The first spinal cord segmentation tool that SCT offers is called
sct_propseg, and it works as follows:
- 1. Centerline detection
sct_propsegstarts by using a machine learning-based method (OptiC) to automatically detect the approximate center of the spinal cord.
(The centerline detection step is also provided in a standalone script called
- 2. Mesh propagation
Next, a coarse 3D mesh is created by propagating along the spinal cord (PropSeg).
- 3. Surface refinement
Finally, the surface of the mesh is refined using small adjustments.
