capteurs ont été explorés et testés. La validation finale étant faite par l'intégration des signaux à l'imagerie adaptative qui conduit à un apport au niveau de la qualité de l'image et par conséquent une amélioration du diagnostic.

Available in PDF, EPUB and Kindle. Book excerpt: L'Imagerie par Résonance Magnétique (IRM) permet en un seul examen une analyse morphologique et fonctionnelle non invasive. Cependant, les mouvements physiologiques (cardiaques et respiratoires) ou involontaires du patient provoquent des artéfacts qui dégradent la qualité des images et réduisent la précision du diagnostic. Pour s'affranchir de ses mouvements, des méthodes telles que l'apnée ou la synchronisation sont habituellement utilisées en routines cliniques. Elles présentent des limites et restent contraignantes. Les techniques adaptatives intègrent les informations liées aux mouvements dans les processus d'acquisition et/ou de reconstruction des images afin de les compenser ou de les corriger. Elles nécessitent la connaissance de ces mouvements qui peuvent être estimés à l'aide de capteurs internes ou externes. Nous avons développé des capteurs à base d'accéléromètres, souvent utilisés pour estimer les mouvements, en respectant les contraintes imposées par l'environnement hostile de l'IRM et par l'utilisation en conditions cliniques. La compatibilité IRM ainsi que le fonctionnement en IRM, sur fantômes et volontaires sains, ont été évalués à l'aide de méthodes spécifiques mises en place. Deux autres capteurs basés sur des principes optiques ont également été testés, l'un sur fantômes uniquement et l'autre sur fantômes ainsi que sur volontaires sains. Enfin, les signaux obtenus par les différents capteurs ont été intégrés dans une méthode de correction rétrospective de mouvements développée au sein du laboratoire. L'objectif est de réduire les artéfacts de mouvements en intégrant les informations, issues des capteurs, lors de la reconstruction des images.

Book excerpt: This study of the brain stem and the cerebellum is the sequel to a previous study of the brain (cerebral hemispheres and diencephalon) [82]. The brain stem and cerebellum are dealt with here for the same purpose as was the brain in the previous work, i.e., to reach, step by step, knowledge that is comprehensive enough for an understanding of an atlas of sections and its clinical use. Following a brief survey of the methods used, the first chapter describes the brain stem and cerebellum surfaces as well as their location in the posterior cranial fossa. The second and the third chapter, respectively, describe the brain stem and cerebellum structures followed by brief surveys of their functions, enabling the reader to obtain an introductory view of the role of both the nuclei and fasciculi. The fourth chapter studies the brain stem vascular network in detail. Thus, this chapter sums up the results of research on brainstem superficial blood vessels and their intra nervous territories that were already presented in two previous works [79, 80]. By contrast, presentation of the cerebellar vascularization follows the previous literature.

Available in PDF, EPUB and Kindle. Book excerpt: Action selection is the task of doing the right thing at the right time. It requires the assessment of available alternatives, executing those most appropriate, and resolving conflicts among competing goals and possibilities. Using advanced computational modelling, this book explores cutting-edge research into action selection in nature from a wide range of disciplines, from neuroscience to behavioural ecology, and even political science. It delivers new insights into both detailed and systems-level attributes of natural intelligence and demonstrates advances in methodological practice. Contributions from leading researchers cover issues including whether biological action selection is optimal, neural substrates for action selection in the vertebrate brain, perceptual selection in decision making, and interactions between group and individual action selection. This first integrated review of action selection in nature contains a balance of review and original research material, consolidating current knowledge into a valuable reference for researchers while illustrating potential paths for future studies.

Available in PDF, EPUB and Kindle. Book excerpt: Depuis les premières descriptions cliniques datant de la fin du XIXe siècle, montrant l’intérêt médical relativement récent pour l’anxiété, les symptômes anxieux et les troubles anxieux, les concepts ont considérablement évolué au cours du XXe siècle pour aboutir aux classifications syndromiques en vigueur dans la nosographie actuelle. Pourtant, un certain nombre de questions demeurent, par exemple sur l’existence d’un continuum entre une anxiété normale et adaptative et une anxiété pathologique, la nature de la réactivité émotionnelle dans les troubles anxieux par rapport à celle décrite dans les troubles bipolaires, etc... La première partie d’ouvrage présente les diverses approches actuelles pour comprendre les troubles anxieux : modèles émotionnels, approche évolutionniste, psychodynamique, théorie de l’attachement, génétique, neurobiologie, neuropsychologie, électrophysiologie et neuro-imagerie. Sont ensuite exposés les différents troubles anxieux (attaque de panique, phobie sociale, trouble anxieux généralisé, hypocondrie, état de stress post-traumatique, TOC, etc.) et les associations co-morbides (dépression, conduites suicidaires, troubles bipolaires, addictions, etc...). Réunissant plus d’une quarantaine de spécialistes reconnus, riche d’une trentaine tableaux et schémas explicatifs et d’un index détaillé, cet ouvrage offre un état des connaissances et des recherches sur les troubles anxieux.

Book excerpt: The first clinical book on the hottest topic in radiation oncology, this timely teaching text offers step-by-step guidance in use of IMRT for cancers at each subsite of the head and neck. The book's high-end content gives readers the clinical decision-making expertise and technical proficiency to incorporate this state-of-the-art radiation treatment technique into practice. Unique to this text is the site-specific instruction on target determination and delineation, to ensure adequate treatment of the tumor target while sparing adjacent normal tissue. More than 250 detailed full-color and black-and-white illustrations clarify each step in clinical implementations of head and neck cancer treatment, especially IMRT. The book provides a concise, pertinent overview of the natural course, lymph node spread, diagnostic criteria, and therapeutic options for each head and neck cancer subsite. Numerous tables provide extensive summaries of the IMRT literature. Figures with succinct explanatory text demonstrate the patterns of direct tumor extension and nodal metastasis with which target volumes are determined and delineated. Clinical outcomes for patients treated with IMRT and with conventional techniques are also included.
