What This Guide Helps With
Identifies common external causes of poor image quality, including probe issues, settings, patient interface, and system environment.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Confirm no patient is actively connected.
Expected outcome: Safe environment for troubleshooting.
Inspect the Probe and Cable
- Examine the probe for cracks, debris, or damage. Ensure the cable is fully seated in the correct port.
Expected outcome: Visible damage noted or reconnection resolves artifacts.
Clean the Probe Surface
- Use approved gel and cleaning solutions to remove residue or dried gel.
Expected outcome: Clean surface eliminates streaks, dropouts, or echo artifacts.
Check System Settings
- Verify frequency, depth, gain, and imaging presets match the study type. Reset to default if unsure.
Expected outcome: Artifacts reduce or image clarity improves.
Perform a System Reboot
- Power cycle the unit to clear temporary software or memory issues.
Expected outcome: Improved image stability; temporary software glitches cleared.
Test With a Known Good Probe
- Swap with a verified functioning probe to isolate probe vs. system issue.
Expected outcome: If image improves, original probe is likely at fault.
Verify Environment
- Check for electromagnetic interference (other devices nearby) and ensure proper room lighting.
Expected outcome: Reduced environmental artifact.
If the Problem Persists
External checks have been ruled out. The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
Knowing when to stop prevents patient risk and wasted troubleshooting time.
Clinical Use Tip
Always move the patient to another imaging system before extensive troubleshooting. Never attempt while scanning an active patient.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported streaking and blurry regions on ultrasound images."
Cause
What was observed during troubleshooting.
Example:
"Probe tip had residual gel buildup and improper seating in the port."
Resolution
What action was taken.
Example:
"Probe cleaned, reconnected, and system rebooted; image quality restored."
Helpful Details to Include (If Known)
- Indicator lights on probe and system
- Unusual sounds or heat from system
- Gel residue or cracks on probe
- Imaging preset settings
- Final device status after troubleshooting
Final Thought
Patient safety comes first. Troubleshooting should follow logical steps from simplest to more involved checks. Escalate appropriately, document findings thoroughly, and ensure device readiness for patient use.
That is successful troubleshooting.
