Siemens MAGNETOM Symphony 1.5T
Siemens Healthineers · Model MAGNETOM Symphony 1.5T
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Helium / cryogen pressure fault
HighSymptoms: Cold-head fault, quench alarm.
Root cause: Cold-head compressor wear or helium loss.
Gradient coil overheating
HighSymptoms: Sequence abort, thermal alarm.
Root cause: Cooling loop restriction or coil wear.
RF coil element failure
MediumSymptoms: Signal dropout, noise-band image artifact.
Root cause: Coil element or cable damage.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or RAID degradation.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Helium / cryogen pressure fault
- Confirm the presentation - typically cold-head fault, quench alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: cold-head compressor wear or helium loss.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the rF receive coil per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
