Image and context together
We plan to bring the hand–wrist radiograph, acquisition date and information needed for assessment into one workspace.

RAI BoneAge
In development to bring bone age assessment from hand and wrist radiographs together with clinical context and clinician review.
Skeletal maturity · Clinical assessment
A clearer perspective on growth.
RAI BoneAge is our bone age assessment product designed for radiology and paediatric endocrinology teams. We aim to bring the image, assessment method and report draft into one workflow that supports clinical review.
Beyond a number: the context of assessment.
Bone age describes skeletal maturity. It is considered alongside chronological age; growth history and other clinical findings inform its interpretation. Our design gives attention to how a result is reviewed, as well as how it is presented. [1]
Planned tools for clinical review
A clear result layout
We aim to show bone age in years and months alongside chronological age, the assessment method and its limitations.
Image suitability first
Quality and scope checks are planned at the start of the workflow, with an explained inability to assess unsuitable or unsupported images.
A report completed by the clinician
An editable report draft, clinician review and traceable changes. The final clinical decision remains with the clinician.
A connected path from image to assessment.
Select the image
DICOM upload in Pro and study selection through PACS/VNA in Enterprise are planned. Supported images and ages will be clearly stated.
Review the assessment
View the result, method and limitations alongside the image. Evaluate their fit with the clinical context.
Complete the report
Review and edit the draft. Institutional image and report transfer will follow integration validation.
What does bone age AI research show?
These peer-reviewed studies describe the scientific background. They evaluate other developers’ systems, not the clinical validation or performance of RAI BoneAge.
Comparative evidence from Türkiye
In 292 children, VUNO and BoneXpert agreed closely with manual assessment; neither was significantly superior. Selected cohort; known disorders excluded.

In 200 radiographs, software assistance shortened two reviewers’ reading times. A retrospective study of that specific system.

Responsible AI starts with defined limits.
Our plan for RAI BoneAge makes the analysis engine version, assessment method and supported scope visible. Clinical validation, local conditions of use and institutional integration will be assessed separately.
Questions, answered
Can I use RAI BoneAge today?
The product information page is available; the calculation service and clinical use are not yet open. Supported scope and access details will be shared when ready.
Which assessment method will be used?
Greulich–Pyle and Tanner–Whitehouse methods inform our product evaluation. The offered method will depend on the selected analysis engine and validation results, and will be stated in each report.
Are height prediction and bone health analysis included?
The initial scope is bone age assessment and a clinician-reviewed report. Adult height prediction and a bone health index are being considered for later phases with separate validation.
Do these studies prove RAI BoneAge’s accuracy?
No. The publications examine the field and other systems. RAI BoneAge needs its own clinical performance evaluation; no RAI accuracy rate or regulatory clearance is claimed here.
