Planmed Nuance
Planmed · Model Nuance
• 85 µm pixel size amorphous selenium (a-Se) direct-conversion detector provides high dose efficiency and ultimate image quality • Two detector sizes - 17x24 cm (Planmed Nuance) and 24x30 cm (Planmed Nuance Excel) – fit for all you need in digital mammography • Tungsten tube, Ag/Rh filters and ingenious Flex-AEC automated exposure control provide you with the lowest possible radiation dose for breasts of all sizes and compositions • Dedicated image processing
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
X-ray tube overheating / filament failure
HighSymptoms: Tube won't fire, heat-capacity alarm.
Root cause: Filament wear, cooling failure.
Cooling system fault
HighSymptoms: Tube temp alarm, duty-cycle limited.
Root cause: Pump/radiator or coolant loss.
Generator / high-voltage fault
HighSymptoms: Exposure fails, kV/mA out of range error.
Root cause: HV tank or generator board fault.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or RAID degradation.

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: X-ray tube overheating / filament failure
- Confirm the presentation - typically tube won't fire, heat-capacity alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: filament wear, cooling failure.
- 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 x-ray tube insert 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.
Symptom: Detector calibration drift
- Confirm the presentation - typically image noise, artifacts, low SNR - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: flat-panel / sensor aging.
- 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 flat-panel detector 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.
