Abstract

In this prospective study we measured the calculated registration error and the application accuracy of laser surface registration for intracranial image-guided surgery in a clinical setting. Surface registration was performed using a Class I laser device. Application accuracy was 2.4±1.7 mm. It was higher for the surgical field of frontally located lesions (mean, 1.8±0.8 mm) as compared with temporal, parietal, occipital, and infratentorial lesions (mean, 2.8±2.1 mm). We found laser scanning for surface registration an accurate, robust, and easy-to-use method for patient registration in image-guided neurosurgery.
