What This Guide Helps With
Troubleshooting MAGNETOM Skyra patient table movement, docking, positioning, or drive-related faults before escalation.
Step-by-Step Troubleshooting
Ensure Patient Safety First
If a patient is on the table and movement is abnormal, delayed, noisy, or unavailable, stop table operation immediately.
Communicate with MRI staff and assist with safe patient removal using site-approved MRI safety procedures.
Expected outcome: The patient is not moved using a table system that may be unreliable.
Confirm the Reported Table Fault
Ask staff what occurred:
- Table will not move in or out
- Table movement stops unexpectedly
- Docking does not complete
- Table position is incorrect
- Drive motor noise is abnormal
- Table movement fault appears at the host
- Emergency stop was pressed
Expected outcome: The issue is clearly identified before troubleshooting begins.
Verify MRI Room Safety Conditions
Confirm that the scan room is safe to enter and that all tools, test items, and personal items are MRI-safe or kept outside Zone IV as required.
Expected outcome: Troubleshooting does not introduce projectile or safety risk.
Check for Patient, Accessory, or Obstruction Interference
Inspect the table path, dock area, side rails, coil cables, pads, straps, sheets, and patient accessories for anything blocking movement.
Expected outcome: The table path and docking area are clear.
If an obstruction is found and removed, retest table movement. If normal operation returns, stop troubleshooting.
Check Emergency Stop and Table Lock Conditions
Verify that any emergency stop, table stop, or movement inhibit condition has been cleared according to site procedure.
Confirm with MRI staff whether an emergency stop was activated during the event.
Expected outcome: Table movement is not being blocked by a safety stop condition.
Verify Table Docking Position
Inspect whether the patient table is fully seated, aligned, and properly docked at the magnet interface.
Look for partial docking, uneven table position, or physical misalignment.
Expected outcome: The table is mechanically aligned before drive movement is tested.
Check Table Communication and Indicator Behavior
Observe table control indicators, system messages, and host console alerts during a controlled movement attempt.
Note whether the system recognizes the table, reports a docking fault, or shows a drive/positioning error.
Expected outcome: The fault is narrowed to movement, docking, recognition, or position feedback.
Test Movement Without a Patient
With MRI staff approval, test table movement in a controlled condition with no patient present.
Use normal table controls and observe for:
- No movement
- Jerky or uneven motion
- Unexpected stopping
- Abnormal grinding or clicking
- Excessive resistance
- Host position mismatch
Expected outcome: The table moves smoothly through the expected range without abnormal sound or error.
If movement is restored and no errors return, document the finding and return the unit only after operational checks meet site policy.
Check External Cables and Connectors
Inspect accessible table-related cables, docking contacts, and external connection points for looseness, damage, debris, fluid contamination, or strain.
Do not force connectors or disassemble internal table components.
Expected outcome: External communication and power paths appear secure and undamaged.
Inspect for Physical Damage or Fluid Contamination
Check the table surface, base, dock area, drive track area, and accessible exterior panels for signs of impact, cracks, bent components, fluid intrusion, or unusual residue.
Expected outcome: No visible damage or contamination is present that could affect movement.
Check for Unusual Heat, Smell, or Noise
During limited testing, stop immediately if there is burning smell, unusual heat, repeated clicking, grinding, or motor strain.
Expected outcome: The table does not show signs of drive motor, brake, power, or mechanical failure during external troubleshooting.
Power Cycle Only if Appropriate
If MRI operations allow, have authorized MRI staff perform a controlled system/table reset or restart according to site procedure.
Do not interrupt scanning operations or restart the system without MRI staff coordination.
Expected outcome: Temporary software or communication faults clear after restart.
If the table fault clears and controlled movement checks pass, document the event and final status.
Verify Final Operational Status
Before returning the system to use, confirm:
- Table docks correctly
- Table moves in and out smoothly
- Position readout behaves normally
- No repeated alarms or host messages occur
- No abnormal noise, heat, smell, or resistance is present
Expected outcome: The MAGNETOM Skyra table is safe and reliable for clinical use.
If the Problem Persists
If table movement, docking, position feedback, or drive faults continue after external checks, the likely cause may involve internal drive components, sensors, brakes, table electronics, docking hardware, or system communication.
The MRI system or affected patient table should be removed from service, labeled Out of Service, and sent for Siemens-qualified service, repair, or bench evaluation.
Knowing when to stop is proper troubleshooting. Do not continue repeated table movement attempts if there is abnormal resistance, noise, heat, smell, or unreliable movement.
Clinical Use Tip
Do not troubleshoot table drive or docking faults with an active patient on the table unless the immediate goal is safe patient removal. Move the patient to another safe option first, then troubleshoot only when MRI staff confirm it is safe.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"MRI staff reported the Siemens MAGNETOM Skyra patient table would not dock fully and displayed a table movement fault at the console."
Cause
What was observed during troubleshooting.
Example:
"Found the docking area obstructed by a coil cable routed across the table interface, preventing full table seating."
Resolution
What action was taken.
Example:
"Removed the obstruction, verified table docking and in/out movement without a patient, confirmed no further table movement faults, and returned the system to service."
Helpful Details to Include (If Known)
- Whether the table was occupied when the fault occurred
- Exact host or console error message
- Whether the table would move in, out, both, or neither direction
- Docking status before and after troubleshooting
- Emergency stop or table stop status
- Coil cables, pads, sheets, or accessories found in the table path
- Any abnormal sound, vibration, heat, smell, or resistance
- External cable or connector condition
- Whether a restart was performed
- Final device status
Final Thought
Patient table faults on an MRI system should be handled carefully because they affect patient access, scanner availability, and safety. Start with simple external causes such as obstructions, docking alignment, emergency stop conditions, and visible cable issues. If the fault remains or movement is unreliable, stop and escalate for qualified repair. Clear CCR documentation helps show what was checked and why the device was returned to service or removed.
That is successful troubleshooting.
