text: Radiofrequency Echographic Multi Spectrometry (REMS) is a non-ionizing technology for osteoporosis diagnosis and for fracture risk assessment. REMS processes the raw, unfiltered ultrasound signals acquired during an echographic scan of the axial sites, femur and spine. The analysis is performed in the frequency domain.  Bone mineral density (BMD) is estimated by comparing the results against reference models.
  The accuracy has been tested by comparing it against to DXA technology.
