Single channel automatic segmentation of t1w-MRI brain scans into the major tissue classes (gray matter, white matter, csf). The task can only be applied to t1w brain scan showing parts of the skull and neck. The pipeline consist of the following steps:

Description

-- Data Assumption
-- description of pipeline with citations to algorithms used

Anatomical Tree

-- Define Anatomical Tree used in mrml file - first list the complete name and then the abbreviating used in the mrml file

  • root
    • background (BG)
      • air (AIR)

Atlas

- how did you construct the atlas ?
-- what did you do for skull stripping or any other preprocessing
-- What did you do for group registration
-- how did you generate the segmentations
-- how many set of images did you use
-- where did you get the data from
-- example images of atlas such as

Acknowledgment

The construction of the pipeline was supported by funding from NIH NCRR 2P41RR013218 Supplement.
