Spine screening support for AP/PA radiographs
Upload a frontal radiograph to review vertebral landmarks, Cobb angles, and height morphology from the screening API.
AP / PA
Supported views
JPEG and PNG frontal radiographs.
API v1
Current API
Returns landmarks, measurements, warnings, and review status.
How it works
From upload to results
The site shows model measurements for research screening support. It does not provide a diagnosis.
Choose an AP or PA JPEG or PNG, or load an example image.
The same image is used as the background for the result overlay.
The API returns a center and four corner points for each detected vertebra, ordered from top to bottom.
The detector score indicates measurement reliability, not fracture probability.
The site draws the corner points, Cobb lines, and angles over the original image.
Cobb angles are geometric measurements, not fracture probabilities.
Each vertebra shows mean height, change from its neighbor reference, and left/right asymmetry.
Negative height change may be flagged. The value is not calculated when the neighbor reference is unreliable.
Morphology signals and detector reliability are shown separately.
Low-reliability signals remain visible. AP/PA asymmetry may come from spinal curvature, rotation, or landmark error.
