What This Guide Helps With

Troubleshooting detector readiness, acquisition faults, calibration failures, or image receptor issues using safe external checks before repair escalation.

Step-by-Step Troubleshooting

Ensure Patient Safety First

Confirm no patient is positioned on the table and no fluoroscopy or radiographic exposure is being attempted.

If the issue occurs during an active exam, clinical staff should stop imaging and move the patient to another approved imaging workflow if needed.

Expected outcome: Troubleshooting begins only when the patient is safe and the system is not being used clinically.

Confirm the Exact Reported Fault

Ask the technologist what message appeared and when it occurred.

Determine whether the issue involves:

Expected outcome: The failure type is clearly identified before resets or accessory checks are performed.

Check System Readiness at the Operator Console

Review the system status on the Luminos Agile Max workstation or console.

Confirm whether the system is fully booted, logged in, and not waiting for a startup sequence, detector initialization, or room readiness condition.

Expected outcome: The system either shows ready status or provides a specific fault message to guide the next step.

Verify Table and Detector Position

Confirm the table, detector, tube assembly, and imaging chain are in a valid position for the selected exam or calibration.

A detector may show not ready if the imaging geometry is outside the expected position, the table is not properly parked, or the system cannot confirm alignment.

Expected outcome: The detector and imaging components are positioned correctly for the selected workflow.

If correcting the position clears the fault, verify normal operation and stop.

Check for Obstructions Around the Detector and Table

Inspect the table area, detector travel path, compression/accessory area if applicable, cables, foot controls, and nearby equipment.

Remove any objects that may block table movement, detector positioning, or system reference movement.

Expected outcome: No physical obstruction prevents detector positioning or system initialization.

Confirm Detector Area Is Free of Fluid, Debris, or Damage

Visually inspect the tabletop, detector cover, detector housing, and nearby seams for signs of fluid intrusion, impact damage, cracks, loose covers, or contamination.

Do not open covers or attempt internal inspection.

Expected outcome: No obvious external condition suggests damage or contamination affecting detector readiness.

If fluid intrusion, burning smell, unusual heat, or physical damage is present, remove the system from service and escalate immediately.

Check External Cables and Visible Connections

Inspect accessible external workstation, monitor, network, power, and peripheral cables.

Verify cables are seated, not pulled tight, kinked, pinched, or damaged.

Expected outcome: No loose or damaged external connection is causing acquisition or communication failure.

Verify Room Power and Workstation Power

Confirm the Fluoroscopy / Interventional System, acquisition workstation, monitors, and related equipment have power.

Check for tripped power strips, disconnected plugs, failed monitor power, or local outlet issues where applicable.

Expected outcome: All required system components are powered and stable.

Restart Only Through the Approved User-Level Shutdown Process

If the system is not in clinical use and the fault appears software-related, perform a controlled shutdown and restart using the site-approved procedure.

Do not perform hard power cycling unless approved by service documentation or site policy.

Expected outcome: The system reboots cleanly and detector initialization completes.

If the detector becomes ready and acquisition works normally after restart, document the reset and stop.

Confirm the Correct Exam and Acquisition Workflow

Verify that the selected exam, image mode, detector configuration, and acquisition workflow are appropriate for the procedure.

Incorrect workflow selection may prevent acquisition or calibration from starting correctly.

Expected outcome: The selected protocol supports the intended detector and acquisition mode.

Check Calibration Conditions

If calibration failed, confirm the calibration was attempted with the correct setup:

Expected outcome: Calibration conditions are valid before assuming detector failure.

Review Recent Changes

Ask whether the issue started after:

Expected outcome: Any likely trigger is identified and included in the service documentation.

Perform a Safe Test Acquisition Only If Allowed

If the system appears ready after checks, have qualified imaging staff perform a test acquisition or approved QC check according to site policy.

Clinical Engineering should not create unnecessary radiation exposure or bypass clinical imaging controls.

Expected outcome: Image acquisition completes successfully and image display is normal.

If the test acquisition passes and no faults return, return the device to service per site policy.

Check for Repeating Faults

If the detector becomes ready temporarily but the acquisition fault returns, document the exact message, timing, and whether the fault occurs during startup, positioning, fluoro, radiographic acquisition, or calibration.

Expected outcome: The pattern is captured for service escalation.

Do Not Continue Repeated Resets

If detector readiness, acquisition, or calibration faults continue after basic checks and one controlled restart, stop troubleshooting.

Repeated resets can delay patient care and may hide an intermittent detector, acquisition computer, communication, or calibration issue.

Expected outcome: The system is escalated appropriately instead of being forced back into service.

If the Problem Persists

If the detector remains not ready, calibration continues to fail, or image acquisition faults return after external checks, common external causes have been ruled out.

The issue may involve the flat detector, detector communication path, acquisition workstation, calibration data, imaging chain, power subsystem, or internal control electronics.

The device should be:

Knowing when to stop is proper troubleshooting. Do not attempt internal detector, generator, workstation, or calibration repairs unless trained and authorized for that service level.

Clinical Use Tip

Do not troubleshoot detector readiness or acquisition faults while a patient is positioned for imaging. Move the patient to another available fluoroscopy or radiology room first when clinical care cannot wait.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Technologist reported the Siemens Luminos Agile Max displayed “detector not ready” and would not acquire images during room setup."

Cause

What was observed during troubleshooting.

Example:
"Clinical Engineering found no patient present, verified room power, checked visible workstation and system connections, confirmed detector positioning, and observed the detector fault returned after a controlled restart."

Resolution

What action was taken.

Example:
"System was removed from service, labeled Out of Service, and escalated to Siemens service for detector/acquisition system evaluation."

Helpful Details to Include (If Known)

Final Thought

Detector and acquisition faults should be handled with a patient-safety-first approach. Start with power, positioning, visible connections, workflow setup, and calibration conditions before assuming internal failure. If the fault persists, remove the system from service and document the complaint, findings, and resolution clearly so repair support has a useful starting point.

That is successful troubleshooting.
