Panoramic beam width
If the X-ray beam is too wide, i.e. it exceeds the borders of the rectangle marked on the align-
ment tool, or if it is too narrow, the width of the beam must be adjusted. The beam width on
the beam alignment tool should be approx. 4mm (0.16 in.).
Adjust the width value of the primary collimator with the X-Pan collimator width arrow
fields and drive the primary collimator to the selected width by touching the Test field.
Use the 0.6mm feeler to check the width of the opening between the collimator blades as
shown on the Fig. 18 below. The number on the display should be approx. 68 when the open-
ing is 0.6mm.

If necessary, repeat the procedure.
Accept the new position and width and exit the Pan X-collimator calibration mode by touching
the Done field.
