Surgical navigation is an interactive localization technique to establish a relation between surgical instruments, patient’s anatomy, and additional data (e.g. preoperative or intraoperative patient images or atlases). The first attempt to localize structures within the brain using orientation points on the skull surface and a standardized brain atlas was done at the beginning of 20th century (...

A variety of surgical treatments for intractable epilepsy with hypothalamic hamartoma (HH) are described, although most are derived from limited patient experience gathered from several centres. We describe the results of transcallosal resection of HH in 29 consecutive patients undergoing surgery at one centre. Twenty-nine patients aged 4-23 years (mean 10 years) underwent HH surgery with a min...

Introduction MRI Quality Control (QC) testing involves monitoring of system performance using phantom scans. While the most direct QC is provided by an attentive technician continuously monitoring the clinical images for artefacts, a regular phantom scan followed by quantitative analysis provides the ability to detect subtle changes in image quality at an early stage, and to monitor long-term t...

Neurosurgery is not an easy job. This is statement is commonsense even among laypeople, as can be noticed by the widespread use of the expression “it’s hardly brain surgery” – in the meaning that an apparently complicated task or procedure is actually not as difficult as it may seem to non-experts (another all around idiom with similar meaning is “it’s hardly rocket science” – note in both case...

This book is a multiauthored collection of 20 chapters, divided into 2 parts, reviewing the techniques (part 1, 14 chapters) and current applications (part 2, 6 chapters) for different image-guided neurosurgical and endovascular procedures. A better title might have been “Image-Guided Neurosurgery” or “Image-Guided Neurointervention.” The range of procedures considered to be minimally invasive ...

The purpose of this work is to prospectively assess the setup accuracy that can be achieved with a stereotactic body localizer (SBL) in immobilizing patients for stereotactic intensity-modulated radiotherapy (IMRT) for prostate cancer. By quantifying this important factor and target mobility in the SBL, we expect to provide a guideline for selecting planning target volume margins for stereotact...
