This is the MICCAI-challenge-like datastructure of **VerSe19**, that is the *image series based*.
Here, four files can be found per image series:
(1) verse000.nii.gz - CT image series
(2) verse000_seg.nii.gz - segmentation mask
(3) verse000_ctd.json - centroid coordinates in 1mm isotropic ASL-space
(4) verse000_snapshot.png - Preview reformations of the annotated CT data.
Centroid coordinates (.json file) are given in 1mm isotropic resolution with coordinate origin at 'X'= anterior, 'Y'= superior, and 'Z'= left (ASL).
'label' corresponds to the vertebral label:
1-7: cervical spine: C1-C7
8-19: thoracic spine: T1-T12
20-25: lumbar spine: L1-L6
26,17: sacrum, cocygis - not labeled in this dataset
28: additional 13th thoracic vertebra, T13, not present in this dataset.
