OLLIMATOR
Ralco guarantees the correct collimator functionality, format compliance and light/X-Ray field
alignment only if the mounting flange and the collimator have been installed exactly in the
centre of the X-Ray beam.
All Ralco collimators are aligned on our test bench utilizing specific references/values for our
X-Ray tube focus, detector and Source to Image Detector Distance (SID). The customer must
know and verify all known variables which may influence the X-Ray tube focus and collimator
alignment. These may include, the X-Ray tube focus position tolerance, distance from X-Ray
tube focus to collimator mounting plane, or the SID.
