Planmeca ProOne - Fine-Tuning TMJ Layer Light and Angle

11 TEMPOROMANDIBULAR JOINT EXPOSURE
User’s Manual Planmeca ProOne 51
Note that the Frankfort plane light, located on the side of
the column, can be moved up or down to accommodate
different head sizes. This is done by moving the adjusting
lever that is located next to the light slot.
The layer light will be automatically positioned at the back,
in the area of the patient’s temporomandibular joint. To
fine-adjust the position of the layer light manually, touch
and hold either of the target position arrows until the layer
light is positioned at the patient’s temporomandibular
joint.
The arrow pointing to the left moves the C-arm forward
and the arrow pointing to the right moves the C-arm
backward. The number in the target position field
indicates the position of the layer light and serves as a
reference for later retakes. The target position on the
other jaw side will change accordingly if the icon for
symmetric/asymmetric setting on the display shows an
undivided jaw (one line in the middle).
The imaging angle can be adjusted for lateral TMJ
exposures as described in section 9.3.1 “Selecting
imaging position for temporomandibular joint (TMJ)
exposures” on page 23.
Check that the Frankfort plane light and the midsagittal
plane light are still correctly positioned. Reposition them if
necessary.
NOTE
Make sure that you have selected the right patient and the
panoramic exposure mode in the Romexis program before
you take an exposure. Refer to the Romexis User’s
Manual.
NOTE
Images can be saved on a USB memory stick instead of
the computer. Refer to section 14.2.6 “Imaging without PC
(P2600)” on page 96 for more information.
