Spine Statistics (spine/spinestats)

Clinical spine measurements computed from POI objects and NII segmentations.

Modules

Module	Description
distances.py	Distances between anatomical landmarks (IVD height, canal diameter, …)
angles.py	Cobb angle and other spine curvature measurements
ivd_pois.py	Intervertebral disc (IVD) Point of Interest computation
body_quadrants.py	Subdivides vertebra bodies into anatomical quadrants
make_endplate.py	Generates superior/inferior endplate surfaces from segmentations

Key functions

Function	Module	Description
compute_cobb_angle(poi)	angles.py	Cobb angle between vertebra pairs from POI coordinates
compute_ivd_height(poi)	distances.py	Inter-vertebral disc height at a given level
calc_ivd_pois(vert_nii, subreg_nii)	ivd_pois.py	Compute IVD POIs from vertebra + subregion segmentations
make_endplate(nii, poi, ...)	make_endplate.py	Fit an endplate surface to a vertebra body

Coordinate convention

All measurement functions consume POI objects (voxel or world space) produced by calc_centroids or calc_poi_from_subreg_vert from the core module.
