The Mechanism

How REMS® works.

REMS® is the technology that finally asks the engineer's question. Not how much material is there. Will it hold. Here is how it does it.

REMS® sends a sound wave into your bone and listens to what comes back. The echo carries information about your specific bone tissue: its density and its internal structure. That acoustic signature is unique to your bone. No hospital. No radiation. No referral required.

Step by step

Five steps, one session.

From the probe on your skin to a structural read of your bone, here is what happens and why each step matters.

01

The Scan

A probe is placed at your lumbar spine and proximal femur, the same two sites used in standard bone density assessment. A sound wave enters your bone. The returning echo is captured.

02

The Filtering

REMS® automatically discards everything that is not structural bone. Only the signal from load-bearing bone is kept.

Why this mattersNot everything in a scan's path is structural bone. Calcifications, deposits, and the degenerative changes that accumulate with age can all muddy a reading. To assess the bone that actually bears load, the rest has to be set aside.

What REMS® addsREMS® isolates the signal from load-bearing bone and discards the rest, automatically, in real time, in a portable setting. What remains is a clean reading of your actual structural bone.

03

The Analysis

Your bone's specific acoustic signature is extracted and analyzed.

Why this mattersDensity tells you how much mineral is present. It does not describe how that mineral and collagen are organized, the internal architecture that determines whether bone holds under force. REMS® reads that architecture directly, from the acoustic pattern your bone produces.

What REMS® addsTwo bones with identical density can differ in structural quality, and that difference shows up in the acoustic signature. REMS® reads it.

04

The Comparison

Your signature is compared against a reference database of 10,000+ real bone specimens matched to your age group, sex, and body size, including both structurally healthy bone and bone that has fractured under low force.

Why this mattersA ranking tells you how your bone compares to a reference population. Useful, but it is an average, not your bone. To know whether your structure resembles bone that holds, you need a comparison built from real bone with known outcomes.

What REMS® addsFrom that comparison comes the Fragility Score: a structural window into fracture risk, drawn from your own bone rather than estimated from population averages.

05

Your Results

Bone mineral density, T-score and Z-score. Fragility Score, a structural fracture-risk indicator. Body composition: fat mass and BMR. All from one session, reviewed with you the same day.

Why this mattersMeaningful change in bone takes time, and to catch it early your assessment has to be precise enough to separate real change from measurement noise. REMS® precision error is under half a percent at the lumbar spine. Change at six months is detectable. Because it uses no radiation, REMS® can be repeated as often as the clinical picture warrants, six months, not years.

What REMS® addsRescan at six months and you see what your protocol actually produced. Not an estimate. A measurement.
