Planmeca ProMax User's manual

1 Introduction
This manual describes how to operate the Planmeca ProMax Cephalostat.
The Planmeca ProMax Cephalostat is used to position the patient’s head
accurately for taking X-ray images of the skull. The device can also be used
for taking hand images for bone age studies.
The cephalostat is attached to a 2D or 3D Planmeca ProMax X-ray unit. The
X-ray unit has a separate manual. Refer to the User’s Manual of the X-ray
unit for any general information about the X-ray unit.
NOTE
This manual is valid for Planmeca ProMax software version 3.9.6 or later.
This software version is compatible with Planmeca Romexis software
version 5.2.1.R or later. To check the software version of your X-ray unit,
select Settings > About > 4100 Component Information > ProMax SW
version.
Make sure that you are fully acquainted with the appropriate radiation
protection measures and these instructions before you use the X-ray unit.
NOTE
The X-ray unit may be used by health care professionals only.

3. Positioning cones
4. Nasal positioner
5. Hand imaging support
3.3 Patient positioning controls
The patient positioning controls are located above the touch screen.
The up and down buttons are used to adjust the cephalostat to suit the
height of the patient.
The cephalostat moves slowly at first, then faster.
NOTE
If for some reason either of the buttons gets stuck during operation, you can
stop the up / down movement by pressing any of the other control buttons or
the positioning joystick. This is a safety measure that guarantees that the
up / down movement can be stopped in an emergency.

There is an additional height adjusting button on the underside of the
cephalostat. The cephalostat moves up or down depending on which side
the button is pressed.
NOTE
Be careful that the X-ray unit does not hit the ceiling when you press the up
button. The maximum height can be adjusted to suit offices with a low
ceiling, contact your service technician for help.
NOTE
Make sure that there is no object under the X-ray unit when you press the
down button. If something is in danger of becoming trapped, release the
button immediately to stop the movement. Clear any obstruction before
pressing the button again.
NOTE
The column movement stops automatically if the emergency stop plate at
the bottom is pressed upwards. Clear any obstruction before moving the
column again.
NOTE
When positioning seated patients (e.g. in a wheelchair) always first move the
cephalostat down before you position the patient.

will stop within a distance of 10 mm (0.4 in.).
A help message will appear on the touch screen. Guide the patient away
from the X-ray unit. Then release the emergency stop button. The X-ray unit
will automatically restart.

4 Preparations for exposure
4.1 Preparing X-ray unit
4.1.1 Attaching cephalometric patient supports
The ear posts are marked with the letter L for the patient’s left ear and letter
R for the patient’s right ear.
The positioning cones contain small metal objects that are visible in the
image. They help you to identify the patient’s left and right side.
• The left ear post contains a ball.
• The right ear post contains a ring.
NOTE
Ensure that you position the ear posts the right way round.

4.2 Additional preparations on X-ray units with Dimax sensor
If a Dimax sensor is attached to the C-arm, the sensor must be moved to the
cephalostat before you can take cephalometric exposures.
1. Remove Dimax sensor from
C-arm (see section "Removing
sensor from C-arm" on page
10)
2. Attach Dimax sensor to
cephalostat (see section
"Attaching Dimax sensor to
cephalostat" on page 13)

sensor from the C-arm before you can take cephalometric exposures.
1. Non-rotating tube head:
Remove 3D sensor from C-arm
(refer to section "Removing
sensor from C-arm" on page
10)
2. Rotating tube head: No need
to remove 3D sensor
3. No joint: Tube head does not
rotate

4.4 Preparing Planmeca Romexis
First select the patient.
4 Preparations for exposure
User's manual Planmeca ProMax 15

Then select the cephalometric exposure.
Refer to the Planmeca Romexis User’s Manual for details on Romexis
functions.
4.5 Preparing patient
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 arm structures of the X-ray unit.
Place a protective lead apron over the patient’s back if required.
NOTE
We recommend that you image patients with poor health in a sitting position.
