Module Description

NeuroNav module is developed to guide neurosurgeons by images to perform surgical procedures in OR.

Usage

Regular Neurosurgical Navigation

Follow the following steps to make the module work properly:

1. Connect to a tracking source, which could be a tracking simulator or real tracking device such as NDI Aurora. The tracking source sends tracking data, i.e. the orientation and tip location of the probe, to Slicer at a defined rate.
2. Perform patient to image registration. Load preoperative image(s) or scene into Slicer. Choose 4-6 landmarks on the patient head and then find those points on the loaded image to perform the patient to image registration.
3. Execute surgical navigation. Navigation is driven by the tracking probe. As long as the probe tip moves within the tracking scope of the device, Slicer will update the image display to give a visual feedback to the neurorsurgeon. The image update will offer useful real-time guidance during the surgical procedure.

Integration with BioImage Suite and BrainLab

Integration of Slicer with BioImage Suite and BrainLab has been a recent successful example of collaboration between academia and industry. BioImage Suite is an integrated image analysis software suite developed at Yale University. BrainLab is an FDA approved neurosurgical navigation system. This integration will interface Slicer to the BrainLab system and allow neurosurgeons to use Slicer to perform some research in DTI visualization in OR while using BrainLab as the navigation system. Please check sections below for details.
