Hybrid Frame-based Neuronavigation
نویسنده
چکیده
Sun et al. have invented a new stereotactic instrument[1], which is thought to bridge the differences between frameless and frame-based techniques. It consists of a stereotactic frame, which is attached to the skull in a manner comparable to classical stereotactic frames. Instead for guidance of a linear instrument, as for example in the case of a frame-based stereotactic biopsy, it is connected with a visualization system for guidance of multiple instruments, which can be moved in every possible direction. The accuracy is said to be approximately 2 mm, which is again somewhere between the accuracies of frame-based (less than 1 mm) and frameless systems (between 1 and 5 mm).

A New System for Neuronavigation and Stereotactic Biopsy Pantograph Stereotactic Localization and Guidance System
Everyday, neurosurgeons face the problem of orientation within the brain but the advent of stereotactic surgery and neuronavigation have solved this problem. Frame-based stereotactic systems (FBSS) and neuronavigation systems have their own strengths and priority and pitfalls, which were the main driving force for us to design a new system. This hybrid system comprises three main parts: main fr...

متن کاملNeuronavigation-guided Frameless Stereoelectroencephalography (SEEG)
Stereoelectroencephalography (SEEG) is an invasive surgical procedure used to identify epileptogenic zones. The combination of both subdural grids and depth electrodes (DEs) is currently used for invasive intracranial monitoring in many epilepsy centers. To perform DE implantation, some centers use frame-based stereotactic techniques and others use stereotactic robotic techniques. However, not ...
متن کاملThe advantages of frameless stereotactic biopsy over frame-based biopsy
Health technology The use of frameless stereotactic biopsy was investigated. The technique consisted of a neuronavigation system, based on an infrared LED-based system (Easy Guide Neuro, Philips Medical Systems), and a novel stereotactic guide that was adaptable to a variety of instruments. The developed guide was freely adjustable to reach the entire cranium and would lock in place rigidly, al...
متن کاملFrameless Stereotactic Neuronavigation for Space Occupying Lesions
Introduction Prior to the widespread advent of frameless stereotaxy, intracranial tumour surgery relied upon a 3-D conceptualisation of anatomy from pre-operative imaging. External anatomical landmarks such as the coronal suture and auricle helped guide the placement of a craniotomy. Bone flaps were often planned with a margin for error, particularly when locating non-lobar tumours. The choice ...
