What This Guide Helps With

Troubleshooting collimator, tube stand, SID, table, or positioning errors using safe external checks before repair escalation.

Step-by-Step Troubleshooting

Ensure Patient Safety First

Confirm whether a patient is on the fluoroscopy table or positioned for an exam.

Stop all table, tube stand, detector, and collimator movement if positioning is unreliable, restricted, or unexpected.

Expected outcome: Patient, staff, lines, tubing, contrast equipment, and room accessories are protected from unintended movement.

If the system cannot move safely or the patient cannot be repositioned safely, stop troubleshooting and escalate immediately.

Confirm the Exact Reported Positioning Issue

Ask the technologist what failed and when it occurred.

Identify whether the issue involves:

• Collimator blades not moving
• Light field not working
• Field size not matching expected image area
• Tube stand movement fault
• SID value not updating
• Table positioning error
• Detector or image receptor alignment issue
• Positioning lock, brake, or limit message
• Movement inhibited during fluoro or radiography setup

Expected outcome: The affected function is clearly identified before troubleshooting begins.

Check for Active System Messages or Inhibits

Review the operator display, system console, and workstation messages for positioning, collimator, SID, table, or movement-related alerts.

Do not clear or dismiss messages without recording them.

Expected outcome: The fault message is captured and used to guide safe troubleshooting.

Verify the System Is Not in an Unsafe or Restricted Movement State

Confirm the table, tube stand, detector, and room equipment are not at a mechanical limit, collision zone, parked position requirement, or workflow-restricted position.

Move only through normal operator controls and only when the area is clear.

Expected outcome: The system either resumes normal movement or confirms a repeatable positioning fault.

If movement returns to normal after moving out of a limit or restricted position, verify operation and stop.

Inspect the Area Around the Table, Tube Stand, and Detector

Look for physical obstructions around the table base, tabletop, foot area, detector carriage, tube stand, wall stand if applicable, and ceiling or floor-mounted accessories.

Check for stools, foot pedals, cables, IV poles, contrast injector lines, monitor arms, step platforms, or stored supplies blocking movement.

Expected outcome: No external object is preventing normal system positioning.

If an obstruction is removed and positioning works normally, document the cause and stop.

Check Emergency Stop and Safety Controls

Verify that any emergency stop buttons, movement release controls, or room safety switches are not engaged.

Reset only according to site policy and normal operator workflow.

Expected outcome: The system is not being intentionally held in a safety-stop condition.

If resetting a safety stop restores movement, confirm full safe operation before returning to use.

Verify Operator Control Inputs

Test the affected movement using the appropriate normal control, such as table controls, tube stand controls, collimator controls, or room-side controls.

If more than one control location is available, compare operation from each location.

Expected outcome: The issue is narrowed to the device function itself or to a specific control station.

If one control station works and another does not, remove from service or limit use according to site policy until the defective control is evaluated.

Check Footswitches, Hand Controls, and Cables

Inspect external cables, connectors, control pendants, footswitches, and hand controls for damage, loose connections, liquid exposure, pinching, or strain.

Reseat accessible external connectors only if they are intended to be user-accessible and can be handled safely.

Expected outcome: External control accessories are connected, intact, and not causing intermittent movement commands or inhibits.

Verify Collimator Function Externally

Check whether the collimator light field turns on, shutters respond, field size changes, and displayed collimation information appears reasonable.

Do not attempt internal collimator repair or adjustment.

Expected outcome: Collimator movement and light field behavior are confirmed through normal operator checks.

If the collimator is stuck, noisy, misaligned, or does not match the displayed field, remove the system from clinical use and escalate.

Confirm SID and Position Readout Behavior

Check whether the SID value changes appropriately when the tube stand, table, or detector position changes.

Compare the displayed SID with the expected physical position from the exam setup.

Expected outcome: SID indication updates consistently and matches expected positioning.

If the SID is frozen, clearly incorrect, or intermittently changes, suspect a position sensor, encoder, or communication issue and escalate.

Check Table and Tube Stand Locks or Brakes

Verify the table, tabletop, and tube stand are not locked in a position that prevents motion.

Confirm brakes release and reapply normally through standard controls.

Expected outcome: The system can move and lock securely without drifting, sticking, or unexpected release.

If brakes fail to hold, fail to release, or make abnormal noise, remove the system from service.

Review Recent Room or Workflow Changes

Ask whether the issue began after cleaning, accessory change, software restart, power event, room move, detector change, service visit, or exam protocol change.

Expected outcome: A recent external change may explain the positioning issue.

If the issue began immediately after an accessory or workflow change, reverse the change if safe and verify operation.

Restart the System Only if Clinically Appropriate

If no patient is active and the clinical team agrees, perform a normal system restart using the site-approved shutdown and startup process.

Do not power-cycle during an active exam unless directed by site emergency policy.

Expected outcome: Temporary control or communication faults may clear after a controlled restart.

If the fault returns after restart, continue escalation.

Perform a Limited Functional Check

With no patient present, verify basic safe movement and setup functions:

• Table movement
• Tube stand positioning
• Detector alignment
• SID readout
• Collimator response
• Light field operation
• Movement locks and brakes
• Any displayed positioning messages

Expected outcome: The system either passes a basic operational check or the fault is confirmed as repeatable.

If all functions pass and no error returns, document the checks completed and return to service only according to site policy.

If the Problem Persists

If the positioning, collimator, tube stand, SID, brake, or table issue continues after external checks, common user-accessible causes have been ruled out.

The issue may involve an internal position sensor, encoder, motor drive, brake assembly, collimator mechanism, control circuit, calibration, or system communication fault.

The device should be:

• Removed from service
• Labeled Out of Service
• Sent for repair, vendor service, or bench/system evaluation

Knowing when to stop is proper troubleshooting. Do not continue clinical use if system position, collimation, SID accuracy, or movement safety cannot be verified.

Clinical Use Tip

Do not troubleshoot table, tube stand, detector, or collimator movement on an active patient unless it is necessary for immediate patient safety. Move the patient to another imaging room or approved downtime workflow before continuing non-urgent troubleshooting.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Technologist reported the Luminos Agile Max displayed a SID positioning error and would not allow normal fluoroscopy setup."

Cause

What was observed during troubleshooting.

Example:
"External inspection found the tube stand was at a movement limit with the detector not aligned to the expected exam position."

Resolution

What action was taken.

Example:
"Cleared the positioning setup, verified table and tube stand movement, confirmed SID readout updated normally, and returned the system to service after functional check."

Helpful Details to Include (If Known)

• Patient present or no patient present during failure
• Exact error message or code displayed
• Whether collimator blades moved normally
• Whether the light field operated
• Whether SID value updated correctly
• Table position and tube stand position at time of failure
• Any movement limit, brake, or lock message
• Footswitch, hand control, or room control behavior
• Obstructions found near table, detector, or tube stand
• Abnormal noise, sticking, drifting, heat, or smell
• Whether restart was performed
• Final device status

Final Thought

For fluoroscopy positioning problems, patient safety comes first because table, tube stand, detector, and collimator faults can directly affect patient positioning, image quality, and radiation field control. Start with external causes, verify safe movement and alignment, and escalate when position accuracy or motion safety cannot be confirmed. Clear CCR documentation protects the patient, the clinical team, and the repair process.

That is successful troubleshooting.
