InVesalius has currently, beyond the functionalities related to medical imaging, a special feature for neuronavigation, called InVesalius Navigator. InVesalius Navigator allows accurate and real-time localization of surgical and interventional instruments with respect to neuronal anatomy, visualized in magnetic resonance or computed tomography images. The neuronavigation feature requires a connection with a spatial tracking devices. Currently, InVesalius supports the three electromagnetic models FASTRAK, ISOTRAK II and PATRIOT, produced by Polhemus (Colchester, VT, USA) and the optical device MicronTracker Sx60 model from ClaroNav (Toronto, Canada). InVesalius Navigator has an intuitive, real-time guiding interface to allow the positioning of transcranial magnetic stimulation (TMS) coils with respect to a user-defined target. Moreover, TMS target coordinates representing stimulation sites can be exported for analysis in third-party software. Additionally to TMS experiments, InVesalius Navigator has been used for surgical planning strategies using 3D printed patient-specific models.
