Bone Age Finder
From a hand X-ray to a growth assessment, with the doctor in control.
Bone Age Finder uses AI to estimate a child's bone age from a hand X-ray by comparing it against a reference atlas. The doctor reviews the estimate and either confirms it or adjusts it. The platform then compares bone age with chronological age and estimates the growth remaining.

What it provides
AI bone age estimate
Based on the patient's image and the atlas
Doctor confirmation or correction
Before anything goes into the report
Difference from chronological age
Shown in months
Bone age SDS
The difference expressed in standard deviations against sex-specific reference values. Read as advanced or delayed, and flagged at ±2 SD
Growth remaining
Bayley-Pinneau method: percentage of adult height attained and growth left. With the current height entered, it also gives a predicted adult height and the remaining height in cm
Pattern classification
Delayed, average or accelerated maturation
Built for review and control
- The AI proposes and the doctor decides. Any estimate can be changed if the doctor disagrees
- Chronological age is calculated from the birthdate, or entered manually
- Growth-remaining results appear only when the method is valid for the case, and are withheld when bone age and chronological age differ by more than 2 years
- Clinical uses include endocrinology, growth disorders, puberty assessment and scoliosis or limb-length timing
