MAGNETOM Symphony 1.5T - Clinical Application Expect more patient throughput: New clinical applications to boost referrals. And revenue. With a complete range of clinical applications not available anywhere else, MAGNETOM Symphony with Power-class gives users the ability to serve all kinds of patients, and fulfill any requirements from referring physicians. The comfort of free-breathing 2D PACE MRCP without respiratory belt or cushion (GRAPPA 2, matrix 384, TA 3:32 min). With Inline Technology even advanced applications like fMRI go easy and intuitively. "MAGNETOM Symphony's complete range of applications allows us to serve all patients and fulfill all requirements of our referring physicians. We can now offer the best service for our customers: high comfort, fast scans and excellent image quality." Clinica Antofagasta, Antofagasta, Chile Integrated Panoramic ArrayTM: The power of unmatched performance. Only Siemens offers Integrated Panoramic ArrayTM (IPA) for even faster and more comfortable MRI exams. IPA allows flexible combinations of up to four different coils, so users can expand the anatomic range of coverage without coil or patient repositioning. This can save up to five minutes per procedure or patient. In addition, MAGNETOM Symphony with Power-class comes with lightweight coils that are unmatched for patient comfort. Faster exams, faster throughput, greater patient comfort. Now that’s powerful. MAGNETOM Symphony 1.5T - Patient Benefits More relaxing exams Patients enjoy the open design and the comfort of light-weight coils. IPA coils can be flexibly combined to minimize patient repositioning. Additionally, ease and speed go together: MAGNETOM Symphony enables feet-first access for a large variety of exams. For tremendously increased patient comfort. Short exam times iPAT (integrated Parallel Acquisition Technique), with PAT factors up to 4, minimizes scan time up to 75% and permits short breathhold times. And even more 2D PACE, another Siemens´ exclusive technique for multi-breathhold or free-breathing exams, significantly contributes to patient relaxation. Using IPA, multiple exams can be performed in a single set-up: patients will value the shorter exam time. Starting examinations pleasantly, the patient table lowers down to 45 cm. Convenient for all, but especially important for children, elderly and obese patients.
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.
