Brain Cancer: WhiteStripe Normalization

This algorithm normalizes conventional brain MRI scans [1] by detecting a latent subdistribution of normal tissue and linearly scaling the histogram of images.

REQUIREMENTS:

  • Bias-corrected (N3 or N4) T1-weighted or T2-weighted images, ideally either skull-stripped or rigidly aligned to MNI space.

USAGE:

  1. Launch the WhiteStripe UI using the 'Applications -> WhiteStripe Normalization' menu option.
  2. Specify the Input and Output files and different parameters (defaults are populated).
  3. Click on 'Run WhiteStripe" and the results can be seen in a slice format using "Toggle Mask/Image" checkbox.
  4. Use 'Level Display' when needed.
  • This application is also available as with a stand-alone CLI for data analysts to build pipelines around, using the following example command:
    WhiteStripe.exe -i C:/inputImage.nii.gz -o C:/outputImage.nii.gz
    

NOTE: WhiteStripe uses the KernelFit library from Lentner (https://github.com/glentner/KernelFit).
