Grids
Anti-scatter grids are used to reduce scattered radiation and improve image
quality. Grids are available as an option.
For DR Detectors focused grids are used. Focused grids require centering of
the X-ray source to the detector and a specific distance range between X-ray
source and detector. The color of the handle of the grid indicates which
distance the grid is used for.
To change the grid in the RAD Table or RAD Wall Stand:
1. Pull out the grid using the handle.
2. Store the grid in a safe place to avoid damage.
3. Insert the grid with labels facing up in the appropriate slit of the bucky.
Make sure the grid is pushed up to the end.

Caution: Using a focused grid with the X-ray source not centered
or on a wrong distance may cause reduced image quality.
Caution: Handle grids with care and store them in a safe place
when not in use. Dropping the grid can cause damage and create
visible image artifacts or reduce image quality.
Caution: If grid is not inserted completely, artifacts on the image
can be visible, e.g. of the grid edges. Push the grid all the way up
to the end.
