Bone health analysis software developed by researchers at Johns Hopkins University Applied Physics Laboratory in Laurel, Md., has received FDA 510K clearance that will allow it to be incorporated into a bone densitometer made by Hologic Inc. of Bedford, Md. The approval allows Hologic to market the device, which uses the laboratory’s Hip Structure Analysis method to calculate bone strength from dual-energy x-ray scans. The company has been granted exclusive worldwide rights to the laboratory’s technology.
