Device Classification

Product Code SAO Radiology Software For Opportunistic Evaluation Of Low Bone Mineral Density
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 892.1171
Definition This Device Is Software Which Opportunistically Assesses Radiological Images To Estimate Bone Mineral Density (bmd) Intended To Assist In A Healthcare Professional's Decision To Evaluate Patients For Possible Low Bmd Within A Bone Health Screening Program. The Software Employs An Algorithm That Estimates Bmd Using Eligible Radiological Image Data Obtained For Other Clinical Purposes.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Radiology devices follow this clearance model.
