5 PATIENT POSITIONING LIGHTS
5.1 Checking the lights
The positions of the light beams from the two patient positioning lights should be checked.
Place the Frankfort plane alignment tool into position on top of the ball phantom.
Figure 65
Press either of the patient positioning keys to switch the positioning lights on and then a sec-
ond time to drive the patient positioning mechanism to 00 if it is not already there.
The Frankfort plane light beam should be located between the two black lines on the align-
ment tool. It should be horizontal.
Figure 66
The focal trough positioning light beam should be positioned so that it is on the black refer-
ence line on the side of the ball phantom.
Figure 67
If the light beams do not coincide with the black lines or they are not in focus, they should be
adjusted.
