3.
Insert the cassette support bracket into the appropriate holes.
4.
Insert the cassette between the cassette clamps, resting it on the cassette
support bracket, then reposition the clamps against the cassette and close the
cassette-clamp locking assembly.
5.
Push the cassette tray back into the Bucky.
NOTE:
To prevent damage to the cassette-clamp locking assembly always close it
prior to inserting (pushing) the cassette tray into the Bucky.
NOTE:
Normally the cassette tray does not have to be completely removed from the
Bucky in order to load a cassette. Cassettes may be inserted in the tray by
pulling the tray until movement is stopped by the catch on the lower rear of the
tray.
However, if it is desired to remove the tray from the Bucky, pull the tray out until it
is stopped by the catch, then press the catch against the tray bottom and hold it
while sliding the tray out.
NOTE:
When equipped with a cassette-size-sensing tray the SG–100 supports auto-
matic collimation. The tray must be inserted all the way into the Bucky to
implement automatic collimation. If the tray is not inserted all the way into the
Bucky, the collimator will not switch to automatic collimation.
NOTE:
Use caution to prevent deformation of the cassette sensing arm. Its angular
shape is important in obtaining accurate field placement. If the arm is bent it
must be replaced. Attempts should not be made to straighten the sensing arm
if it has been bent or deformed.
3-9Cassette Removal
3-10Manual Cassette Tray
To remove a cassette from the manual cassette tray, pull the tray out fully by its
handle. Pull up on the tightening lever and pull it back away from the cassette.
The cassette is now free to be removed.
3-11AEC Detector Areas
The SG–100 Vertical Bucky Stand supports an Ion Chamber Detector. Complete
operating details for the Ion Chamber Detector are given in the generator operat-
ing manual or automatic exposure control operating manual.
The three field pattern on the front panel of the SG–100 Vertical Bucky Stand
matches to the three sensing areas of the Ion Chamber Detector.
3-12Alignment
It is important that the X-ray tube unit be transversely centered accurately with the
center of the Bucky. Density cutoff at the edges of the film and appearance of grid
patterns indicate inaccurate transverse alignment. With an anti-diffusion grid verti-
