Practicability of magnetoencephalography-guided neuronavigation
Neurosurgical Review, 2002Magnetoencephalography (MEG) is a noninvasive option for localizing electroneurophysiological activity on the human cortex. The purpose of this study was to evaluate the practicability and reliability of MEG imaging integrated into a neuronavigation system to identify the sensorimotor cortex intraoperatively in patients with brain tumors in or near the

Classification and Analysis of the Errors in Neuronavigation
Neurosurgery, 2011There are many different types of errors in neuronavigation, and the reasons and results of these errors are complex. For a neurosurgeon using the neuronavigation system, it is important to have a clear understanding of when an error may occur, what the magnitude of it is, and how to avoid it or reduce its influence on the final application accuracy ...

Neuronavigation and Neuroendoscopy
1998In neuroendoscopy orientation and localisation of the endoscope’s tip is crucial. Additionally the endoscopic view can be obscured by solid structures or membranes.

Error Analysis in Cranial Neuronavigation
min - Minimally Invasive Neurosurgery, 2002Neuronavigation systems are now an important component of many modern neurosurgical treatment strategies. Their support facilities intraoperative orientation and makes neurosurgical operations more precise and less traumatic. Computer-aided neurosurgery is definitively not a temporary fashionable phenomenon, the concept of neuronavigation is here to ...

Functional Neuronavigation and Intraoperative MRI
2004Our concept of computer assisted surgery is based on the combination of intraoperative magnetic resonance (MR) imaging with microscope-based neuronavigation, providing anatomical and functional guidance simultaneously. Intraoperative imaging evaluates the extent of a resection, while the additional use of functional neuronavigation, which displays the ...

The impact of auditory feedback on neuronavigation
Acta Neurochirurgica, 2004We aimed to develop an auditory feedback system to be used in addition to regular neuronavigation, in an attempt to improve the usefulness of the information offered by neuronavigation systems.Using a serial connection, instrument co-ordinates determined by a commercially available neuronavigation system were transferred to a laptop computer.

Neuronavigation in Solitary Intracerebral Tumors
Journal of Neurosurgery, 2006Object. The goal of this study was to assess the impact of neuronavigation on the cytoreductive treatment of solitary contrast-enhancing intracerebral tumors and outcomes of this treatment in cases in which neuronavigation was preoperatively judged to be redundant. Methods. The authors conducted a prospective randomized study in which 45 patients, each

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.

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 ...
