Radiofrequency echographic multi-spectrometry is a noninvasive technique for estimating bone mineral density, or BMD, a measure of mineral concentrations in bones that indicate bone strength.
Position the human patient in a supine position.
Apply ultrasound gel to the femoral neck to enhance signal clarity.
The femoral neck is a region of the femur, bones that span from the hip to the knees, and is particularly susceptible to fractures when BMD is low.
Place the ultrasound probe parallel to the femoral head-neck axis to assess BMD at the fracture-prone site.
Adjust the scan depth to position the target region within the beam's focal zone, ensuring optimal resolution.
The probe emits high-frequency ultrasound waves through the bone, which reflect at a speed that increases with higher BMD.
The probe captures these reflected waves, generating a spectrum that provides data for quantifying BMD.
