• Place a 35x43 cm. (14x17") cassette on the table top or other flat, horizontal surface.
• Position the  x-ray tube/collimator assembly with the focal spot at 1 meter (40") over the 

cassette with the x-ray beam perpendicular to the cassete surface.   Do not use measure-
ment indicators on the system as reference values, but measure the distance from the 
focal spot to the cassette surface.

If  the x-ray beam cannot be positioned vertically use  clamps, masking tape, or other material 
as required, to position the x-ray tube and image receptor. The x-ray tube and the image 
receptor must be set out at the specified FFD/SID distance perpendicularly to the x-ray tube as 
described in the following procedure.

• Use the collimator light to centre the cassette in the field. 
• Mark the location of the cassette with masking tape 

or other means so that it may be removed and 
replaced in the same position. 

• Place white paper on top of the cassette to provide 

maximum contrast for the light field. 

• Set the collimator to provide a field size of 30x30 cm. 

(14x14") at one meter (40").

• Activate the light field and use it to position 18 coins 

as shown in the diagram. 

• Position each pair of coins touching one another so 

that the inner coin is lighted as much as possible and 
the outer coin is lighted as little as possible. 

• The points where the coins contact  will define the 

edges of the light field.

• The extra two coins are to be set: 

• one in a corner to ascertain film position. 
• the other at the instersection of the diagonals to define film centre.

• Set the  x-ray generator to produce a density of about  50 kVp, 5 mAs.
• Make an exposure. 
• Remove the cassette and process the film. 
• Use the test film to check the alignments described below.
