Advanced Neurosurgical Navigation


Book Description

An excellent account of the developments which have occurred in neuro-navigation, with thought-provoking insights into the wider applications of equipment...-Journal of Neurology, Neurosurgery and Psychiatry Today neurological surgery stands at a technological crossroad. Revolutionary advances in high-speed graphic computers, informatics, biotechnology, and robotics continue to change the field and open vast new possibilities for improved patient care. In this new book, the advances at work in everyday patient care, as well as revolutionary new systems, now under development are chronicled by the world-renowned team of neurosurgeons, computer scientists, software engineers and others who have led the technological transformations. The book includes full information on transferring medical data into mapping strategies, viewing the clinical applications of stereotaxis, and observing fascinating new image-guided neurosurgical procedures in actual clinical practice. Most importantly, there is a full comparison of the different systems now in use so that the surgeon can make intelligent decisions about which to purchase. Special features include: Innovative computer models that show normal neuroanatomy and its pathologic alterations in exquisite three-dimensional detail The value of fusing state-of-the-art imaging modalities to localize targets for stereotactic neurosurgery, including functional mapping of speech and motor areas, tumor localization, etc. Advanced intraoperative imaging techniques, including modern adaptations of stereotactic frames and real-time imaging (e.g. ultrasound, intraoperative MRI and CT) The potential of robotic manipulation in cutting edge imaging environments The pros and cons of many of the advanced neurosurgical navigation systems now in use and how each fits your needs The results of the new technology? Enormous improvements in surgical planning, execution, safety, and overall patient management -- plus flexibility in developing successful combination strategies that incorporate surgery with advanced neurosurgical and radiosurgical techniques. Complete with 547 illustrations, including 170 in full-color, the book goes further than any current work in documenting the evolution of modern neurosurgical navigation. All neurosurgeons, especially those working in modern intracranial, spinal and peripheral nerve techniques, will find it invaluable, as will neuroradiologists, radiation oncologists, general surgeons, and biomedical engineers. For the next generation in image-guided neurosurgery, this state-of-the-art work contains information not found elsewhere.




Mobile and Low-cost Hardware Integration in Neurosurgical Image-Guidance


Book Description

It is estimated that 13.8 million patients per year require neurosurgical interventions worldwide, be it for a cerebrovascular disease, stroke, tumour resection, or epilepsy treatment, among others. These procedures involve navigating through and around complex anatomy in an organ where damage to eloquent healthy tissue must be minimized. Neurosurgery thus has very specific constraints compared to most other domains of surgical care. These constraints have made neurosurgery particularly suitable for integrating new technologies. Any new method that has the potential to improve surgical outcomes is worth pursuing, as it has the potential to not only save and prolong lives of patients, but also increase the quality of life post-treatment. In this thesis, novel neurosurgical image-guidance methods are developed, making use of currently available, low-cost off-the-shelf components. In particular, a mobile device (e.g. smartphone or tablet) is integrated into a neuronavigation framework to explore new augmented reality visualization paradigms and novel intuitive interaction methods. The developed tools aim at improving image-guidance using augmented reality to improve intuitiveness and ease of use. Further, we use gestures on the mobile device to increase interactivity with the neuronavigation system in order to provide solutions to the problem of accuracy loss or brain shift that occurs during surgery. Lastly, we explore the effectiveness and accuracy of low-cost hardware components (i.e. tracking systems and ultrasound) that could be used to replace the current high cost hardware that are integrated into commercial image-guided neurosurgery systems. The results of our work show the feasibility of using mobile devices to improve neurosurgical processes. Augmented reality enables surgeons to focus on the surgical field while getting intuitive guidance information. Mobile devices also allow for easy interaction with the neuronavigation system thus enabling surgeons to directly interact with systems in the operating room to improve accuracy and streamline procedures. Lastly, our results show that low-cost components can be integrated into a neurosurgical guidance system at a fraction of the cost, while having a negligible impact on accuracy. The developed methods have the potential to improve surgical workflows, as well as democratize access to higher quality care worldwide.

fMRI


Book Description

Over the past two decades, fMRI has evolved into an invaluable clinical tool for routine brain imaging. This book provides a state of the art overview of fMRI and its use in clinical practice. Experts in the field share their knowledge and explain how to overcome diverse potential technical barriers and problems. Starting from the very basics on the origin of the BOLD signal, the book covers technical issues, anatomical landmarks, the full range of clinical applications, methods of statistical analysis, and special issues in various clinical fields. Comparisons are made with other brain mapping techniques, such as DTI, PET, TMS, EEG, and MEG, and their combined use with fMRI is also discussed. Since the first edition, original chapters have been updated and new chapters added, covering both novel aspects of analysis and further important clinical applications.
