Table Alignment (Model QT-720 Only)
The Radiographic Table’s image receptor must be properly aligned with 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, tubestand/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. If the tubestand to be used provides transverse travel of the x-ray tube
relative to the table, set the tube transverse travel in the center detent position
prior to performing this alignment.
1. Position the table under the collimator, in the approximate location where it
will be mounted.
