WARNING: When performing the
operational check, keep the collimator
covered with the lead cap.
PREPARING THE FILM
When the X-ray machine is operational, prepare
the panoramic film. Load the film into a cassette drum,
label it, and then mount it in the cassette drum
assembly on the X-ray machine. To load and mount the
cassette drum, follow the manufacturer's instructions.
LABELING THE CASSETTE
The cassette is labeled for the purposes of
orientation and patient identification.
To properly orient the finished radiograph so
you can distinguish the left from the right side of the
patient's dentition, tape a lead letter "R" in the
lower right-hand corner on the outside of the
cassette cover.
There are two ways to label the cassette for patient
identification. You can use a self-adhesive label or an
X-ray film identification printer. Follow the
manufacturer's instructions when using the printer.
The patient information includes: the patient's name
(last name, first name, and middle initial), family
member prefix code, social security number, and the
date of the exposure.
REQUIREMENTS FOR A GOOD
PANORAMIC RESULT
Follow the manufacturer's operating instructions
for complete operation of the panoramic X-ray
machine before you attempt to use it. The following is
a list of important procedures that must be followed to
ensure a good quality X-ray is produced.
as stra
Make sure patient's back and cervical spine are
ight as possible.
Check that the patient's mid-sagittal plane is
centered within the unit.
Ensure the patient's frankfurt plane is horizontal.
Check that the anterior maxillary and
mandibular teeth are located on the indents of the bite-
block. If the patient's bite is abnormal, adjust mandible
forward or backward to compensate.
Observe patient to assure there is no movement
during the radiographic procedure.
OPERATING THE PANORAMIC-RAY
MACHINE
With the machine operational and the film cassette
drum in the cassette drum assembly, you are now ready
to take the radiograph on the patient. Follow the
manufacturer's instructions for patient positioning and
operation. When the patient is positioned, explain the
exposure procedures. Then make the exposure and
process the film. You must wait 5 minutes between
exposures to prevent overheating of the X-ray head.
USER MAINTENANCE
The panoramic X-ray machine requires very little
user maintenance. Wipe the metal and painted parts
with a soft, dry cloth daily.
Never attempt to repair the panoramic X-ray
machine yourself. Report malfunctions to your
supervisor. All repairs are the responsibility of the
dental equipment repair technician.
