Establishing the image geometry reference values
for general radiography applications (DT 2 B and
DT 2 C)
Procedure
1 Print the QC test image or use the previously printed test image.
For an example, see
DT 2 C)" on page 90.
2 To determine the reference values for geometry, measure the distances
A and B of the geometric square on the test image.
3 Record these values as reference dimensions Aref and Bref on Chart 4
('Drystar AXYS Geometric Consistency Control Chart'). Refer to
trol Charts" on page 149.
These charts will be used for the annual quality test. For more information, refer to
"Performing the Annual QC tests for general radiography applications (DT 2 B and
DT 2 C)" on page 103.

WARNING: Make sure to measure distance A from the left edge of
the left line to the right edge of the right line and distance B from
the upper edge of the upper line to the lower edge of the lower
line.
WARNING: We strongly recommend using a 30 cm (12-inch)
machinist scale with 0.5 mm divisions (1/64 inch).
