Portable DEXA & Bone Density Machines: The Buyer's Guide
What 'portable' really means in bone densitometry, which models exist, and who should buy one instead of booking scans.
There is no portable whole-body DEXA machine. What's sold as "portable" is peripheral DXA (pDXA) — X-ray scanners for the forearm or heel, from about $15,000 — and quantitative ultrasound (QUS) heel scanners from about $8,000. Both are screening tools: they estimate fracture risk and flag who needs a central DEXA scan, but they can't diagnose osteoporosis at the hip and spine or measure body composition. If a vendor implies otherwise, that's your cue to shop elsewhere.
Portable vs Central DEXA
Central DEXA machines scan the hip and spine — the sites where osteoporosis is diagnosed and treatment monitored per ISCD official positions — plus whole-body composition. Portable units measure peripheral sites only:
- pDXA can: measure bone density at the forearm or heel, screen large populations cheaply, and satisfy some pharmacy/wellness screening programs.
- pDXA can't: diagnose osteoporosis at the hip/spine, monitor treatment response, or run body composition. A screening result that's low still gets referred to a central DEXA.
- QUS (heel ultrasound) can: estimate fracture risk with zero radiation and no state X-ray registration — the lightest-touch screening option for events and pharmacies.
- QUS can't: measure bone mineral density at all; it measures how sound travels through bone. It is strictly a pre-screen.
Who Actually Buys Portable Units
- Mobile screening businesses running osteoporosis-risk events at senior centers, employers, and health fairs — volume screening with referral revenue downstream.
- Pharmacies and wellness chains adding a bone-health check to existing service menus.
- Research groups doing field studies where a table unit can't travel.
- Integrative and physician clinics that want an in-office screen before referring out for central DEXA.
Models & Prices
| Model | Technology | Site | Indicative Price | FDA Status |
|---|---|---|---|---|
| GE Achilles EXPII | QUS (ultrasound) | Heel | $8,000–$20,000 | 510(k) cleared |
| Osteosys EXA-3000 | pDXA (X-ray) | Forearm | $15,000–$25,000 | 510(k) cleared |
| Furuno CM-300 | QUS (ultrasound) | Heel | $10,000–$18,000 | 510(k) cleared |
| Norland pDEXA class | pDXA (X-ray) | Forearm/heel | $15,000–$30,000 | 510(k) cleared |
Indicative ranges, last verified July 2026. Confirm clearance status for the specific model/generation on the FDA 510(k) database before purchase — used imports are where surprises live.
Note that pDXA units are X-ray devices: state radiation registration and operator rules apply just as they do for central machines. QUS units, being ultrasound, avoid the radiation-program overhead entirely — a real operating-cost difference for mobile businesses.
For Home Users: The Honest Math
If you landed here wanting to check your own bone density or body composition at home, here's the arithmetic: the cheapest screening device costs about $8,000 and still won't diagnose anything, while a professional DEXA scan costs $100–$250, takes 10 minutes, measures the sites that actually matter, and requires nothing from you but an appointment. Even scanning four times a year, you'd need over a decade of scans to spend what the least capable machine costs — before service, registration, and the fact that it can't do what the scan does.
A professional DEXA scan costs $100–$250 — a machine starts at $15,000. Most partner clinics scan from $99, no referral needed.

Is there a portable DEXA machine?
There is no portable whole-body DEXA machine — full body composition and central bone density scanning require a table-based central unit. What exists is peripheral DXA (pDXA), which scans the forearm or heel, and quantitative ultrasound (QUS) heel scanners. Both are portable screening tools, not replacements for a central DEXA scan.
Can I do a DEXA scan at home?
Not practically. DEXA machines are state-regulated X-ray devices requiring registration and certified operation, and even the smallest peripheral units cost $8,000–$30,000. A professional DEXA scan costs $100–$250 and takes about 10 minutes — for personal tracking, booking scans is dramatically cheaper than owning any device.
How accurate are heel ultrasound scanners?
Quantitative ultrasound (QUS) heel scanners are validated screening tools — they estimate fracture risk and identify people who should get a central DEXA — but they do not measure bone mineral density directly and can't be used to diagnose osteoporosis or monitor treatment under ISCD positions. Treat QUS results as a screen, not a diagnosis.
How much is a portable bone density machine?
QUS heel scanners run roughly $8,000–$20,000 new. Peripheral DXA units (forearm/heel X-ray) run about $15,000–$30,000. Used units of both types surface for less, but verify FDA clearance, calibration history, and state registration transferability before buying.
