GE Lunar DEXA Machines: Prices, Models & Where to Buy
Prodigy vs iDXA compared — 2026 pricing new and used, the enCORE licensing gotcha, and what ownership really costs.
GE HealthCare's Lunar line is one half of the DEXA duopoly. The Prodigy is the high-volume clinical standard (roughly $60,000–$80,000 new, $12,000–$28,000 used) and the iDXA is the research-grade flagship ($80,000–$100,000+ new, $25,000–$50,000 used), with prices verified July 2026. As with Hologic, the decisive question on any used quote is which enCORE software options are licensed and transferable.
GE Lunar Model Lineup
| Model | Status | Technology | Body Comp | New | Used |
|---|---|---|---|---|---|
| iDXA | Current flagship | Narrow fan-beam, HD detector | Yes + CoreScan (licensed) | $80,000–$100,000+ | $25,000–$50,000 |
| Prodigy | Current | Narrow fan-beam | Yes (licensed) | $60,000–$80,000 | $12,000–$28,000 |
| Prodigy Advance / Pro (older gens) | Discontinued | Narrow fan-beam | Yes (licensed) | — | $8,000–$18,000 |
| Achilles EXPII | Current (screening) | Quantitative ultrasound | No | $12,000–$20,000 | $5,000–$12,000 |
Indicative ranges, last verified July 2026. The Achilles is a heel-ultrasound screener, not a DEXA — see the portable guide.
Prodigy vs iDXA
The Prodigy earns its ubiquity: fast scans, compact footprint, proven reliability, and the deepest used inventory of any DEXA model — which is why it's the default recommendation for clinical bone density and budget-conscious body-comp startups.
The iDXA is what you buy when precision is the product: a higher-resolution detector, visibly better whole-body images, tighter precision for tracking small composition changes, CoreScan visceral-fat quantification, and a 450 lb table. Research groups and premium longevity clinics standardize on it; if your clients are paying for serial scans to track lean-mass changes of a pound or two, the iDXA's precision is marketable.
One platform note that matters for serial data: Hologic and GE results are not interchangeable — bone density and body-comp values differ systematically between platforms. Whichever brand you buy, your clients' historical scans compare cleanly only on the same platform.
enCORE Software Licensing: The Gotcha
GE's enCORE software licenses features individually: total-body composition, CoreScan (visceral fat), advanced hip analysis, and more are options, not standard equipment. On used machines, options must be documented and formally transferred — a used Prodigy "with body comp" that lacks transfer paperwork can cost thousands to re-license. Demand the enCORE option list and written transfer terms before paying.
The full pre-purchase drill — tube life, phantom QC records, license transfers — is in the 9-point inspection checklist.
Service & Ownership Costs
- Service contracts: roughly $6,000–$12,000/year through GE; independent service organizations service Lunar units widely, typically 30–50% below OEM rates.
- Parts: excellent availability for Prodigy and iDXA; older Prodigy generations (Advance/Pro) are ISO-and-salvage territory now.
- Tube life: Lunar tubes are long-lived but model-specific — price any used unit against its tube history, not its cosmetics.
- Brand-independent costs (install, physicist survey, registration) are itemized in the cost guide.

How much does a GE Lunar DEXA machine cost?
New GE Lunar systems run roughly $60,000–$100,000+ (Prodigy at the lower end, iDXA at the top). Used Prodigy units trade at $12,000–$28,000 and used iDXA units at $25,000–$50,000, driven by tube life, detector generation, and which enCORE software options are licensed and transferable.
GE Lunar Prodigy vs iDXA — what's the difference?
The Prodigy is the high-volume clinical standard — narrow fan-beam, fast, compact, and the most common GE unit on the used market. The iDXA is the research-grade flagship: higher-resolution detector, better precision for body composition and visceral fat, larger table capacity, and a higher price. Research and longevity facilities gravitate to iDXA; general clinical use is well served by Prodigy.
Is enCORE software included with a used GE Lunar machine?
Not necessarily — enCORE options (body composition, CoreScan visceral fat, advanced hip analysis) are licensed features, and license transfer on used units must be arranged and documented. A used Prodigy 'with body comp' that lacks transfer paperwork may cost you thousands to re-license. Get the enCORE option list and transfer terms in writing before you pay.
