Image-guided neurosurgery uses information from a wide spectrum of imaging methods which are registered to the patient's skull so that they correspond to the intraoperative macro- and microscopic view at the start of the operation. During neurosurgical intervention the correspondence between imaging and optical systems breaks because of brain shift down. In this study we demonstrate that Susceptibility-Weighted Imaging and automatic vessel segmentation can be used for visualization and segmentation of superficial cortical veins which can be used as additional reference system during operation.
