Child's Nervous System, 1999
The fact that the visualization process has been deferred since MRI and CT scanning have become the imaging standards for today's neurosurgeons has led to the importance of developing a tool for testing and teaching young pediatric neurosurgeons in the future. Navigation and teaching in a virtual reality model seems a sound solution.

Tractography in functional neuronavigation
S.S. Korsakov Journal of Neurology and Psychiatry, 2023The review addresses the combined use of tractography and neuronavigation. Fundamentals of diffusion tensor imaging are given, technical aspects of fiber tracking in general and in depicting separate subcortical tracts are described. Main advantages of the method and possible causes of errors are highlighted.

Abstract The relatively high focality of transcranial brain stimulation requires accurate targeting of the fields delivered to the brain in order to stimulate the neural circuits that mediate the intended effect while reducing the unintended exposure of other brain areas.

Neuronavigation-assisted Cranial Reconstruction
Neurosurgery, 2004Cranial defects resulting from congenital deformities, ablative resection of osseous tumors, traumatic injury, and destructive infectious lesions are often severe enough to warrant surgical reconstruction. In particular cases, satisfactory cosmetic results may be difficult to achieve because of the extent and location of the lesion.We evaluated the ...

Neuronavigation in Skull Base Tumors
min - Minimally Invasive Neurosurgery, 2005Computer-assisted neuronavigation was used in 87 cases of skull base lesions (SBLs). Preoperative planning and intraoperative identification of anatomic landmarks is especially important in SBLs since it helps to avoid or minimize surgical morbidity and mortality. In this study, we assessed the accuracy and the clinical usefulness of a frameless system

Neuronavigator-Guided Cerebral Biopsy
1993Neuronavigators are new dynamic interactive instruments that use on-line computers to orient imaging data to the surgical field and guide the neurosurgeon to his target. We have been working since 1987 on a neuronavigator that serves not only as a precise pointer, but also as a dynamic arm that can be used to hold instruments, such as biopsy guides ...

Neuronavigation – Impact on Operating Time
Stereotactic and Functional Neurosurgery, 1997It is uncertain whether the use of image-guided surgery has an influence on operating time. We prospectively studied the time requirements which have to be invested for using image-guided surgery and performed a comparison of operating room times from 125 matched pairs of image-guided and conventional operations. Our study revealed that neuronavigation

Neuronavigational Epilepsy Focus Mapping
2001The localization of a seizure focus for resective surgery often requires invasive monitoring for precise localization of the target as well as structures to avoid. We report on the use of intra-operative surgical navigation to precisely localize and co-register subdural electrodes to regions of know radiographic pathology.

Frameless Neuronavigation in Modern Neurosurgery
min - Minimally Invasive Neurosurgery, 1995A fundamental effort in neurosurgery is to reduce surgical trauma. Microneurosurgical technique combined with precise localization of lesions, can minimize the invasiveness of neurosurgical procedures. This report summarizes the utility of frameless neuronavigator systems and examines their value in reducing operative invasiveness.

Clinical Experiences in Neuronavigation
Stereotactic and Functional Neurosurgery, 2001We have successfully used a navigation system in more than 120 neurosurgical operations for past two years. The neuronavigation system provides high levels of mechanical accuracy in surgical localization, especially for small deep-seated masses or epileptic foci, surgical planning for intrinsic and extrinsic brain tumors, and arteriovenous malformation
