2.
Make a MAG2 mode Fluoro exposure. Using the scale on the beam alignment tool, measure and record the X and Y diameters
(X
Fluoro
and Y
Fluoro
) displayed within the digital mask on the Workstation.
3.
Calculate and record the absolute value of the difference between the film and Workstation X axis values (X
Film
– X
Fluoro
=
X
Diff
). Verify that the difference recorded is less than 28 mm (3% SID).
4.
Calculate and record the absolute value of the difference between the film and Workstation Y axis values (Y
Film
– Y
Fluoro
=
Y
Diff
). Verify that the difference recorded is less than 28 mm (3% SID).
5.
Calculate and record the sum of the values in Steps 3 and 4 (X
Diff
+ Y
Diff
= Sum). Verify that the sum is less than or equal to 36
mm (4% SID).
Pass or Fail
If the measurements recorded for each field size (50 mm x 50 mm, NORM, MAG1 and MAG2) are within the limits specified,
indicate in the
Report/Checklist
that the Beam Alignment Test passed. If it passed, continue with the Installation Procedure.
If the measurements recorded for each field size are not within the limits specified, indicate in the
Report/Checklist
that the Beam
Alignment Test failed. If it failed, perform the beam alignment procedure contained in the 9800 C-Arm Service Manual.
