Module Description

This is a neurosurgical navigation system.


  • Patient to image registration
    • This is landmark registration. Register the patient coordinate system to the image coordinate system in Slicer3.
    • Find 4-6 fiducials (well spread) on the patient's head.
    • For each fiducial, find its patient coordinate (using a tracking device) and image coordinate in Slicer3. Input this point pair into NeuroNav module. Repeat the same process for all selected fiducials.
    • It's easy to remove one or all point pairs.
    • It's also easy to reset any registration used.
  • Surgical navigation
    • Locator Display
      • Choose a transform node.
      • Check to show the locator.
    • Tractography Seeding
      • Choose a fiducial list.
      • Check to seed tractography by fiducial
    • Driver
      • Check Locator to drive the navigation by Locator, or the tracking device.
      • Check User to stop the navigation.
      • Check Freeze to freeze the display.
      • Check Oblique to re-format image along oblique planes.
