Vertebral segmentation & alignment

Sagittal alignment, measured automatically.

SpineContour is a research application that segments each vertebra from T12 to S1 on a lateral spine radiograph and derives the sagittal parameters used in spine research — lumbar lordosis, pelvic incidence, pelvic tilt, sacral slope, and PI–LL mismatch — in seconds, entirely on your workstation.

01 · What it does

Per-vertebra segmentation

Automatic contours for T12–S1 with a per-study segmentation confidence score. Review and adjust the overlays directly on the film.

Sagittal parameters

Lumbar lordosis, pelvic incidence, pelvic tilt, sacral slope and PI–LL mismatch — plus disc heights and spondylolisthesis in millimetres, exportable as CSV or a PDF report.

Local by design

Nothing is uploaded — files are read from disk on this workstation. De-identified research images never leave your machine.

03 · Segmentation accuracy

Validated against expert annotation.

Dice coefficient vs. expert annotation
Mean endplate error millimetres
Parameter agreement vs. manual measurement (ICC)

Validation results forthcoming — figures will be published here alongside the methods paper.

04 · Research use

Research use only

Not for diagnostic or clinical use.

SpineContour is an investigational research tool. Its measurements, segmentations, and derived metrics have not been cleared or approved by any regulatory body. All output requires independent verification by a qualified reviewer.
