5-2 Bucky Centering Light Check and Adjustment
The Bucky centering light is factory adjusted to provide a projected crosshair image in front of the
collimator in line with the transverse centerline of the right field. If the Bucky centering light is to be
used, check the settings.
1. Adjust the biades to yield an approximate 12” x 12” (304.8 mm x 304.8 mm) field size.
2. Establish a transverse guide line-approximately 20” (0.5 m) length on a surface of 40” (1.016 m) SID.
3. Energize the field light. Position the tube unit and collimator so the shadow of the transverse
crosshair fails on the transverse guide line.
If the Bucky light crosshair shadow does not center within 1/4” (6.35 mm) of the guide line and is not
reasonably parallel to the line, adjust per the following steps.
4. Remove the blade control knobs and the nameplate per instruction in Sec. 4-1 of this chapter.
CAUTION: BECAUSE OF THE HIGH ENERGY LAMP, THE LIGHT HOUSING MAY BE HOT.
5. Slightly loosen the two socket head screws on the bottom of the light housing.
6. Slide the entire Bucky light lens assembly until the proper position is obtained.
7. Re-tighten the screws.
8 If necessary, rotate the light housing to move the Bucky light field. !f this is done, recheck the
position of the light field and the shadow crosshairs per instructions in Sections 4-1 and 6.
9. Replace the nameplate and the blade control knobs and repeat steps 1 through 3.
53 Extension Cylinder Alignment Check (Optional Accessory)
1. Position the tube unit and collimator perpendicularly over a smooth surface such as a tile floor.
Using the collimator measuring tape, set the SID at 40” (1.016 т).
2. Slide the extension cylinder into the tracks at the bottom of the collimator until the cylinder latch
snaps into the slot on the right-hand track.
3. Darken the room and energize the field light.
The illuminated area on the cassette should show egual sectors of light on either side of the crosshair
shadows.
4. | If adjustment is necessary, proceed as follows:
a Loosen the eight cone track screws.
b. Shift and/or shim the tracks as necessary.
c. Re-tighten the screws.
d. Re-check the alignment.
