Brief Solution
Solution Steps
Full leg full spine images are cropped to the collimation
area that is automatically detected by NX. The cropping
is intended to remove non relevant areas of the image.
Nevertheless it can occur that the cropping makes useful
diagnostic information invisible. In this case you must be
able to turn black border and cropping off or re-colli-
mate the image manually.
Failing auto collimation.
This problem is solved by:
• Turning off the black border and cropping on the
stitched image.
