C3 lateral view (A = asymmetric)
For
lateral views
, the patient must be standing with his/
her
face toward the front
.
(This applies to both the left-handed and the
right-handed ceph arm version).
Insert the ear plugs into the external auditory canals.
Hold the ear plug holders at their
upper ends
when
doing this.
Switching the light localizer on
using the key (28) on the Easypad.
The secondary diaphragm with the light localizer for the
reflection of the FH line moves far to the front.
When taking lateral views, the light localizer serves for
positioning the head according to the
FH
(
F
rankfort
H
or-
izontal plane). It will switch off after approx. 100 seconds
or automatically as soon as the exposure starts.
The light line roughly reflects in this area.
Have the patient tilt or raise his/her head until it is posi-
tioned correctly.
As long as the light localizer is on, a red light localizer
symbol is displayed on the touchscreen.
NOTE
i
Make sure that the light beam does not hit the patient’s
eyes (laser light).
The light localizer switches off automatically after ap-
prox. 100 seconds.
If necessary, fine-tune the head inclination using keys
(30) or (31) on the Easypad.

Slightly press and hold down the locking knob (19) while
adjusting the nose support in vertical direction to the
height of the nasal root.

Carefully push the nose support back to the nasal root.
Select the kV/mA values by touching one of the four
patient symbols on the touchscreen.
You can also choose if you want to use half the exposure
time (4.7 s Quickshot scan).
