Checking the eccentricity of the rotation movement
The eccentricity of the rotation movement must be checked after the patient positioning mecha-
nism adjustment. This is done by comparing the distances between the line on the alignment
ruler and the x-line on the ball phantom in “0° position” and in “180° position”. If the deviation is
more than ±1 mm, the position of the sensor head should be adjusted.
Remove the sensor head from the quick connector mechanism (see instructions given in Plan-
meca Proline CC panoramic x-rays user’s manual). Attach the sensor alignment tool to the quick
connector.
Entering the 180° position:
Enter the test mode.
Press the ready key to drive the x-ray unit to the exposure position. When the unit is ready the
indicator light will come on.
Start to take a test exposure by pressing and holding down exposure button on the remote con-
trol. Stop pressing the exposure button after about 16 seconds so that the rotating unit stops
moving (near the end position).
An error code will appear on the display. Clear the error code with the CTL-key.
Manually position the rotating unit so that the center line that runs through the tube head and
sensor head is at a right angle to the wall. Slide the alignment pin through the hole in the top of
the vertical carriage so that it goes into the positioning hole in the rotating unit.
NOTE Adjust the position of the rotating unit by holding the sensor head end of the rotating unit.
Never hold the tube head when adjusting the position.
Leave the ball phantom tool in position. Place the alignment ruler in position between the primary
slot and the sensor alignment tool as described earlier.
