How it works

AI-Driven TW3 Bone Age Assessment

ROIs used in the TW3-RUS method. The TW3 method evaluates the 13 ROIs (i.e., the radius, ulna and short bones of the first, third, and fifth fingers) to determine the maturity levels of individual ROIs.

Afterwards, each level is re-placed by a maturity score, and the total score is calculated. Finally, the total score is convert-ed into a bone age.
