Clinical evaluation of the accuracy of an invasive frame designed for stereotactic intracranial radiosurgery treatment with helical tomotherapy.
AIMS AND BACKGROUND The study focused on the evaluation of the accuracy of intracranial stereotactic radiosurgery treatments delivered with helical tomotherapy by means of the InterFix™ Radiosurgery kit. METHODS AND STUDY DESIGN Twenty-two patients received stereotactic radiosurgery treatments with single fraction dose ranging from 13 to 20 Gy depending on diagnosis. Megavoltage computed tomo...
متن کاملEvaluation of accuracy and reproducibility of a relocatable maxillary fixation system for fractionated intracranial stereotactic radiation therapy
INTRODUCTION Accurate localisation is an essential component for the delivery of intracranial stereotactic treatment. For fractionated stereotactic radiotherapy, we compared the daily localisation accuracy of a standard thermoplastic mask with a new maxillary fixation device (MFD). METHODS Daily pre-treatment kV cone-beam computed tomography (CBCT) scans of 23 patients (12 localised in the MF...
متن کاملDevelopment of A Head Docking Device for Linac-based Stereotactic Radiosurgery System to be Installed on Neptun 10 PC Linac
Introduction: Stereotactic radiosurgery is a technique for the treatment of intracranial lesions with highly collimated x-ray beam. Linac-based radiosurgery is currently performed by two techniques: couch or pedestal mounted. In the first technique, a device is required to affix patient's head to a couch and moreover to translate it accurately. Structure of suc...
متن کاملStereotactic radiosurgery of intracranial arteriovenous malformations.
Stereotactic radiosurgery for intracranial arteriovenous malformations (AVMs) has been performed since the 1970s. When an AVM is treated with radiosurgery, radiation injury to the vascular endothelium induces the proliferation of smooth muscle cells and the elaboration of extracellular collagen, which leads to progressive stenosis and obliteration of the AVM nidus. Obliteration after AVM radios...
متن کاملA virtual frame system for stereotactic radiosurgery planning.
PURPOSE We describe a computerized (or virtual) model of a stereotactic head frame to enable planning prior to the day of radiosurgery. The location of the virtual frame acts as a guide to frame placement on the day of the procedure. METHODS AND MATERIALS The software consists of a triangular mesh representation of the essential frame hardware that can be overlaid with any MR scan of the pati...
