10 PANORAMIC EXPOSURE
This procedure will produce a full size panoramic
exposure of both jaws.
If the optional segmenting function is activated on your
X-ray unit, you can take a partial exposure by selecting
only certain vertical or horizontal segments of the jaw,
refer to section 9.2.1 “Selecting exposure area for
panoramic exposures (optional)” on page 19.
Use a bite piece for this procedure. Insert the chin rest
and a bite piece into the adapter on the patient support
table.
For edentulous patients or for patients who are unable to
use the bite piece you can use the chin cup or the chin
support. You may have to place a roll of gauze or cotton
between the patient’s jaws to raise the upper ridge to the
correct position.
We recommend that you use the chin support when taking
bitewing exposures.
We recommend that you use the bite piece when taking
exposures with the Autofocus function (AF ON).
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 panoramic program you require, refer to
section 9.2 “Selecting panoramic exposure program” on
page 15. Select the patient size as described in section
9.7 “Selecting patient size” on page 34.
