e. Slowly roll the Receptor Cabinet along the bearing rails while checking
for smoothness. The mounting holes on the Receptor Bearing Brackets
are slotted to provide adjustment. Adjust the brackets as required until
receptor travel is satisfactory (smooth and even through full travel),
then fully tighten all bracket screws.
f. Check operation of Receptor Cabinet Lock Release Lever; in locked
(down) position, cabinet should remain firmly in place. When unlocked
(lever up), cabinet should be able to move freely. If necessary, adjust
Receptor Cabinet Lock Release Lever (refer to Receptor Cabinet Lock
Release Lever Adjustment procedure in Chapter 5, Maintenance).
g. On systems equipped with moving grid bucky, route the bucky cable
through the back of Table Base and up through the Table Top Frame.
Provide a service loop in cable such that there is no cable interference
at any point throughout the full travel of Receptor Cabinet. Connect
#10AWG yellow/green ground wire between table ground stud (on rear
side of Table Base) and the x-ray generator.
TABLE ALIGNMENT
The Radiographic Table’s image receptor must be properly aligned to the pro-
jected light field of the collimator in order to attain accurate x-ray exposures.
This procedure may require slight repositioning of the table base, which may
affect the position or arrangement of the leveling shims, requiring an additional
check prior to final table mounting. Collimator calibration, tube stand/collimator
alignments, and collimator light field to x-ray field adjustments, as described in
their respective manuals, must be completed prior to performing this proce-
dure.
