User’s Manual Planmeca ProMax Cephalostat 1
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 software version 3.8.0.0.r or later.
This software version is compatible with Planmeca
Romexis software version 4.5.0.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.
2 SWITCHING X-RAY UNIT ON
The on / off switch is located on the underside of the
stationary column top.
NOTE
To prolong the lifetime of your X-ray unit, always switch the
X-ray unit off when it is not in active use.

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.
3.4 Emergency stop button
The emergency stop button is located on the top of the
stationary column. Press the button to stop the X-ray unit
operating in an emergency. When the emergency stop
button is pressed down, all movements of the X-ray unit
are blocked and the unit will not generate radiation. The
up / down movement 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.

4.5 Preparing patient
Ask the patient to remove any spectacles, hearing aids,
dentures, hairpins, and personal jewellery such as

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.
