Chapter D - ADJUSTMENT & CALIBRATION
From the list of Service settings select Primary collimator.
Figure 15
The display shown below appears. The number above the arrow fields indicates the collima-
tor number and the collimator is changed with the Next field. Select collimator number 0.
The radiation beam from the collimator number 0 can now be checked without the rotating
unit moving.
Darken the room sufficiently so that you will be able to see the image of the radiation beam on
the alignment tool (it is fluorescent and will glow when the radiation beam strikes it), but not so
dark that you cannot see the borders of the alignment rectangle.
Protect yourself from radiation and press the exposure button. The beam image will appear
on the alignment tool. Observe the beam from behind the tube head.
CAUTION Radiation is generated when the exposure button is pressed. Take adequate protection
measures. Keep the exposure time as short as possible.
