Anti-scatter 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 radiographic table or the radiographic 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 anti-scatter grid with the X-ray source not
centered or on a wrong distance may cause reduced image
quality.
CAUTION:
Injury of the patient or damage to the equipment can be caused
by the anti-scatter grid if it is not properly inserted in the bucky.
CAUTION:
Handle anti-scatter 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.
