16. MAG 1 field
—
Calculate and record the absolute value of the difference between the film and
Workstation Y axis values as follows: Y1 =
|
Y
Step 13
-
Y
Step 14
|
Verify the difference is less than 28 mm (3% SID).
Write the Y1 value on the form.
17. MAG 1 field
—
Calculate and record the sum of X1 and Y1 as follows: Sum1 = X1 + Y1.
Verify the sum is less than or equal to 36 mm (4% SID).
Write the Sum1 value on the form.
18. Using the film, measure and record and
MAG 2
field X and Y exposure diameters. If a stop sign
pattern is displayed, refer to preceding step to determine how to make the measurement.
19. Make a
MAG 2
mode fluoro exposure. Using the scale on the alignment tool, measure and record
the X and Y diameters displayed within the digital mask on the Workstation.
20. MAG 2 field
—
Calculate and record the absolute value of the difference between the film and
Workstation X axis values as follows: X2 =
|
X
Step 18
-
X
Step 19
|
Verify the difference is less than 28 mm (3% SID).
Write the X2 value on the form.
21. MAG 2 field
—
Calculate and record the absolute value of the difference between the film and
Workstation Y axis values as follows: Y2 =
|
Y
Step 18
-
Y
Step 19
|
Verify the difference is less than 28 mm (3% SID).
Write the Y2 value on the form.
22. MAG 2 field
—
Calculate and record the sum of X2 and Y2 as follows: Sum2 = X2 + Y2.
Verify the sum is less than or equal to 36 mm (4% SID).
Write the Sum2 value on the form.
23. Using the film taken in steps 1 - 6 and ruler, verify the center of the image is centered on the sheet of
film
—
(X Y offset) is less than 16 mm (13/16
″
)
—
2% SID.
Write this value on the form as CENTER.
24. If all of the previous steps pass successfully record the results on the PM form and then continue
with the next procedure. Otherwise perform the Beam Alignment procedure contained in the 9600
System Service Manual. If beam alignment could not be tested, record why it could not be done on
the PM form.
