Precautions for Using the Carestream CS9300C Dental CBCT

1. Pre-Use Preparation

1. Operator Training
   Operators must undergo professional training to become familiar with system operation, parameter settings, safety protocols, and patient communication.

2. Patient Identification and Preparation

   • Confirm patient identity and verify imaging orders.

   • Check for contraindications (e.g., pregnancy).

   • Ask the patient to remove any metallic objects from the head and neck region, including earrings, necklaces, dental prosthetics, hairpins, etc., to prevent image artifacts.

1. Equipment Check

1. Inspect power supply, system status, and software connectivity.

2. Ensure that the X-ray tube, detector, and rotating gantry are functioning normally.

3. Clean and disinfect all patient-contact surfaces (e.g., headrests, chin supports).

2. During Operation

1. Patient Positioning

   • Use the three-point positioning system (ear rods, forehead support, and bite block) to ensure head stability.

   • Adjust patient posture to center the region of interest for clear imaging.

   • Instruct the patient to remain still and keep the mouth closed during the scan.

1. Parameter Selection

1. Choose the appropriate field of view (FOV) based on clinical needs (e.g., 5×5 cm for a single tooth, 10×10 cm for full arch).

2. Set resolution (high, medium, or low) and exposure parameters (kV/mA) appropriately to balance image quality and radiation dose.

1. Operator Protection

1. Operators must stay in a protected area during exposure to avoid radiation.

2. Use lead shielding or remote control software to operate the scan safely.

1. Scanning Execution

1. Double-check scan parameters and patient positioning before starting.

2. Monitor the patient throughout the scan to detect any movement or discomfort.

3. Post-Use Procedures

1. Image Processing and Storage

   • Perform necessary image reconstruction and adjustments.

   • Store the images in the PACS or local database and ensure backup copies are created.

1. System Maintenance

1. Clean all contact surfaces after each use and conduct routine maintenance.

2. In case of anomalies, report the issue and contact technical support promptly.

1. Record Keeping

1. Maintain a usage log including patient information, scan settings, and operator ID for auditing and traceability.

4. Common Issues and Troubleshootin

Issue

Blurry Images

Image Artifacts

Scan Failure

Issue

5. Safety and Compliance

• Adhere to local radiation safety and management regulations, and minimize patient exposure.

• Perform regular radiation leakage checks and equipment performance assessments in accordance with national standards.

• Implement strict occupational protection protocols to prevent operator overexposure.
