9.4.5 Laser Beam Aligning – Third Molar (optional)
This feature is the only available option in some Asian
countries and Mexico.
Be careful not to shine the Laser Beam directly into the
person's eyes. Doing so may result in vision loss.
If the Laser Beam is not correctly positioned, there may
be distortion, causing the image to be enlarged or
reduced, or ghost shadows may occur and lower the
image quality. Be sure to align Laser Beam properly.
This is a sample illustration for reference only. Actual FOV
may vary from the image, as shown above.
2. Align the center of the examinee's face according to the center alignment
guideline.
3. Using a horizontal beam, correct the sagging or lifting of the patient's head.
9.4.6 Finishing Patient Positioning
1. After checking the positions of the patient and the Laser Beam, prevent the
patient's head from moving.
2. Click the READY button. X-ray exposure has not started yet.
3. Now go to 9.5 X-ray Exposure to start the exposure.
