Abstract :
At present, navigation path deviation caused by brain shift is the main factor that affects the accuracy of neurosurgical navigation. A new method of near infrared spectroscopy (NIRS) based neurosurgical navigation is presented in the paper. The correlation between NIRS optical parameters and medical image is used and the gray information of navigation path is regarded as the priori knowledge, the curvatures of sample-points are calculated by Hermite interpolation and the Mean Hausdorff distance as measurement criterion is used to match feature segments, then the real-time correction model is established. The algorithm of the given model is simple and can realize the best match within the error, and it provides an effective method for real-time navigation path correction.
