6. From the Pan menu, make an
Exposure selection: The
Operator is required to
determine the Patient’s head
size.
Small is normally selected
for young children and small
elderly females.
Large is for a
normal size adult or large child
(head size).
7. Patient Position : click the Open
beam limiter box to access the
laser light for Patient tilt
positioning.
With this box checked, the
collimator opens so the lasers
are available for Patient tilt
positioning.
8. Align the Patient Occlusal Plane
so that it is level with the
Horizontal Laser. Then have the
Patient tilt their head downward
approximately 10
o
.
Refer to the illustration above for a visual of tilting the Patient.
Using the Sagittal Laser (front center laser), ensure that the
Patient is centered and facing straight foward.
9. After the Patient is properly positioned, uncheck the Open beam
limiter box. This closes the collimator.
NOTE:
Note: If Operator fails to uncheck the Open beam limiter box
prior to clicking Capture, the system unchecks the box which closes
the collimator prior to starting the scan.
10. The Patient’s lips should be closed around the bite piece as if
using a straw.
11. Before capturing the image, instruct Patient to swallow and hold,
putting the tongue to the roof of the mouth and holding for the
duration of the exposure.
