What This Guide Helps With
Image acquisition failure, incomplete exams, detector communication issues, workstation problems, or workflow interruptions on a Carestream DRX-Evolution system.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
Do not troubleshoot the DRX-Evolution while the patient is positioned for an active exam unless the issue is minor and does not delay care.
Action:
- Remove the patient from the imaging position if the exam cannot continue safely.
- Notify clinical staff that the room is experiencing an acquisition or workflow issue.
- Use another radiographic room or portable system if imaging is urgent.
Expected outcome: Patient care continues without relying on a system that may not complete the exam.
Why it matters: Image acquisition failures can delay diagnosis, increase repeat positioning, or lead to unnecessary repeat exposure attempts.
2. Verify the Reported Failure
Confirm exactly where the exam is failing.
Action:
- Ask the technologist what happened:
- Was the exposure not captured?
- Did the image fail to appear?
- Did the exam freeze before completion?
- Did the detector fail to connect?
- Did the image acquire but not save?
- Did the study fail to close or send?
Expected outcome: The failure point is identified before replacing accessories or escalating.
If the issue is resolved after correcting workflow or restarting the exam, stop.
3. Check for Active Error Messages or System Prompts
Look for visible messages on the acquisition workstation, generator console, detector status area, or room control interface.
Action:
- Record the exact error message.
- Check whether the system is asking for detector selection, patient/exam confirmation, room selection, cassette registration, or exposure readiness.
Expected outcome: Any displayed fault is documented and used to guide the next step.
Why it matters: Many image acquisition failures are caused by incomplete workflow steps rather than hardware failure.
4. Confirm the Correct Patient and Exam Are Selected
Verify that the correct patient, accession number, body part, projection, and detector are selected before exposure.
Action:
- Confirm the exam is open and active on the acquisition workstation.
- Confirm the correct image receptor/detector is assigned.
- Confirm the projection is selected and ready for acquisition.
Expected outcome: The system is ready to receive the exposure under the correct exam.
If the technologist had the wrong exam, projection, or detector selected and correcting it allows acquisition, stop.
5. Check Detector Status and Connection
Verify that the DRX detector is available, powered, connected, and assigned to the room.
Action:
- Check detector battery level.
- Confirm detector wireless or wired connection status.
- Verify the detector is not assigned to another room, portable system, or exam.
- Remove and reinsert the detector battery if approved by department workflow.
- Place the detector in its charger or dock briefly if the battery or connection status is questionable.
Expected outcome: Detector status changes to ready, connected, or available.
If the detector reconnects and the exam completes normally, stop.
6. Inspect Detector Battery and Charging Contacts
Check for a low battery, loose battery, damaged battery latch, or dirty/damaged charging contacts.
Action:
- Swap with a known-good charged detector battery if available.
- Inspect battery seating.
- Confirm the detector powers on normally.
- Check for obvious physical damage, swelling, cracked housing, or liquid intrusion.
Expected outcome: Detector power is stable and the detector remains connected during acquisition.
If a battery swap resolves the issue, document the failed battery and remove it from use.
7. Check Room Network and Workstation Connectivity
Confirm the acquisition workstation has network communication and is not disconnected from required hospital or imaging systems.
Action:
- Check network cable connections at the workstation if accessible.
- Verify link lights at the network jack or switch connection if visible.
- Confirm other network-dependent functions are working, such as worklist refresh or PACS destination availability.
Expected outcome: The workstation has stable network communication.
Why it matters: Some exams may acquire locally but fail to complete, close, or transfer if network communication is interrupted.
8. Restart the Acquisition Application
If the workstation appears frozen, delayed, or stuck in the exam workflow, restart the acquisition software if safe and allowed by site procedure.
Action:
- Close the exam if possible.
- Exit and restart the acquisition application.
- Reopen the patient exam and attempt a test workflow without exposing a patient.
Expected outcome: The software responds normally and allows the exam workflow to continue.
If the application restart resolves the issue, document the software lockup and final status.
9. Power Cycle the Workstation and Room System
If the system remains locked, not ready, or unable to complete acquisition, perform a controlled restart.
Action:
- Confirm no patient is being imaged.
- Shut down the acquisition workstation properly.
- Power cycle the workstation and applicable room controls according to local procedure.
- Allow all components to fully boot and reconnect.
Expected outcome: The workstation, detector, generator, and room system return to normal ready status.
If the system completes a test acquisition after restart, stop.
10. Verify Generator and Exposure Readiness
Check whether the acquisition failure is actually caused by the generator not completing exposure.
Action:
- Confirm the generator is ready.
- Check for exposure inhibit messages.
- Verify tube stand, wall stand, table bucky, grid, and detector selection match the requested exam.
- Confirm no emergency stop, door interlock, tube lock, or positioning interlock is active.
Expected outcome: The system reaches exposure-ready status before image acquisition is attempted.
Why it matters: If the generator never completes exposure, the workstation may appear to have an image acquisition problem even though the exposure was inhibited.
11. Check Bucky, Table, Wall Stand, and Detector Selection
Confirm the selected receptor matches the physical imaging setup.
Action:
- Verify whether the exam is using the table bucky, wall bucky, or wireless detector.
- Confirm the detector is properly seated if using a bucky tray.
- Check that the selected receptor on the workstation matches the detector position.
Expected outcome: The system is not waiting for a different image receptor than the one being used.
If correcting receptor selection resolves the failed acquisition, stop.
12. Perform a Non-Patient Test Image if Permitted
After patient safety is addressed, perform a controlled test exposure using site-approved phantom or QA process.
Action:
- Use a test patient or QA workflow if allowed by facility policy.
- Confirm the detector captures the image.
- Confirm the image displays on the workstation.
- Confirm the exam can be completed, saved, and sent if needed.
Expected outcome: The acquisition chain is verified from exposure through image display and completion.
Do not perform unnecessary radiation exposures outside approved testing procedures.
13. Check for Repeat Failure Pattern
Determine whether the issue is isolated or repeatable.
Action:
- Confirm whether the problem occurs with:
- One detector only
- One room position only
- One exam type only
- One technologist login only
- All exams
- All detectors
Expected outcome: The failure pattern helps determine whether the issue is detector-related, workstation-related, generator-related, network-related, or workflow-related.
14. Remove Failed Accessories from Service
If one detector, battery, cable, charger, or network cable is clearly associated with the failure, remove that item from use.
Action:
- Label the suspect accessory.
- Document the serial number if available.
- Test the system with a known-good accessory.
Expected outcome: The room is returned to service only if the remaining configuration passes functional testing.
If the issue follows the accessory, send the accessory for repair or replacement.
If the Problem Persists
If the Carestream DRX-Evolution still cannot acquire images or complete exams after checking patient safety, exam workflow, detector status, battery condition, receptor selection, workstation behavior, network connection, and generator readiness, common external causes have been ruled out.
The system should be removed from service, labeled Out of Service, and sent for repair, vendor support, or bench/system evaluation.
Do not continue repeated exposure attempts or workflow resets if the failure is repeatable. Knowing when to stop is proper troubleshooting.
Clinical Use Tip
Do not troubleshoot image acquisition failures while a patient is waiting in position unless the correction is immediate and safe. Move the patient to another room or imaging device first if care could be delayed. Maintain therapy and imaging continuity by using a backup device or approved alternate workflow before continuing troubleshooting.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Technologist reported the Carestream DRX-Evolution would not complete the exam after exposure, and the acquired image did not display on the workstation."
Cause
What was observed during troubleshooting.
Example:
"Found the wireless DRX detector intermittently disconnecting due to a depleted detector battery."
Resolution
What action was taken.
Example:
"Replaced the detector battery with a charged known-good battery, confirmed detector connection, completed a test acquisition, and returned the room to service."
Helpful Details to Include (If Known)
- Alarm behavior, exact error message, or prompt displayed
- Accessories swapped, including detector battery, detector, cable, charger, or network cable
- Power behavior, including outlet or room power status and acquisition workstation restart
- Environmental factors, including whether the issue affected one detector, one room position, one exam type, one technologist login, all exams, or all detectors
- Indicator lights, including wired or wireless detector status, network link lights, generator ready status, or exposure inhibit status
- Final device status, including whether the room was returned to service or removed from service
Final Thought
Image acquisition failures should be handled logically from the outside in. Protect the patient first, verify workflow and detector status, check power and communication, then confirm whether the generator actually completed exposure. If the problem remains repeatable after basic checks, remove the DRX-Evolution from service and escalate with clear CCR documentation.
That is successful troubleshooting.
