Book Synopsis Planification inverse avec approche par segments anatomiques et non anatomiques en radiothérapie externe appliquée à l'ORL by : Charles Lavoie
Download or read book Planification inverse avec approche par segments anatomiques et non anatomiques en radiothérapie externe appliquée à l'ORL written by Charles Lavoie and published by . This book was released on 2006 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans le but d'offrir des plans de qualités dosimétriques comparable au plan d'IMRT, l'ajout de segments prédéterminés non anatomiques a été réalisé pour les plans balistiques. Avec des corrections manuelles du MLC, il s'est avéré possible de générer des plans comparables à ceux réalisés en IMRT, et ce avec moins de segments et d'UM. Au total, 11 cas ont été réalisés selon cette approche. De plus, la robustesse des deux méthodes de planification à l'amaigrissement du patient et aux erreurs de position du collimateur multilame a été abordée. En IMRT classique, aucune optimisation de l'orientation des faisceaux est réalisée, une distribution coplanaire équidistante est employée. L'impact de l'utilisation des incidences, suggérées par Ballista, a aussi été étudié sur les plans d'IMRT.
Book Synopsis Dosimétrie cardiovasculaire à l'aide de fantômes numériques hybrides en radiothérapie externe by : Alexandra Moignier

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les atteintes cardiovasculaires consécutives à la radiothérapie font partie des effets secondaires tardifs soulevant de nombreuses interrogations au sein de la communauté scientifique, notamment du point de vue de la relation dose-Effet et des effets concomitants d'autres facteurs de risque (chimiothérapie, cholestérol, âge, tension artérielle,...). Les coronaropathies post-Radiques sont une des principales causes de morbidité cardiaque. Cependant, l'étude des doses reçues par les coronaires lors d'une radiothérapie requiert des approximations importantes, notamment d'un point de vue morphologique. Pour les études rétrospectives avec des dossiers médicaux anciens, les informations anatomiques sont réduites à des radiographies orthogonales et quelques contours au simulateur. Pour les dossiers médicaux plus récents, l'utilisation de l'imagerie scanner pour la planification de traitement permet la considération d'une anatomie 3D, toutefois extrêmement limitée pour les coronaires en raison d'une résolution et d'un contraste trop faibles. Par ailleurs, lors de la planification de traitement des patients traités actuellement, les doses reçues par les artères coronaires sont rarement quantifiées en clinique, et quand elles le sont, c'est au moyen d'une segmentation par a priori anatomique. Ce travail de thèse propose une utilisation originale des fantômes numériques hybrides afin d'étudier les doses aux coronaires dans le cadre de radiothérapies du sein gauche et du lymphome de Hodgkin.Au cours de la thèse, une méthode d'insertion de fantômes numériques hybrides au format DICOM dans le système de planification de traitement a été développée et validée. Elle a été adaptée et testée avec des informations anatomiques limitées aux radiographies comme c'est le cas pour les dossiers médicaux anciens, pour des traitements du sein gauche.La méthode a également été adaptée pour effectuer des reconstructions dosimétriques précises aux artères coronaires de patients traités par radiothérapie pour un lymphome de Hodgkin médiastinal, ayant bénéficié d'un suivi cardiovasculaire incluant le diagnostic de sténoses coronariennes à l'aide d'un coroscanner. Par une étude cas-Témoin, le risque de sténoses à un segment d'artère coronaire donné a été évalué comme étant multiplié par 1,049 à chaque Gray aditionnel sur la dose médiane au segment d'artère coronaire.Pour les dossiers actuels, les incertitudes associées à l'approche de segmentation par a priori anatomique des artères coronaires ont été estimées dans le cadre du traitement du sein gauche, en simulant différentes topologies réalistes d'artères coronaires dans un unique thorax et en évaluant les doses, pour une balistique donnée avec et sans irradiation de la chaîne mammaire interne. La variabilité inter-Topologique de la dose moyenne à l'artère coronaire la plus irradiée, l'interventriculaire antérieure, a été estimée à respectivement 35%et 19% avec et sans irradiation de la chaîne mammaire interne tandis qu'avec la dose aux 2% du volume de l'artère interventriculaire les plus irradiés, cette variabilité est respectivement de 76% et 49%.Enfin, l'ordre de grandeur des écarts entre des mesures par films radiochromiques et des calculs de dose du système de planification de traitement ISOgray en bordure de champ et hors du champ a été évalué pour des configurations simple (fantôme physique homogène parallélépipédique, champ carré ouvert) et complexe (fantôme physique anthropomorphe avec hétérogénéités, faisceaux tangentiels rectangulaires avec filtres en coin). Ces écarts sont jugés significatifs essentiellement en bordure de champ quelle que soit la configuration.

Book Synopsis Cambridge Yearbook of European Legal Studies, Vol 13, 2010-2011 by : Catherine Barnard
Download or read book Cambridge Yearbook of European Legal Studies, Vol 13, 2010-2011 written by Catherine Barnard and published by Bloomsbury Publishing. This book was released on 2011-12-15 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.

Download or read book The Western Home written by Orm Øverland and published by University of Illinois Press. This book was released on 1996 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Western Home: A Literary History of Norwegian America is a history of American literature. It is different from other histories of American literature in that the language of the writers and their readers was not English. There have been studies of American authors who have used languages such as French, German, Spanish, or Swedish, but this is the first comprehensive history of any literature written and read in the United States in another language than English. Indeed, most histories of American literature are based on the theory that English is the only American literary language. Such a theory, however, dismisses the fact that English has in periods been a minority language in many areas. In this book American literature is the literature of people who are American by choice or by birth regardless of the language they may have used. This book demonstrates that Norwegian has indeed been an American literary language and that many of the American writers in this language deserve our attention.

Download or read book Unidentified written by Robert Salas and published by Career Press. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1969 the U.S. Air Force issued a statement that read' "No UFO reported, investigated and evaluated by the Air Force was ever an indication of threat to our national security." This statement is patently false. It has been proven untrue by the testimony of many military officers and airmen and documentation of incidents involving UFOs and nuclear weapons, testimonies of which the U.S. Air Force was fully aware. Unidentified details many of these testimonies, some for the first time. As partial justification for its position, the Air Force cites a University of Colorado study that was contracted and paid for by federal funds. Unidentified reveals how this study was actually just another part of the plan to cover up the reality of the UFO phenomenon. For the first time, Unidentified publishes evidence that the investigators for the Colorado study knew about the UFO-related missile shutdown incidents but did not investigate them or include them in their final report.
Book Synopsis New Historicism and Cultural Materialism by : John Brannigan
Download or read book New Historicism and Cultural Materialism written by John Brannigan and published by Bloomsbury Publishing. This book was released on 2016-02-12 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: New historicism and cultural materialism emerged in the early 1980s as prominent literary theories and came to represent a revival of interest in history and in historicising literature. Their proponents rejected both formalist criticism and earlier attempts to read literature in its historical context and defined new ways of thinking about literature in relation to history. This study explains the development of these theories and demonstrates both their uses and weaknesses as critical practices. The potential future direction for the theories is explored and the controversial debates about their validity in literary studies are discussed.
