What This Guide Helps With
Identifies external causes of image artifacts, such as improper positioning, loose cables, or interference, ensuring clear fluoroscopic imaging and patient safety.
Step-by-Step Troubleshooting
Ensure Patient and Staff Safety
- Confirm no patient is on the table and staff are clear.
Why: Prevents accidental exposure during troubleshooting.
Inspect Display and Monitor Settings
- Check for correct image mode, brightness, contrast, and active presets.
Expected Outcome: Image settings match clinical protocol; some artifacts may resolve with adjustments.
Verify Detector and Cable Connections
- Inspect flat panel or image intensifier connections for looseness or damage.
Expected Outcome: Secure connections may eliminate intermittent artifacts.
Check for External Interference Sources
- Remove or power down nearby devices that may emit electromagnetic interference.
Expected Outcome: Artifacts caused by interference should clear.
Inspect Collimator and Filters
- Ensure collimator blades move freely and filters are properly seated.
Expected Outcome: Misaligned collimators can produce shading or lines on images.
Perform System Reboot
- Power down the system following proper shutdown procedure, then restart.
Expected Outcome: Temporary software glitches causing artifacts may be resolved.
If the Problem Persists
External causes have been ruled out. The artifact is likely due to internal detector issues or X-ray tube alignment.
Remove the system from service.
Label Out of Service and send for repair or bench evaluation.
Reminder: Knowing when to escalate protects patient safety and preserves system integrity.
Clinical Use Tip
Never perform troubleshooting while a patient is on the table.
Use an alternative imaging system if urgent procedures are required.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Fluoroscopic images show horizontal lines and shading artifacts."
Cause
What was observed during troubleshooting.
Example:
"Flat panel detector cable found partially loose; no external interference detected."
Resolution
What action was taken.
Example:
"Reconnected detector cable; performed system restart; artifacts resolved."
Helpful Details to Include (If Known)
- Check for loose cables or connectors
- Record specific artifact pattern and location
- Document any system reboots
- Note if software updates were pending
- Confirm final device status
Final Thought
Maintaining image quality is essential for patient safety and diagnostic accuracy. Troubleshoot methodically, escalate appropriately, and document all findings to support clinical and engineering decision-making.
That is successful troubleshooting.
