Tutorial Data

• The 2D brain image used in this example is distributed as part of Slicer4, and is located in Slicer4/Testing/Data/Input/brainSliceDOUBLE.mha

Tutorial Steps

1. Load brainSliceDOUBLE.mha:
   • File -> Add Volume
2. Open the Interactive PDF Segmenter module
   • 
3. Set the input and output volumes
   • Input Volume 1: brainSliceDOUBLE
   • Input Volume 2 (optional): None
   • Input Volume 3 (optional): None
   • Output Volume: Create new volume
     • Creates a new volume called "Volume": this will hold the final segmentation
4. Set the view layout to "Red slice only"
   • 
   • 
5. Create the label map roughly outlining the structures to be segmented and the background
   • Label Map: Create new volume
     • Creates a new volume called "Volume1": this will hold the input label map
   • A small version of Slicer's Editor module is embedded into the Interactive PDF Segmenter
   • Create a label map roughly outlining the structures of interest and the background by using the paint, erase and threshold functions
     • Click on the "Paint" button to begin editing
     • Use a different label color for each structure of interest: choose the label by clicking the colored push button
   • 
     • Create a label for the background as well
   • In the following example, green represents gray matter, yellow represents white matter, and brown represents the cerebrospinal fluid (CSF):
   • 
   • Void Id: 0
     • Value that specifies nothing in the label map
6. Specify the segmentation parameters
   • The goal segmentation buttons provide example parameters depending on whether the shapes of the expected segmentations are jagged, smooth or intermediate
   • In this example, we will use custom parameters
   • Erosion Radius: 0
   • Hole Fill Iterations: 2
   • False Positive Ratio: 1.00
   • Probability Smoothing Standard Deviation: 1.00
   • Draft Mode: Off
   • Reclassify Object Mask: On
   • Reclassify Not Object Mask: On
7. Run the segmentation
   • Click the "Segment" button
   • Select "Volume" as the label map to view the results
   • 
   • 
   • To view the label outlines, select "Show label volume outlines"
   •
