MRIequip Non-Magnetic Multi-Level MRI Stretcher
MRIequip · Model Non-Magnetic Multi-Level MRI Stretcher
The “Standard” and the lightest lift-in cot in the industry (built of aluminum). Ferno’s Model 30 Multi-Level, Lift-in Cot served as the industry standard for many years and is still used by many ambulance companies and medical facilities. The Ferno Model 30 cot adjusts to six height levels, enabling patient transfer from most nursing home beds or hospital treatment tables. To operate the height adjustment mechanism, the EMTs must assume the patients weight prior to raising or lowering the cot-bed frame. Because the Model 30 must be lifted to be loaded into the vehicle, it can be used with ambulances that have various floor heights. The Model 30 cot will work well in station wagons, vans or modular ambulances. The telescoping head-end main frame section allows the Model 30 cot to be shortened for maneuverability around tight corners and spaces. The Model 30-NM is the Non-Magnetic version for medical treatment areas where the cot must be non-magnetized.
Key tips
- ·Casters and the wheel-lock brake take the most day-to-day wear - check both every PM, not just on complaint.
- ·A cracked weld or loose frame joint is a safety-critical finding - pull the unit from service until it's repaired.
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.
- ·Caster / wheel and brake function check
- ·Frame, weld, and mounting-hardware inspection
- ·Upholstery / surface condition check
- ·Annual full PM
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.
