What This Guide Helps With
Image transfer, cassette/detector recognition, or workstation communication issues preventing images from reaching review or PACS systems.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Do not troubleshoot image transfer or detector communication problems during an active patient exam if repeat exposure risk is present.
Action:
- Remove the mobile X-ray unit from patient use if images are not transferring, the detector is not recognized, or exposures may need to be repeated.
- Use another mobile X-ray system if imaging is clinically urgent.
Expected outcome: Patient care continues without unnecessary delay or avoidable repeat radiation exposure.
Why it matters: Communication failures can lead to missing images, repeated exposures, delayed diagnosis, or incomplete exam documentation.
Verify the Reported Problem
Confirm exactly where the failure occurs.
Action:
- Ask clinical staff what happened:
- Did the detector fail to connect?
- Did the exposure complete but no image appeared?
- Did the image appear locally but fail to send?
- Did the image reach the workstation but not PACS?
- Did an error message appear?
Expected outcome: The issue is narrowed to detector connection, image acquisition, workstation transfer, or network/PACS communication.
If the problem is only with PACS transfer but images are stored locally, do not assume the detector or generator failed.
Confirm the Correct Detector or Cassette Is Being Used
Verify that the detector, cassette, or image receptor belongs with the unit and is approved for that system configuration.
Action:
- Check the detector ID, cassette labeling, and assigned room/unit if applicable.
- Confirm staff did not swap detectors between mobile units.
Expected outcome: The AMX system is being used with the correct detector or cassette.
If the wrong detector was used, return the correct detector to the unit, repeat detector recognition if required, and stop if communication is restored.
Check Detector Power and Battery Status
For wireless detector configurations, confirm the detector has adequate battery charge.
Action:
- Check detector battery indicators or workstation detector status.
- Install a known-charged detector battery if available.
- Seat the battery fully and inspect for obvious latch or contact issues.
Expected outcome: The detector powers on and becomes available to the mobile unit.
If the detector reconnects after battery replacement or reseating, document the battery condition and stop.
Inspect Detector or Cassette for Physical Damage
Check for obvious external damage before continuing.
Action:
- Inspect the detector/cassette for cracks, bent corners, loose covers, damaged handles, fluid exposure, or signs of impact.
- Check connector areas if a tethered or docking connection is used.
Expected outcome: No visible physical damage is present.
If damage is found, remove the detector from service and send it for repair evaluation. Do not continue using a damaged detector for patient imaging.
Verify Detector Seating, Docking, or Cable Connection
If the AMX configuration uses a docking bay, tether, reader, or cassette interface, check all external connections.
Action:
- Reseat the detector or cassette.
- Confirm the detector is fully docked or inserted.
- Inspect external cables for loose connections, bent pins, damaged strain reliefs, or broken latch points.
- Swap with a known-good external cable if available and appropriate.
Expected outcome: The detector/cassette is recognized by the system.
If reseating or cable replacement resolves the issue, document the failed connection or cable and stop.
Restart the Image Acquisition Application
A software session may be frozen even when the mobile unit itself is powered.
Action:
- Close and reopen the image acquisition software if accessible.
- Log out and back in if the workflow allows.
- Avoid deleting exams or images unless following site policy.
Expected outcome: The acquisition workstation reconnects to the detector and resumes normal workflow.
If the detector or image queue returns after restarting the application, verify image transfer with a test or non-patient workflow and stop.
Power Cycle the Mobile X-Ray Unit Safely
If the detector and connections appear normal, perform a controlled restart.
Action:
- Confirm no patient exam is in progress.
- Shut down the AMX system through the normal shutdown process.
- Wait briefly, then power the system back on.
- Observe startup for detector, workstation, or network errors.
Expected outcome: The unit boots normally and communication is restored.
If the issue clears after restart, document it as an intermittent communication/software lockup and monitor for recurrence.
Check Local Image Storage or Exam Queue
Determine whether images are being captured but not transferred.
Action:
- Check whether the completed images are visible locally on the acquisition workstation.
- Review the send queue, pending queue, failed queue, or exam list if available.
- Look for failed sends, retry prompts, or unsent studies.
Expected outcome: You can tell whether acquisition failed or transfer failed after acquisition.
If images are stored locally but not sending, focus on network, destination, AE title, worklist, or PACS communication rather than detector hardware.
Verify Network Connection
Mobile X-ray units often depend on wireless or wired network connection for worklist and image transfer.
Action:
- Check wireless signal status or wired network connection if docked.
- Confirm the unit is in an area with known wireless coverage.
- Move the unit closer to a known-good wireless area if appropriate.
- Check whether other mobile X-ray units are transferring images successfully.
Expected outcome: The AMX has active network connectivity.
If transfer works in another area, document possible wireless coverage or network access issue and notify IT/PACS support as needed.
Confirm Worklist and Patient Data Communication
If the issue involves missing patients or failed worklist lookup, separate worklist communication from image transfer.
Action:
- Check whether the unit can query the modality worklist.
- Confirm date, time, accession number, patient ID, and exam selection are correct.
- Compare with another working mobile unit if available.
Expected outcome: Worklist communication is confirmed or identified as failed.
If worklist is unavailable but image transfer still works manually, document the issue as a worklist communication problem rather than detector failure.
Check Destination or PACS Transfer Status
If images acquire locally but do not reach PACS, verify destination communication.
Action:
- Check send status on the workstation.
- Retry sending the study if site policy allows.
- Confirm the correct destination is selected.
- Ask PACS/IT whether PACS, DICOM routing, wireless network, or storage destination issues are occurring.
Expected outcome: The failure is identified as local device communication or downstream PACS/network issue.
If multiple imaging devices are affected, escalate to IT/PACS rather than treating the AMX as the primary failure.
Check for Date, Time, or System Identification Issues
Incorrect system time or identification can interfere with worklist matching, image routing, and exam reconciliation.
Action:
- Check date and time displayed on the unit.
- Confirm the unit identity, location, or configured destination has not changed unexpectedly.
- Do not alter network or DICOM configuration unless authorized.
Expected outcome: The unit has correct time, identity, and exam routing behavior.
If configuration appears incorrect, escalate to imaging IT, PACS administrator, or service support.
Test With a Known-Good Detector or Workflow
If available, use a known-good detector, cassette, battery, or test workflow to isolate the fault.
Action:
- Use only approved site procedures and compatible components.
- Compare behavior using:
- Known-good detector battery
- Known-good detector/cassette
- Known-good network location
- Known-good test exam workflow
Expected outcome: The issue follows either the detector/cassette, the mobile unit, or the network/workstation path.
If the fault follows the detector, remove the detector from service.
If the fault stays with the AMX unit, remove the unit from service for bench evaluation.
If the fault follows network location or routing, escalate to IT/PACS.
Review Error Messages and Logs Without Deep Service Action
Record any displayed communication, detector, workstation, image transfer, or DICOM errors.
Action:
- Photograph or write down the exact error message.
- Record when the error occurs:
- At startup
- During detector connection
- After exposure
- During image processing
- During send to PACS
- During worklist query
Expected outcome: Repair, PACS, or vendor support has useful details for troubleshooting.
Do not perform deep internal service, board replacement, or configuration changes unless trained and authorized for that GE AMX configuration.
If the Problem Persists
If detector power, cassette seating, external cables, software restart, network status, worklist behavior, and PACS transfer status have been checked, common external causes have been ruled out.
The problem is likely related to an internal detector interface, acquisition workstation, wireless communication module, software/database issue, DICOM configuration, or internal system communication fault.
The device should be removed from service, labeled Out of Service, and sent for repair, bench evaluation, imaging IT review, or vendor support as appropriate.
Knowing when to stop is proper troubleshooting. Continuing to force imaging attempts can create repeat exposure risk, lost images, incomplete exams, and clinical delays.
Clinical Use Tip
Do not troubleshoot image transfer problems while a patient is waiting on the same unit if another mobile X-ray system is available. Move the exam to a known-working unit first, especially when repeat imaging may increase radiation exposure or delay care. Maintain therapy and imaging continuity by using a backup device before troubleshooting continues.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the GE AMX mobile X-ray system completed exposure but images did not transfer to the workstation/PACS."
Cause
What was observed during troubleshooting.
Example:
"Troubleshooting found the detector was recognized locally, but completed studies remained in the failed send queue due to network/PACS communication failure."
Resolution
What action was taken.
Example:
"Verified detector battery, reseated external connections, restarted the acquisition workstation, confirmed local image storage, documented failed transfer behavior, and escalated to PACS/IT while removing the unit from service pending verification."
Helpful Details to Include (If Known)
- Outlet or charging status checked
- Detector/cassette ID verified
- Detector battery status
- Detector physically inspected
- Docking bay or tether cable reseated
- Known-good battery or detector tested
- Error message recorded
- Image appeared locally or did not appear locally
- Send queue status
- Worklist query status
- Wireless or wired network status
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Whether other mobile units were affected
- Whether images eventually reached PACS
- Final device status
Final Thought
Image transfer and detector communication failures should be handled logically. Start with patient safety, then verify the detector, battery, cassette, cables, software session, network connection, and PACS/worklist path. If external causes are ruled out, remove the unit from service and escalate with clear CCR documentation so repair, PACS, or IT support can act quickly.
That is successful troubleshooting.
