What This Guide Helps With
Troubleshooting MAGNETOM Aera patient table docking, movement, home-position, drive, alignment, or table communication issues from external causes.
Step-by-Step Troubleshooting
Ensure Patient Safety First
If the table is occupied, do not continue troubleshooting table motion until the patient is safe.
Move the patient off the table if table movement is unreliable, unexpected, obstructed, or unable to reach the required scan position.
Expected outcome: Patient safety is maintained before mechanical or positioning troubleshooting begins.
Confirm the Reported Table Fault
Ask clinical staff what happened and when the fault occurred.
Check whether the issue involves:
- Table will not dock
- Table will not undock
- Table will not move in or out
- Table will not raise or lower
- Table does not reach home position
- Table stops during movement
- Table position is not recognized by the system
- Error appears during patient setup or scan preparation
Expected outcome: The failure mode is clearly identified before parts or internal faults are suspected.
Check for Physical Obstruction Around the Table
Inspect the table path, docking area, table base, floor, rails, and surrounding equipment.
Remove any linens, straps, pads, coils, carts, footrests, step stools, cables, or patient accessories that may interfere with movement or docking.
Expected outcome: Table movement path is clear. If obstruction was the cause and table operation returns to normal, stop troubleshooting.
Verify the Table Is Properly Aligned for Docking
Confirm the table is straight, fully seated, and aligned with the scanner docking interface.
A table that is slightly misaligned may not latch, communicate, or be recognized correctly.
Expected outcome: Table docks smoothly and the system recognizes the docked position. If realignment resolves the issue, return the device to service after functional checks.
Inspect Docking Contacts and External Connection Points
Visually inspect the table docking interface for obvious debris, damage, bent contact areas, loose covers, or contamination.
Do not probe internal contacts or disassemble the docking assembly.
Expected outcome: Docking surfaces appear clean, intact, and unobstructed. If obvious external debris is found, remove it only if safe and appropriate.
Check Table Locks, Brakes, and Release Mechanisms
Verify any table lock, brake, release pedal, or dock/undock control is in the correct position.
Confirm the table is not mechanically locked out by a release handle, emergency release, or transport condition.
Expected outcome: Table controls and locks are in normal operating position.
Verify Power and System Readiness
Confirm the MRI system is powered, the host is responsive, and no active emergency stop or system inhibit condition is present.
Check for visible system messages that may prevent table motion, such as door/interlock, emergency stop, scan-room status, or system-not-ready conditions.
Expected outcome: Table movement is not being blocked by a system readiness or safety interlock condition.
Check the Operator Controls
Attempt table movement using the normal control method used by the site, such as the table-side controls, console controls, or system interface.
Compare whether one control location works while another does not.
Expected outcome: If one control works and another does not, document the failed control location and remove the device from full clinical use until evaluated.
Verify Home-Position Behavior
Attempt to return the table to home position using normal system controls.
Observe whether the table:
- Moves but does not complete home position
- Does not move at all
- Stops short
- Moves unevenly
- Reports an incorrect position
- Requires repeated attempts
Expected outcome: Table reaches home position and the system recognizes it correctly. If the home-position fault clears after normal repositioning, perform a repeat functional check before returning to service.
Check for Accessory or Coil Interference
Remove nonessential accessories from the table, including pads, positioning aids, coil holders, immobilization devices, and loose cables.
Confirm coils and cables are routed correctly and not catching during table travel.
Expected outcome: Table movement is smooth and unrestricted with accessories removed or properly routed.
Inspect for Fluid, Damage, Unusual Noise, Heat, or Smell
Look for signs of spilled fluids, impact damage, cracked covers, damaged wheels, dragging components, abnormal grinding, burning smell, or unusual warmth near table drive areas.
Do not continue operating the table if there are signs of mechanical damage or electrical overheating.
Expected outcome: No unsafe condition is present. If abnormal noise, heat, smell, or damage is found, remove the table/system from service.
Perform a Controlled Functional Check
With no patient on the table, test basic movement functions through a limited, controlled range.
Confirm docking, undocking, longitudinal movement, vertical movement if applicable, and home-position recognition.
Expected outcome: Table moves smoothly, stops correctly, docks securely, and reports position correctly.
Review Error Messages and System Logs Available to Clinical Engineering
Record the exact error message, fault code, timing, and table behavior.
Avoid clearing errors repeatedly without documenting them, especially if the fault returns.
Expected outcome: Enough information is captured to support vendor service or bench evaluation if the issue persists.
Determine Whether the Device Can Safely Return to Service
Return the system to service only if the table docks, moves, reaches home position, and is recognized consistently without abnormal noise, obstruction, or repeat errors.
Expected outcome: Device status is based on repeatable safe operation, not a single successful movement.
If the Problem Persists
If the MAGNETOM Aera table still will not dock, move correctly, reach home position, or communicate its position after external checks, common user-accessible causes have been ruled out.
The issue may involve the table drive, docking sensor, position encoder, table communication path, motor control, brake mechanism, or system interface.
The device should be:
- Removed from service
- Labeled Out of Service
- Sent for Siemens service, repair, or formal bench/system evaluation
Knowing when to stop is proper troubleshooting. Continued table operation with unresolved docking or positioning faults can create patient safety, scan setup, and equipment damage risks.
Clinical Use Tip
Do not troubleshoot table movement on an active patient. If table motion is unreliable, transfer the patient to another safe surface or use another MRI system if clinically necessary. Table faults should be verified only when the bore and table path are clear and patient safety is protected.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"MRI technologist reported the Siemens MAGNETOM Aera patient table would not dock and the system would not recognize the table at home position."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the table path clear, accessories removed, docking interface visually intact, but the table continued to stop short of home position during controlled testing."
Resolution
What action was taken.
Example:
"Removed the MRI system from service, labeled it Out of Service, documented the table behavior and error message, and escalated to Siemens service for table drive/docking evaluation."
Helpful Details to Include (If Known)
- Whether a patient was on the table when the fault occurred
- Exact table fault message or code
- Whether the issue was docking, movement, vertical lift, or home-position recognition
- Whether the table moved partially or not at all
- Whether the fault occurred at the console, table-side controls, or both
- Table alignment at docking
- Obstructions found or removed
- Coils, pads, or accessories installed at the time
- Indicator lights or system status messages
- Unusual sound, drag, heat, smell, or vibration
- Whether emergency stop or interlock conditions were active
- Final device status
Final Thought
MAGNETOM Aera table troubleshooting should stay focused on patient safety, clear movement paths, proper docking alignment, accessory interference, and repeatable system recognition. If the table cannot move or home reliably after external checks, escalation is the safe and correct action. Clear CCR documentation helps Siemens service and future Clinical Engineering review identify the failure pattern quickly.
That is successful troubleshooting.
