In neurosurgery, high precision is required to precisely locate and operate within and around the brain. Often this type of surgery has both technical and anatomic challenges due to the need to reach deep into the chest cavity. Recent endoscopic surgical techniques have resolved many old problems while creating others, mainly due to the difficult orientation of using a 2-D imaging-based endoscopic procedure within a complex 3-D structure.
In computer-assisted neurosurgical procedures, having confidence in the accuracy of its measurement system is essential. Improvements in image guidance and surgical procedures using intra-operative imaging have been made possible by the adoption of computer assisted navigation. The position sensor is a critical component of any Computer-Assisted Neurosurgical system. Current technologies for position sensors are mechanical, optical (NDI Polaris Spectra™ and Polaris Vicra ®) and electromagnetic (NDI Aurora ®). The Polaris Position Sensor is mounted in the operating room, strategically positioned to maximize the visibility of the tracked instruments used during procedures. The NDI Polaris system is the optical system integrated into Computer-Assisted Neurosurgical systems by most of the world’s leading providers.
Benefits of Integration
Improvements in precise 3D measurement technology using NDI’s Polaris optical systems to carry out minimally invasive surgery techniques have allowed neurosurgeons to work with much greater accuracy and reduced risk. The application of computer-assisted image guidance technology to certain surgical procedures allows creation of new methods to address challenges by providing the needed navigation that ultimately improves accuracy, efficiency, and safety.
