A generic maintenance schedule should not replace manufacturer-specific requirements.
2. Monitor Error Codes
Repeated error codes can provide valuable information about developing equipment problems.
Record:
- Error code
- Date
- Time
- Operating condition
- Frequency
- Actions taken
A pattern of recurring errors should be investigated rather than repeatedly reset.
3. Inspect the Cooling System
Cooling performance is critical for CT equipment.
Technicians may inspect applicable:
- Cooling circuits
- Fans
- Pumps
- Heat exchangers
- Filters
- Temperature sensors
- Environmental conditions
Cooling-system requirements vary by manufacturer and model.
4. Check the X-Ray Tube
Tube-related maintenance should follow the manufacturer’s approved procedures.CT Scanner Repair and Maintenance.
Potential warning signs include:
- Tube overheating
- Repeated tube-related errors
- Longer cooling periods
- Unexpected scan interruptions
- Abnormal operating behavior
A qualified service engineer should diagnose persistent tube problems.
5. Inspect Gantry Movement
The gantry must rotate smoothly and accurately.
Unusual vibration, noise, or movement should be investigated.
6. Check the Patient Table
Table movement is important for accurate patient positioning.
Maintenance can include checking movement, positioning accuracy, mechanical condition, and safety features.
7. Perform Required Calibration
Calibration helps maintain appropriate system performance.
The required calibration procedures depend on the scanner manufacturer and model.
8. Monitor Image Quality
Changes in image quality can indicate many possible issues.
Potential symptoms include:
- Increased noise
- Artifacts
- Non-uniformity
- Ring artifacts
- Streaks
- Unexpected image changes
Image-quality issues require systematic diagnosis rather than assuming a single component is responsible.
9. Review Service and Maintenance Records
Maintain a history of:
- Repairs
- Error codes
- Calibration
- Preventive maintenance
- Component replacement
- Tube replacement
- Service visits
A complete maintenance history helps engineers identify recurring problems.
10. Schedule Professional Preventive Maintenance
Professional preventive maintenance should be performed according to the manufacturer’s recommendations and the healthcare facility’s maintenance program.
