GE HealthCare Lunar Achilles InSight
GE HealthCare · Model Lunar Achilles InSight
Automated and self-contained - The standard system is an automated and self-contained unit with an internal printer. The on-board memory stores up to 300 patient results, which you can review or print at your convenience. Printouts are easily attached to permanent patient records. DICOM - DICOM (Digital Imaging and Communications in Medicine) is a standard for transferring digital media images and associated information between devices. The DICOM standard specifies information that vendors must supply about their product, when the product claims to be DICOM standard compliant. Lunar’s DICOM Conformance Statement defines what DICOM protocols our product includes and the details it uses in communication with an existing Picture Archiving Communications System (PACS) or Radiology Information Server (RIS).
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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
QC / calibration phantom out of tolerance
HighSymptoms: Daily spine / block phantom BMD trends out of control limits, or calibration fails.
Root cause: X-ray source output drift, detector degradation, or a calibration-drum / reference fault.
C-arm / table scanning-drive fault
MediumSymptoms: The scanning arm or table will not move smoothly, position error, scan aborts, image geometry wrong.
Root cause: Drive motor, belt, or an encoder / limit-sensor fault.
X-ray generation fault
MediumSymptoms: Exposure inhibited, kV error, no counts / very noisy scan.
Root cause: X-ray tube / HV supply, or the filter-wheel / calibration-drum.
Detector fault
MediumSymptoms: Missing scan lines, non-uniform image, detector-error message.
Root cause: Detector element / electronics degradation.
Workstation / software fault
LowSymptoms: Analysis software hangs, scans will not archive or transfer.
Root cause: Workstation PC or software fault.

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 starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: QC phantom out of tolerance
- Repeat the daily phantom scan and apply the shift / drift rules.
- Confirm the phantom is correct and correctly positioned.
- Run the system calibration.
- Review the source / detector trend.
- Escalate a confirmed source or detector drift to the OEM; do not scan patients until QC is back in control.
Symptom: Scanning-drive / geometry fault
- Note the position / geometry error.
- Check for a mechanical obstruction on the arm / table.
- Run the drive self-test / calibration.
- Inspect the drive belt and encoder.
- Replace the drive component or refer as isolated.
