Intracerebral hemorrhage is a common disease. We give a short review of primary haemorrhages under neurosurgical aspects. Neurological symptoms depend on localisation and size of the hematoma. Only a subgroup of intracerebral haemorrhages is treated surgically. The STICH-trial tried to differentiate, in which cases the hematoma should be removed surgically. Surgical treatment could be performed...

Neurosurgeons have long used various image-guided systems, such as fluoroscopy, ultrasound, and threedimensional (3-D) stereotaxy in an attempt to more accurately localize intracranial targets (34). The development of advanced neuroimaging techniques over the years has provided the neurosurgeon with increasingly more accurate and precise tools to aid in the microsurgical treatment of intracrani...

Background and Aim: Numerous efforts over the past century have been performed. Various innovation techniques are increasingly gaining attention and gradually established the foundation of recent significant developments in the world of neurosurgery, among which varied stereotactic neuro-navigation designs and other novel emerging systems are being quotidian developed. This narrative review ai...

We describe a computer program which facilitates the analysis of a series of C.T. scans made while a stereotaxic fram fixed to the patient. program has 2 modes of operation: The operator may select a region and determine the three-dimensional frame coordinate. The operator may select a set of frame coordinates and have the computer program display these at the appropriate sites on C.T. scans. I...

In this paper we address the problem of the pose estimation based on multiple geometrical features for monocular endoscopic vision with laparoscopes and for stereotaxy with CT scanners. Partial and full pose estimation (6 dofs) are considered with applications to minimally invasive surgery. At the University of Strasbourg, we have been developing a set of techniques for assisting surgeons in na...

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 ...

BACKGROUND Tracking of post-registration head motion is one of the major problems in frameless stereotaxy. Various attempts in detecting and compensating for this phenomenon rely on a fixed reference device rigidly attached to the patient's head. However, most of such reference tools are either based on an invasive fixation technique or have physical limitations which allow mobility of the head...
