Who could benefit from this research

Could help

Children whose bone age assessment is needed as part of routine pediatric care.

Less likely to help

Children who do not require bone age assessment or whose X-ray data cannot be used by the AI system.

What this research studies

This project will develop an AI system that reads hand and wrist X-rays to estimate bone age in children, aiming to reduce variability between doctors and improve accuracy for all racial groups. It builds on existing atlas-based methods but uses machine learning to learn from diverse data. The work is designed to be used in pediatrics and pediatric endocrinology to support diagnosis, treatment planning, and prognosis.

Why it matters

Potential benefit: If successful, the tool could provide more consistent bone age estimates across different populations and reduce misinterpretation due to atlas biases.

How similar studies have gone: Previous atlas-based methods have shown promise, and AI-enhanced approaches aim to improve consistency and accuracy across diverse groups.
