Stephanix Selenia Dimensions 6000 3D
Stephanix · Model Selenia Dimensions 6000 3D
FAST technology automatically allows the paddle to be tilted towards the nipple during the compression phase to better distribute the force by increasing the contact surface, immobilizing the breast more evenly. With C-View you benefit from a reconstructed 2D image from tomosynthesis data. It is much more than a simple 2D image, machine learning enriches this 2D image with important details while reducing the impact of superpositions and limits of the classic 2D image.

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.
Image quality / detector-calibration fault
HighSymptoms: Fixed-pattern artefacts, non-uniformity, dead lines, failed flat-field calibration, failed ACR / MQSA phantom.
Root cause: Detector degradation, a calibration issue, or a bad pixel map.
Compression / paddle fault
MediumSymptoms: Compression will not apply or hold the set force, paddle not recognised, force readout wrong.
Root cause: Compression drive / motor, the force sensor, or a paddle-detect fault.
Gantry / C-arm rotation or AWS-communication fault
MediumSymptoms: C-arm will not rotate / lock, angle readout wrong, or the acquisition workstation loses the gantry.
Root cause: Rotation drive / brake / encoder, or the gantry-to-AWS link.
X-ray generator / tube fault
HighSymptoms: Exposure inhibited, kV / mAs error, tube-overload interlock, AEC fault.
Root cause: Generator, the mammo tube / filters, or the AEC.
Acquisition workstation / PACS fault
MediumSymptoms: Images will not display, mark-up or send to PACS / review workstation.
Root cause: AWS PC or the DICOM configuration.

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: Image quality or calibration fault
- Run the detector flat-field / gain calibration and the bad-pixel map.
- Perform the daily / weekly QC (ACR phantom, SNR / CNR) and compare to the control chart.
- Inspect for physical detector damage.
- Keep the unit down and escalate anything affecting dose or diagnostic image quality (MQSA).
- Re-run the phantom QC after any correction.
Symptom: Compression or gantry fault
- Test compression apply / release and the force readout against a known weight.
- Check the paddle is recognised and the detect contacts are clean.
- Test C-arm rotation and lock at several angles.
- Confirm the AWS sees the gantry.
- Escalate a drive / encoder / force-sensor fault to the OEM.
