Figure 1
X-ray phase contrast tomography images of the lumbar region of the spinal cord. Example of the MN 3D segmentation process. (a) A ROI was selected in the ventral horn of the spinal cord where the MNs are anatomically concentrated. (b) An intensity threshold segmentation was performed to isolate MNs. (c) Superimposed image of (a) and (b) to show the output of the segmentation process. |
