Khan Ceph Trainer

Khan Ceph Trainer helps you learn and sharpen cephalometric landmark identification. Load a lateral cephalogram, place the landmarks, and get scored in millimeters against an answer key: landmark by landmark. After each round you see your mean error, how many points landed within 2 mm, a color-coded breakdown (green ≤2 mm, amber ≤4 mm, red >4 mm), and an overlay drawing the line from each of your placements to the reference point, so you can see exactly where you drifted. Author a case: load your own cephalogram, optionally set a scale by clicking a known distance, and mark the 16 landmarks once to create the answer key. Practice: place the landmarks blind, submit, and review your accuracy. Retry as often as you like every attempt is saved. Share: export a case to a single file and send it to students or colleagues, who import it and practice. No account, no server. Everything runs locally in your browser. Khan Ceph Trainer requests no permissions, makes no network requests, and keeps your cases and history on your device only. This is an education and self-study tool. It does not diagnose, recommend treatment, or replace clinical judgment.
