One of my primary research areas is the automated extraction of surface mesh representations of the brain. This was the central topic of my dissertation work, and it led to the development of the first version of BrainSuite (Shattuck and Leahy, 2002). We have continued to refine the workflow since the initial release, with improvements to its speed, automation, and reliability. For a typical ~1mm^3 T1-weighted MRI, the current processing sequence can be completed in about 15 mins on a current desktop or laptop computer.
