This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'Imagerie par Résonance Magnétique (IRM) nécessite des outils pour gérer le mouvement physiologique et autre du sujet. La création des images par l'IRM comporte trois étapes: l'acquisition de données avec une séquence d'impulsions, la reconstruction d'images, et le post-traitement. Les techniques adaptatives de reconstruction d'images visent à intégrer des informations liées au mouvement dans le processus de génération d'images à partir de données acquises, ceci dans le but de compenser les artéfacts et problèmes provoqués par le mouvement. L'IRM dynamique avec rehaussement de contraste est une technique destinée à l'estimation de la fonction des organes, en suivant le passage d'un produit de contraste dans le corps. Les problèmes dus au mouvement, surtout dans l'application thoraco-abdominale de cette technique, se présentent sous forme d'artéfacts de mouvement et de décalages. Une nouvelle méthode de reconstruction d'images, DCE-GRICS (Reconstruction généralisée dynamique avec rehaussement de contraste par inversion d'un système couplé), a été développée pour résoudre ces problèmes. Le mouvement est estimé avec un modèle linéaire non rigide basé sur les signaux physiologiques issus de capteurs externes. Les changements d'intensité causés par le passage de l'agent de contraste sont rendus avec un modèle linéaire de changement de contraste basé sur le fonctions B-spline. Cette méthode a été appliquée et validée sur l'imagerie de la perfusion myocardique. Les inexactitudes causées par le mouvement dans les courbes intensité-temps sont compensées, afin de rendre plus fiable le post-tratement des courbes pour l'estimation de la perfusion myocardique.

Download or read book Imaging of the Larynx written by Robert Hermans and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Notwithstanding the important role of direct clinical and endoscopic examination in modern management of pathological conditions of the larynx, radiological study the and, more specifically, cross-sectional imaging by CT and MRI make definite diagnostic contributions by virtue of their potential to display superbly the deeper extent of laryngeal lesions. Indeed, remarkable progress has been achieved during recent years in CT and MRI techniques as applied to the neck region. This book sets out to provide a sorely needed update of our knowledge of the diagnostic potential of these cross-sectional methods and constitutes a very welcome addition to our series "Medical Radiology", which aims to cover all important clinical imaging fields of modern diagnostic radiology. It will be of great interest to general and head and neck radiologists as well as to ENT surgeons and radiotherapists. Professor R. Hermans and the other distinguished contributors to this work are internationally renowned experts in the field and they have accumulated vast experi ence and a wealth of radio-pathological knowledge of the larynx over the years. I would like to congratulate them most sincerely for this outstanding volume, its comprehensive contents and its superb illustrations. I hope that this book will meet with the same great success as previously published volumes in the series. I would appreciate any constructive criticism that might be offered.

Download or read book Bone Quantitative Ultrasound written by Pascal Laugier and published by Springer Nature. This book was released on 2022-05-05 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many significant achievements in new ultrasound technologies to measure bone and models to elucidate the interaction and the propagation of ultrasonic waves in complex bone structures have been reported over the past ten years. Impaired bone remodeling affects not only the trabecular compartment but also the cortical one. Despite the crucial contribution of the cortical structure to the whole bone mechanical competence, cortical bone was understudied for a long time. A paradigm shift occurred around 2010, with a special focus placed on the importance of cortical bone. This has sparkled a great deal of interest in new ultrasound techniques to assess cortical bone. While our book ‘Bone Quantitative Ultrasound’ published in 2011 emphasized techniques to measure trabecular bone, this new book is devoted for a large part to the technologies introduced recently to measure cortical bone. These include resonant ultrasound spectroscopy, guided waves, scattering, and pulse-echo and tomography imaging techniques. Instrumentation, signal processing techniques and models used are detailed. Importantly, the data accumulated in recent years such as anisotropic stiffness, elastic engineering moduli, compression and shear wave speeds of cortical bones from various skeletal sites are presented comprehensively. A few chapters deal with the recent developments achieved in quantitative ultrasound of trabecular bone. These include (i) scattering-based approaches and their application to measure skeletal sites such as the spine and proximal femur and (ii) approaches exploiting the poro-elastic nature of bone. While bone fragility and osteoporosis are still the main motivation for developing bone QUS, this Book also includes chapters reporting ultrasound techniques developed for other applications of high interest such as 3-D imaging of the spine, assessment of implant stability and transcranial brain imaging. This book, together with the book ‘Bone Quantitative Ultrasound’ published in 2011 will provide a comprehensive overview of the methods and principles used in bone quantitative ultrasound and will be a benchmark for all novice or experienced researchers in the field. The book will offer recent experimental results and theoretical concepts developed so far and would be intended for researchers, graduate or undergraduate students, engineers, and clinicians who are involved in the field. The book should be considered as a complement to the first book publisher in 2011, rather than a second edition, in the sense that basic notions already presented in the first book are not repeated.

Download or read book MRI of the Lung written by Hans-Ulrich Kauczor and published by Springer Science & Business Media. This book was released on 2008-11-12 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade significant developments have been achieved in the field of magnetic resonance imaging (MRI), enabling MRI to enter the clinical arena of chest imaging. Standard protocols can now be implemented on up-to-date scanners, allowing MRI to be used as a first-line imaging modality for various lung diseases, including cystic fibrosis, pulmonary hypertension and even lung cancer. The diagnostic benefits stem from the ability of MRI to visualize changes in lung structure while simultaneously imaging different aspects of lung function, such as perfusion, respiratory motion, ventilation and gas exchange. On this basis, novel quantitative surrogates for lung function can be obtained. This book provides a comprehensive overview of how to use MRI for imaging of lung disease. Special emphasis is placed on benign diseases requiring regular monitoring, given that it is patients with these diseases who derive the greatest benefit from the avoidance of ionizing radiation.
Download or read book Language in Our Brain written by Angela D. Friederici and published by MIT Press. This book was released on 2017-11-16 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive account of the neurobiological basis of language, arguing that species-specific brain differences may be at the root of the human capacity for language. Language makes us human. It is an intrinsic part of us, although we seldom think about it. Language is also an extremely complex entity with subcomponents responsible for its phonological, syntactic, and semantic aspects. In this landmark work, Angela Friederici offers a comprehensive account of these subcomponents and how they are integrated. Tracing the neurobiological basis of language across brain regions in humans and other primate species, she argues that species-specific brain differences may be at the root of the human capacity for language. Friederici shows which brain regions support the different language processes and, more important, how these brain regions are connected structurally and functionally to make language processes that take place in milliseconds possible. She finds that one particular brain structure (a white matter dorsal tract), connecting syntax-relevant brain regions, is present only in the mature human brain and only weakly present in other primate brains. Is this the “missing link” that explains humans' capacity for language? Friederici describes the basic language functions and their brain basis; the language networks connecting different language-related brain regions; the brain basis of language acquisition during early childhood and when learning a second language, proposing a neurocognitive model of the ontogeny of language; and the evolution of language and underlying neural constraints. She finds that it is the information exchange between the relevant brain regions, supported by the white matter tract, that is the crucial factor in both language development and evolution.
