CBCT ACQUISITION
6.1 SELECTING THE EXAM TYPE
· From the AIS tool bar press the CBCT button to enter in the acquisition window.
· From the acquisition window (refer to AIS Operator’s manual for the description of the acquisition window) select the patient
type (man, woman, child) and size (small, medium, large).
· Select the sector of the exam (dental, nose, ear), the dimension of the FOV and the quality of the image, then check the
predened loading factors.
FOV selection
The size of the FOV describes the scan volume of CBCT exam. That volume determines the extent of anatomy included.
CAUTION
To the extent practical, FOV should only slightly exceed the dimensions of the anatomy of interest.
For most endodontic applications limited FOV CBCT is preferred to medium or large FOV CBCT because there is less radiation dose to
the patient, higher spatial resolution and shorter volumes to be interpreted.
