After the image is printed, the system will display all measured optical density
values:
The displayed values (that have to be monitored) represent the following steps on the
test film:
5
Record the density levels on Chart 1 (‘Drystar 5500/5503: Determination of
Operating Levels’). Refer to
‘Charts for general radiography QC’
on page

through
once a day for five consecutive days, as indicated on
the Drystar 5500 Chart 1.
8
Calculate the average value of the densities from the five images. These values
represent operating levels or aim values, for each density.
Operating Level
Value (Macbeth units)
(according IEC 1223-2-4
or better)
Low density
the density value of the
Low density step
0.4 ± 0.05
Mid density
the density value of the
Mid density step
1.2 ± 0.15
High density
the density value of the
High density step
2.0 ± 0.20
If the mid density value does not meet or exceeds the recommended
values, the cause must be found and the problem solved before any further
clinical films can be printed.
