NASA is using Echolight's proprietary REMS (Radiofrequency Echographic Multi Spectrometry) technology to monitor bone changes in a human bedrest study and to assess the effects of unloading on bone mass given the paramount importance of Bone Health in space too.
Through a simple ultrasound scan of axial anatomical sites such as the spine and femur, the REMS innovative technology measures bone density and microarchitecture without using the radiation of traditional x-ray scans. This radiation-free technology allows scientists to perform repeated scans for monitoring bone health over time. In addition, the ability to automatically exclude artifacts commonly present with other densitometry procedures yields a highly reliable diagnostic assessment.
