TEMPOROMANDIBULAR JOINT (TMJ) EXPOSURE
This exposure will produce closed and open views of the
left and right temporomandibular joints.
NOTE You can set the X-ray unit so that the imaging position
will be automatically moved forwards for the open jaw
exposure (information display i27.1).
Insert the chin support into the adapter. Insert the adapter
into the holes in the patient support table.
Select the double TMJ program you wish to use (see
section 5.4 "Selecting temporomandibular joint (TMJ)
program" on page 22).
Select the patient size (see section 5.2.1 "Selecting
patient size" on page 15).
Select the image position parameters (target position,
imaging angle, symmetric / asymmetric setting, left / right
side exposure) as described in sections 5.4.1 "Selecting
jaw size and adjusting imaging position & angle in TMJ
programs" on page 23 and 5.4.2 "Selecting jaw side in
double TMJ programs" on page 24.
The exposure values will automatically change to
correspond with the selected exposure program and
patient size. The preset exposure values are shown in the
following tables. The preset exposure values are average
values and they are only meant to guide the user. If
necessary, you can change the preset values as
described in section 5.2.2 "Selecting kilovolt and
milliampere values" on page 15.
NOTE Always try to minimize the radiation dose to the
patient.
