Assemble and attach Receptor Alignment Tool
(RAT) to collimator using RAT holding fixture.
Using collimator light, note and record where
edges of light field appear on RAT grid pattern.
Expose and develop film (recommend 4 MAS
at 50 KVP for par speed film with medium
screens at 40” (1.016 m) and 16 MAS at 72”).
(1.83 m) |
Measure x-ray image length and width. Each must
agree with numerical indicator settings (step 2)
wizhin 1.8% of SID. (.72” at 40” SID, (18.3 mm at
1.016 m) on 1.3” at 72” SID) (33 mm at 1.83 m).
Mark light field (step 4) in relation to x-ray field
on film. Measure misalignment at each of the
four edges. Total misalignment of either the two
length of two width edges must not exceed 1.8%
of SID.
Repeat Steps 1 through 7 for a SID of 72” (1.83 m).
If edge to edge light field and x-ray field alignment
exceeds 1.8% of SID adjust as follows:
a. Remove the Blade Control Knobs and
collimator front nameplate. Refer to
Section 14-1.
b. With nameplate removed, temporarily
reinstall knobs and adjust field size to
same setting as in step 2.
c. Slightly loosen the two light housing
mounting screws. See Illustration
d. With RAT in holding fixture beneath
collimator, shift light housing so that tight
field aligns with the grid pattern of the
x-ray field from Step 5.
