Scan Considerations

Care must be taken to avoid collision of the components with the scanner during scanning.

• Perform all scans according to the parameters given in the Scan Protocol.

• Acquire T1 weighted image sets.

• To avoid inaccuracies turn on 3D Distortion Correction and use the minimum bandwidth as stated in the Scan Protocol.

Patient Preparation

Follow the sterile draping instructions in the Cranial/ENT Optical Instrument User Guide.

Ensure that there is no relative movement between the patient’s head and reference array after registration (e.g., through the following):

• Movement of the patient’s head in the head clamp
• Movement of the reference array
• Movement of the registration matrix
