Design and Implementation of Neurosurgery Navigation System


Article Preview

Neurosurgery navigation system consists of an image workstation, infrared optical positioning device and surgical instrument components. The system can use the patient CT/MRI images to develop preoperative surgical plan, choose the best surgical approach, in surgery it can rely on the three-dimensional patient images and optical locator, avoiding critical organizations and major functional areas, to make surgery smaller incisions, more thorough, more secure. The development consists of the following steps: image group management, displaying three orthogonal plane (transverse, sagittal, coronal), 3D reconstruction, image segmentation, three-dimensional drawing, 3D image space and operative space registration structure and function like image fusion. The main work and contribution of this paper is: 1. three dimensional reconstruction using linear interpolation instead of the bilinear interpolation, improve image clarity; 2. 3D rendering, pixel reconstruction filter using windowing, then directly draw pixels to improve rendering speed; 3. human-computer interaction by reducing the resolution to accelerate and achieve real-time three-dimensional rotation; 4. 3D image space and space operation registration method using landmarks, enhanced registration reliability; 5. with fusion of the function and structure image surgery can be used to avoid important functional areas, reduce the risk of disability.
