Installation Manual ORTHOPHOS XG 3D / Ceph

Pan diaphragm
13.2.1.2.1
Automatic adjustment: Pan diaphragm (standard)
✔
The OP XG needle phantom is
not
in the pan bite block holder on the
unit.
1. In the structure tree, under
"2D Adjustment"
, click on the
"Pan -
Diaphragm"
element (S030.2).
The
"Pan - Diaphragm"
menu is displayed in the action area. The
menu supports precision adjustment and coarse adjustment
(precision adjustment is pre-selected). Perform a precision
adjustment first. In most cases, previous coarse adjustment is not
necessary.
2. Make SIDEXIS XG ready for exposure. [ → 206]
3. Take an exposure (60 kV / 3 mA; 0.2 s) [ → 206].
SIDEXIS XG Calculates the adjustment values Sx and Sy
automatically from the exposure and enters them in the text
boxes of the
"Pan - Diaphragm"
menu.
The exposure is displayed in the exposure window in SIDEXIS
XG.
IMPORTANT
If a message window indicating that the diaphragm is tilted appears in
the menu during adjustment
"Pan - Diaphragm"
, the primary diaphragm
is mechanically maladjusted in the vertical axis. In this case you must
take the exposure again.
IMPORTANT
If a message window indicating that another X-ray has to be taken
appears in the menu during adjustment
"Pan - Diaphragm"
, repeat the
procedure starting at Step 2, even if the values in the menu's text boxes
are equal to zero. This additional exposure ensures that the diaphragm
gap width offset is also adjusted correctly.
