Stereotactic Neurosurgery

Introduction

The Stereotactic Neurosurgery is a field of Neurosurgery which is based on the use of special mechanical devices currently called "helmets" consisting essentially of a metal frame which is fixed to the head of the patient, in order to achieve a precise point of the brain ("target ") spatially defined by a set of three Cartesian coordinates.

With various types of probes can perform diagnostic or therapeutic maneuvers in small areas of the brain located deep, limiting the surgical aggression to a simple drill hole and causing minimal trauma to adjacent brain tissue (Townsend, 2001).

A fundamental boost to stereotactic techniques came by ...
