MRI-Safe
AADCO MEDICAL, INC. · Model OSP-511LNF
MRI SAFE LED 44000 LUX PROCEDURE LAMP W/ REMOTE 100 TO 240 VAC POWER.
Intended use: A structure intended to be permanently-fixed to the ceiling and/or wall to support/stow a medical device(s) [e.g., light, monitor, surgical instruments] or stow/provide medical supplies. It is designed with specific characteristics as requested by a healthcare professional to meet the requirements of a specific facility. It may incorporate a pole, rack, shelves, electricity supply sockets, gas outlets, and/or enable dynamic positioning (e.g., with dynamic arms, sliding bracket); the device(s) to be mounted is not included.
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.
RF coil fault / poor SNR
HighSymptoms: Low signal-to-noise, shading, or a dead region in images; coil not detected or fails the coil check.
Root cause: Damaged RF coil element, a coil-cable / connector fault, or a preamp fault.
Gradient fault / image distortion
HighSymptoms: Geometric distortion, gradient-amplifier faults, acoustic change, over-temperature trips.
Root cause: Gradient-amplifier fault, gradient-coil cooling problem, or a gradient-coil fault.
Cryogen / cold-head / compressor fault
HighSymptoms: Rising helium boil-off, cold-head noise or stall, He level dropping, compressor alarms.
Root cause: Cold-head at end of life, a helium-compressor fault, or a chilled-water problem.
Chilled water / cooling fault
MediumSymptoms: System-cooling alarms, gradient or RF over-temperature, scans aborting.
Root cause: Facility chilled-water supply, the heat exchanger, or internal pumps.
Patient table / positioning fault
MediumSymptoms: Table will not dock, drive or index; landmarking errors.
Root cause: Table drive, docking sensor, or encoder fault.
Reconstruction / host / network fault
MediumSymptoms: Recon errors, host hangs, images will not reach PACS.
Root cause: Recon or host computer fault, or the network / storage.

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: Poor SNR or a dead region with one coil
- Swap in a known-good coil of the same type and repeat the scan.
- Run the coil-check / coil-QA tool.
- Inspect the coil housing and cable for damage; reseat the connector.
- Scan the ACR / QA phantom and compare SNR to baseline.
- Quarantine and exchange the faulty coil.
Symptom: Rising helium boil-off or cold-head noise
- Log the helium level and boil-off trend daily.
- Check the cold-head sound and the compressor pressures against spec.
- Confirm the chilled-water supply temperature and flow.
- Schedule a cold-head / compressor service before the level reaches the OEM action point.
- Never let the magnet approach a quench threshold - escalate urgently.
