Alignment Device
This device is used to ensure the collimator
mounting flange is correctly aligned to the X-ray
beam. The X-ray tube manufacturer provides a
tolerance for the placement of X-ray tube focus.
Ralco recommends to use the Focal Alignment
Device (jig) to ensure the correct flange alignment
with the centre of the X-Ray beam, see
Fig. Focal
Alignment Device.
By making an exposure, it is
possible to verify the perpendicularity and
concentricity using fixed references on the X-Ray
image.
Once the mounting flange is aligned the collimator
light/X-ray field should also be aligned (within
specific tolerances).
Please consult the technical specifications of your X-
Ray tube to find the maximum tolerance for the
position of the focus. Should the use of an alignment
device not be possible, Ralco collimators allow for
the regulation of the light field.
