Stereovision to MR image registration for cortical surface displacement mapping to enhance image-guided neurosurgery

摘要

Purpose:A surface registration method is presented to align intraoperative stereovision (iSV) with preoperative magnetic resonance (pMR) images, which utilizes both geometry and texture information to extract tissue displacements as part of the overall process of compensating for intraoperative brain deformation in order to maintain accurate neuronavigational image guidance during surgery.
