Preoperative 3D planning in cranial neurosurgery

A very detailed resource regarding preoperative planning in cranial surgery including:
• Lesion localisation and measurements
• Planning of the craniotomy in neuroncology, vascular, skull base, trauma and reconstruction
cases
• Simulation of the approach, and craniotomy
• Skull stripping technique
The original paper is for OsiriX Software (osirix-viewer.com), but the same principles can be applied to other 3D DICOM viewers such as:
• Horos viewer: (horosproject.org)
• 3D Slicer: (slicer.org)
• Radiant: (radiantviewer.com)
