Andreas Bihlmaier describes a novel method to model dynamic spatial relations by machine learning techniques. The method is applied to the task of representing the tacit knowledge of a trained camera assistant in minimally-invasive surgery. The model is then used for intraoperative control of a robot that autonomously positions the endoscope. Furthermore, a modular robotics platform is described, which forms the basis for this knowledge-based assistance system. Promising results from a complex phantom study are presented.

This book focuses on a novel series of minimally invasive surgeries performed without gas insufflation and through a single port using the RoboSurgeon system. The concept of RoboSurgeon surgery involves a degree of "robotization" of the operator and participants. The operator, wearing a head-mounted display, uses robot-like handheld instruments. The endoscope is controlled by the movement of the operator's head using a gyro-sensor system. All participants wearing head-mounted displays can see the same images as the operator does. Although this surgery is mainly intended for urological cancers, it may also be applicable for various operations concerning other urological diseases, as well as for the treatment of diseases in different medical fields. The system has the potential to become the new standard in robotic surgery. This solution may be a boon to many patients around the world, especially in the aging societies many countries are now facing.

The future of surgery is intrinsically linked to the future of computational sciences: the medical act will be computer assisted at every single step, from planning to post-surgery recovery and through the surgical procedure itself. Looking back at the history of surgery, surgery practice has changed drama- cally with the extensive use of revolutionary techniques, such as medical imaging, laparoscopy, endoscopy, sensors and actuators, and robots. This trend is dependent on the use of computer processing, computational method, and virtualization. Computational surgery will not only improve the ef?ciency and quality of surgery, but will also give new access to very complex operations that require extreme precision and minimum intrusion. Such examples are today's inoperable cancer tumors that have invaded critical tissues or nervous centers. In order for this milestone to be reached quicker and more ef?ciently, surgeons will have to become very familiar with computing methods, such as image analysis, augmented re- ity, and/or robotics. It will be critical for surgeons to assimilate computers in their training, understand how computers work, understand the limitations/advantages of these computer tools, and be able to interpret computer imaging and simulations.

Endovascular neurosurgery is a recently introduced but rapidly evolving medical field, which uses minimally invasive interventions to treat major life-threatening vascular lesions of the Central Nervous System. Although its history counts less than 15 years of worldwide acceptance, it has rapidly displaced the traditional open neurosurgical techniques, being nowadays the first treatment choice for brain aneurysms and vascular malformations. Thus, the experience of each neuroendovascular center and performer is invaluable, offering the base for learning and teaching the new generation of interventionalists as well as for the evolvement of the method itself. This book presents the basic principles of endovascular neurosurgery starting from clinical cases. Through this close-to-clinical-reality-process, the reader will be able to more thoroughly understand the pathophysiology of the brain and spine vascular lesions as well as the decision-making strategy, related to the indications, endovascular methods and results, finding suggestions and solutions to his/her clinical questions and problems. Besides chapters devoted to CNS vascular embryology and anatomy, clinical cases organized in groups based on the treated lesions are introduced: ruptured and unruptured cerebral aneurysms of the anterior and posterior circulation, side-wall and bifurcation aneurysms, arteriovenous malformations (AVM), dural arteriovenous fistulae (dAVF), arterial stenosis and angioplasty as well as spinal vascular lesions. A separate chapter is devoted to the organization and necessary equipment of the angio room and the department offering neuroendovascular service. This volume will be of interest to neurosurgeons, interventional neuroradiologists, vascular surgeons, neurologists and ICU physicians as well as health care providers who are involved in the diagnosis and management of the vascular lesions of the brain and spine.
