Acquisitioning (Scanning)
6-7
time (reducing chance of movement), at a reduced radiation
dose, with a Voxel Size that maximizes detail without the dataset
being too large.
It is recommended to use a faster Scan Time (for example, 5
sec.) for children, some elderly Patients (if movement is a
significant issue), or if you require only a quick pan or TMJ
Scan, or a secondary/follow-up scan (e.g. Open Jaw TMJ views,
TMJ views with appliance/splint, etc.). Since it is a faster Scan
Time, the radiation dose is the lowest, and the opportunity for
Patient movement is less.
6. Adjust the Volume Center slide control to select the position of
the x-ray sensor (front to back).
7. Select the Height of Reconstructed Volume from the drop-
down list to indicate the portrait or landscape position of the x-
ray sensor.
8. Once the settings are made, you may perform a Preview , Dry
Run , and Capture scan.
Preview, Dry Run, and Capture Scans
After the acquisition is launched and the protocol is selected, a
Preview of the Patient is recommended to verify Patient positioning.
WARNING
The X-ray unit may be dangerous to the Patient and operator if you
do not observe and follow the safe exposure factors and operating
instructions. Do not operate this system unless you have received
training to perform a procedure.
1. Click the Preview button under Exposure .
