Infrared system for intraoperative digitization of laser and surgical instruments

摘要

Abstract: In neurosurgery localization is the process of matching the imaging data generated by an imaging modality such as computed tomography or magnetic resonance imaging with the patient's brain during surgery. This process is done intraoperatively using several methods. Using infrared signals is one of these methods. In this paper we describe a system that uses infrared as a tool to determine a position in 3D space. We also describe a computer- based neurological image data acquisition and correlation system that assists the neurosurgeon with preplanning, simulation, and optimization of the surgical procedures and shows the safest approach to lesions. We describe localization in laser resection procedures for both contact (Nd-YAG) and non-contact (CO$-2$/) lasers.!5
