11 TEMPOROMANDIBULAR JOINT EXPOSURE
User’s Manual Planmeca ProOne 49
Always try to minimize the radiation dose to the patient.
Touch the C-arm return button to move the C-arm to the
patient entry position if it is not already there.
Alternatively, you can touch either of the target position
arrows to move the C-arm to the patient entry position.
You can set the X-ray unit so that the C-arm will
automatically return to the patient entry position at the end
of an exposure cycle. Refer to section 14.2.3 “Functions
after exposure (P2300)” on page 86 for more information.
Touch the temple support button to open the temple
supports if they are not already open.
Guide the patient to the unit so that they are facing the
chin support. Explain to the patient that you will take a
double exposure and that the unit will rotate twice.
To adjust the height of the unit, press either of the height
adjusting buttons on the display until the opening in the
chin support is approximately level with the patient’s
mouth.
The unit moves slowly at first, then faster.
