10 TEMPOROMANDIBULAR JOINT EXPOSURE
All exposure values given in this section are based on
Kodak Ektavision film and Kodak Ektavision screen. If
you are using a different film and screen combination
you may have to adjust these values.
This procedure will produce open and closed views of
the left and right temporomandibular joints (TMJ) with
the Planmeca Proline XC panoramic X-ray unit.
Note that this is a double exposure and the rotating
assembly will travel through two exposure cycles.
Use the chin support for this exposure.
Select the TMJ exposure program on the Select
program type display, see section “7.2 Selecting
temporomandibular joint (TMJ) exposure program” on
page 18.
Select the correct exposure values for the patient
being X-rayed according to the values in the following
table. Note that the kV value for a TMJ exposure is
4kV higher than the corresponding panoramic
exposure.
