Manual point-click hindfoot alignment measurement
Upload a hindfoot alignment radiograph and a posterior standing clinical photo. Click four landmarks on each image to calculate angles, compare results, and export training-ready labels.
Point-click workflow
Radiograph HAA
- Click proximal tibial axis point.
- Click distal tibial axis point.
- Click tibial axis / joint-line intersection point.
- Click most inferior calcaneus point.
Clinical photo angle
- Click proximal leg/Achilles midline point.
- Click distal leg/Achilles midline point.
- Click heel-axis proximal point near posterior ankle.
- Click inferior/posterior heel center.
Dataset-first design: Every finished measurement can export JSON labels with landmark coordinates, image dimensions, angles, and metadata for future machine-learning training.
