Radiation beam too far to the right or left
WARNING
WARNING: DO NOT ADJUST THE POSITION OF THE PRIMARY SLOT MECHANISM WHILE
X-RAYS ARE BEING GENERATED. CHECK THE BEAM POSITION, ADJUST THE POSITION
WITH THE X-RAYS SWITCHED OFF AND THEN RECHECK THE POSITION. IF THE BEAM IS
STILL MISALIGNED REPEAT THE OPERATION.
NOTE The ceph primary slots are also adjusted according to instructions given in this section.
If any of the beams are too far to the left or right of the alignment rectangle they must be cen-
tered.
Figure 10
NOTE A microprocessor controlled motor determines the position of each slot. If the beam is
readjusted to the left or right the new position must be reprogrammed into the memory.
Enter the service mode if you are not already in it.
Press the CTL-key.
Press and hold down the primary slot key until the number of the slot that you are checking
appears on the primary slot display and starts to flash. You are now in the primary slot calibration
mode.
For example, if you have just checked the position of the beam from the slot number 1, the
number 1 will appear on the display.
Adjust the position of the beam by pressing the patient positioning (mm) keys. The minus key will
move the slot mechanism, and beam to the left, and the plus key will move the slot mechanism,
and beam to the right.
Check the position of the beam again and, if necessary, repeat the above alignment procedure
until the beam is within the alignment rectangle on the fluorescent screen.
CAUTION Radiation is generated when the exposure button is pressed. Take adequate protection
measures. Keep the exposure time as short as possible.
