coincides with the midsagittal plane light beam.
Midsagittal
plane light
Position the patient's head so that the Frankfort plane is
tilted down five degrees. To do this support the back of
the patient's head with your hand and, using the Frankfort
plane light as a reference line, adjust the position of the
patient's head by raising or lowering the unit with the
height adjusting buttons. Make sure the patient's back is
straight.
The Frankfort plane light, which is located on the side of
the column, can be moved up or down. This is done by
rotating the thumb wheel that is below the light slot.
