Book Description
Here is the first book in 30 years to cover all diagnostic and therapeutic aspects of intramedullary spinal cord tumors (IMTs), a relatively rare but often misdiagnosed type of tumor. You will benefit from the largest personal collection of operated cases (171) ever assembled, as well as a review of 1,100 additional cases, making this the single most comprehensive book on IMTs available today. You will also appreciate the vital role of MRI in accurately diagnosing these tumors and review the latest technical refinements in surgical methods. Divided into three parts, the book begins with the diagnostic and therapeutic problems common to all intramedullary spinal cord tumors, then covers the histology of individual tumors, and finally examines the controversial value of radiotherapy in the treatment of both benign and malignant tumors in children and adults. Throughout, full-color illustrations depict anatomy from a surgical point of view.

Book Description
This book attempts to combine many different threads into a comprehensible whole. Since the subject is the Gamma Knife and the author is a neurosurgeon, the field of clinical interest is restricted to intracranial pathology. The discipline of radiosurgery now applies to patients who may reasonably be referred by internists, neurologists, otolaryngologists, endocrinologists and several others. Some of the topics, touched upon, such as stereotaxy and the construction of a radio surgical instrument are unfamiliar to the majority of medical men. Other topics, such as those pertaining to the reactions between radiation and living tissue, are not exactly unfamiliar and yet, for most of us, they are not comfortable areas of expertise: in that we have some basic knowledge but not enough to draw conclusions and interpret. In particular, it is not easy to answer the very sensible questions that patients ask, when being considered for this particular form of treatment. The author has attempted to describe the basic relevant phenomenology in terms that should be readily understandable to a non-specialist physician. To do this, he has been heavily dependent on the expertise of a number of mathematically sophisticated collaborators, who have checked his manuscript. They are named in the acknowledgments section. The relevance of the different sections of this book will naturally be assessed differently, according to the experience and interest of the reader. To simplifY access to the information that is required, the book is divided into three main sections.

Book Description
This publication aims to give comprehensive information on the methods of gamma knife radiosurgery and the results of treatment of the most frequent diagnoses using radiosurgery. A summarisation of existing knowledge and results obtained in gamma knife radiosurgery world-wide is based on experience with treatment of more than 13,500 patients over 20 years at Na Homolce Hospital, Prague. Besides detailing the basic data of Leksell gamma knife radiosurgery, this book also provides thorough technical description of former and existing gamma knife models, basic physics principles of gamma knife radiosurgery, calibration and quality assurance as well as standardised treatment procedures. The book is primarily intended for physicians, who, together with the patient decide on the most appropriate methods of treatment for each diagnosis. The publication can be also helpful to medical physicists who are involved in gamma knife radiosurgery and responsible for its calibration and quality assurance. Finally, it is also intended for patients who are looking for, if necessary, more comprehensive information on the radiosurgical treatment method for tumours and other brain disorders.

Book Description
L'imagerie par résonance magnétique de diffusion permet de mesurer l'intensité de la diffusion de l'eau dans plusieurs directions et révèle l'orientation locale des structures biologiques sous-jacentes, notamment l'orientation locale du réseau d'axones du cerveau. Une procédure appelée tractographie a pour objectif d'estimer la structure 3D de ce réseau d'axones à partir de l'information de diffusion. Les algorithmes de tractographie sont généralement contraints dans un sous-ensemble de l'image de diffusion où l'information mesurée est cohérente, par exemple par un masque de la matière blanche. L'algorithme de tractographie termine lorsqu'il atteint la frontière du masque. Quel effet le masque a-t-il sur les résultats produits par l'algorithme de tractographie ? Comment produire des résultats anatomiquement cohérents ? Dans ce mémoire, nous présentons des méthodes utilisant l'information des cartes probabilistes des tissus cérébraux provenant d'une image par résonance magnétique de type anatomique afin de produire une estimation la structure du réseau d'axones. L'objectif est d'estimer la structure 3D de la matière blanche en utilisant des connaissances a priori pour produire des résultats plus précis et cohérents. Notamment, nous proposons une approche reposant sur un filtre à particules pour modéliser la vraisemblance des structures estimées. Les résultats des méthodes développées sont comparés à d'autres méthodes sur des données synthétiques, sur des données cérébrales saines et sur des données cérébrales cliniques avec tumeurs cérébrales.

Book Description
The digital camera conceals remarkable technological innovations that affect the formation of the image, the color representation or automated measurements and settings. ** From photon to pixel photon ** describes the device both from the point of view of the physics of the phenomena involved, as technical components and software it uses. Based on the perceptual properties of the visual system as well as on standard transmission and representation, analyzes the solutions to meet the demands of the photographer on the development, contrast, white balance or stabilization of image. The advanced architectures adopted in mobile phones and developments of computational photography are also presented, foreshadowing the features of the future device.

Book Description
Skeletonization: Theory, Methods and Applications is a comprehensive reference on skeletonization, written by the world's leading researchers in the field. The book presents theory, methods, algorithms and their evaluation, together with applications. Skeletonization is used in many image processing and computer vision applications such as shape recognition and analysis, shape decomposition and character recognition, as well as medical imaging for pulmonary, cardiac, mammographic applications. Part I includes theories and methods unique to skeletonization. Part II includes novel applications including skeleton-based characterization of human trabecular bone micro-architecture, image registration and correspondence establishment in anatomical structures, skeleton-based fast, fully automated generation of vessel tree structure for clinical evaluation of blood vessel systems. - Offers a complete picture of skeletonization and its application to image processing, computer vision, pattern recognition and biomedical engineering - Provides an in-depth presentation on various topics of skeletonization, including principles, theory, methods, algorithms, evaluation and real-life applications - Discusses distance-analysis, geometry, topology, scale and symmetry-analysis in the context of object understanding and analysis using medial axis and skeletonization
