Distance Transform from a label map calculated by Steve Pieper using the NumpyScript module created by Luca Antiga. See Slicer3:Python for more info.
Exploring DTI visualization using the Neurosurgical Tutorial. A virtual probe (fiducial) was positioned in the motor cortex and used as a seed for tractography. The region adjacent to the tumor was used as a seeding area for a separate tractography, which is represented as thin lines with ellipsoid glyphs.

Partial image update using OpenIGTLink, February 2008
OpenIGTLink allows an external imaging scanner (Ultrasound/CT/MR) to update part of a volume, which has already been loaded on the Slicer. This is helpful if the imaging plane sweeps the subject, and images are transfered to the Slicer on-the-fly.
