12 SINUS EXPOSURE
This procedure will produce an exposure of the maxillary
sinus along the selected plane.
Use the chin support for this exposure. Insert the chin
support into the adapter on the patient support table.
Ask the patient to remove any spectacles, hearing aids,
dentures, hairpins, and personal jewellery such as
earrings, necklaces and piercings as these can produce
shadows or reflections in the image. The patient should
also remove any loose items of clothing (e.g. scarf, tie)
that might get caught in the unit’s arm structures.
Place a protective lead apron over the patient’s back if
required.
Select the sinus program you require, refer to section 9.4
“Selecting sinus exposure program” on page 25. Select
the patient size as described in section 9.7 “Selecting
patient size” on page 34.
Select the imaging position or side as described in section
9.4.1 “Selecting imaging position for sinus exposures” on
page 27.
The exposure values will automatically change according
to the selected patient size. The preset exposure values
are shown in the following table. The preset exposure
values are average values and they are only meant to
guide the user. If needed, you can change the preset
values as described in section 9.8 “Selecting kilovolt and
milliampere values” on page 35.
Always try to minimize the radiation dose to the patient.
