Chapter D - ADJUSTMENT & CALIBRATION
Select kilovolt and milliampere values high enough to enable the radiation beam to be seen in
a darkened room for example 62kV and 6mA. The actual values will depend on how dark the
room is.
Stand behind the tubehead and protect yourself from radiation. Press and hold down the
exposure button. The image of the radiation beam from slot number 4 will appear on the
alignment tool.
The radiation beam must appear within borders of the rectangle marked on the beam align-
ment tool and to the right of the line marked "Soft tissue filter 0mm".
Figure 42
If the left-hand side of the radiation beam does not reach the line marked "Soft tissue filter
0mm" or extends passed the line the soft tissue filter is in the wrong position it must be repo-
sitioned. Refer to the section "Soft tissue filter adjustment" on page D-39.
