Introduction

  • This is an advanced topic presentation on Slicer abilities. The intention is to familiarize the NA-MIC community with Slicer abilities.
  • You have mastered the introductions and you are hungry for more.... :)
    • This means that we expect you to at least have worked through the Core Tutorials before this class.
  • Ron and the creators of modules will show you advanced capabilities in Slicer 3.6

Logistics

  • What: Advanced capabilities in Slicer
  • Who: All the new DBP engineers, all the participants new to NA-MIC
  • When: Monday afternoon: 3pm through 5pm
  • Where: Main Event Room

Data

  • Image data used

  • Case 40 from the fMRI neurosurgery data set on central.xnat.org

  • T1 Weighted SPGR image
