Siemens MAGNETOM C 0.35T
Siemens Healthineers · Model MAGNETOM C 0.35T
Expect superb image quality from the true multi channel RF system with the best SNR at 0.35 T and the largest anatomical coverage in mid-field. MAGNETOM C! offers exceptional gradients for rapid acquisition and highly differentiated image details. Iso-center imaging assures excellent image quality for all anatomical areas. Advanced techniques such as comprehensive cardiac imaging and the unique syngo REVEAL revolutionize mid-field capabilities. syngo REVEAL for body diffusion increases metastasis conspicuity and permits virtually instant yes/no diagnostic decisions. syngo GRAPPA parallel acquisition technique for higher resolution, larger coverage and faster scans, significantly speeds workflow. Referring physicians will notice and appreciate the improved service. From now on, with MAGNETOM C! high-field diagnostic confidence at mid-field can be your standard. Broad range of sequences and techniques for all clinical applications. Included in the standard package Patient comfort at its best More space means less anxiety. A unique C-shaped magnet for easy side loading and a friendly, compact design cooperate to create an open and free atmosphere. The smallest pole diameter – 137 cm (54“) ensures optimal patient comfort. For up to 65% of all exams, the patient’s head remains outside the magnet, giving a feeling of spaciousness and relaxing claustrophobic tensions. Easy 270° accessibility, the patients always feel close to assistance. The patients will appreciate the quick and comfortable examinations. Posterior coil parts remain on table for more than 95 % of the exams. Obese patients appreciate the comfortable side loading. For these patients, MAGNETOM C! comes with unique extra large body and knee coils. These advantages, combined with the open, patient-friendly design, attract more patients, who will recommend user site.
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.
