- •
A novel combined SCP and geometric (CSCPG) 3D spine reconstruction and deformity quantification methods have been proposed and validated.
- •
CSCPG model is obtained by deforming the SCP reconstructed model using the vertebral orientation features.
- •
The limited number of landmarks, low cost calibration apparatus and a simple generic model make the entire procedure very economical.
- •
A semi-automatic method for evaluating spinal deformities with minimum human intervention is presented and validated.
- •
These techniques are simple, fast and significantly reduce the observer variability.
