GE HealthCare Lunar Prodigy Primo
GE HealthCare · Model Lunar Prodigy Primo
• Proven bone densitometer - The Lunar Prodigy® bone densitometer features direct-digital technology that eliminates the magnification effects of traditional wide-angle fan beam densitometers. With more than 6,000 systems installed worldwide, Prodigy is one of the most trusted fan beam densitometers available. • OneVision - With OneVision you and your referring physicians receive a single, consolidated report that combines the complete risk assessment analysis rather than receiving multiple assessment reports. • Dual-energy Vertebral Assessment-DVA - DVA expands the clinical applications available for the Lunar Prodigy Primo bone densitometer. DVA provides rapid, dual-energy images of the AP and lateral spine, allowing clinicians to visually assess vertebral deformations. • DualFemur - The DualFemur feature automatically measures both left and right femurs in one fast scan, and improves accuracy by identifying the femur with the lowest density. The 30? improvement in precision enhances the ability to monitor response to therapy. • Patient Reports - The Lunar Prodigy Primo patient report displays T-scores and Z-scores along with the fracture risk assessment graph, based on the World Health Organization (WHO) criteria to define osteoporosis, and key diagnostic information. This makes interpretation of results and fracture risk assessment seamless. • Total-body-body composition - Body composition scans with DXA provide precise and accurate data on bone and tissue composition, including bone mineral density (BMD), lean and fat tissue mass, and %fat. They provide both total body data and regional results. • Benefits - Effective use of serial DXA measurements for monitoring changes in BMD requires the minimization of precision error. The Lunar Prodigy® Primo has been demonstrated to have a precision error that easily meets the ISCD standards for all regions. • Technology - The Lunar Prodigy Primo utilizes a direct-digital array detector and narrow-angle fan-beam technology to enhance dose efficiency and achieve excellent precision and patient throughput in spine, femur and total body measurements.
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
Typical Failure Modes

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Recon / system software hang
- Confirm the presentation - typically frozen console, acquisition timeout - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: workstation or storage degradation.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the workstation / GPU per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
