Module Description

This module offer a simple and robust brain tissue segmentation focused on white matter, gray matter and CSF brain tissues. The method applied here is based on naive Bayesian segmentation, which presents good results with high quality T1 weighted MRI images.

NOTE: This module can be used alone (only apply the naive Bayesian segmentation method on the input data), but the Brain Structures Segmenter module already use it internally, which control a image processing pipeline for a better brain tissue segmentation result.

Use Cases

  • Use Case 1: Separate White Matter, Gray Matter and CSF brain tissues from a strucutral MRI image.
    • There are some image processing strategies that may need a specific brain tissue mask and this module could facilitate this task. For instance, a Multiple Sclerosis lesion detection algorithm may need a White Matter mask in order to define a localized brain region where the lesion are more probable to appear.

  • White matter, gray matter and CSF tissues segmented from the previous MRI image

  • A white matter mask 3D reconstruction

  • A gray matter mask 3D reconstruction
