Step Action
3.
Open up the collimator to expose all three fields of the AEC pickup. Ensure that the central ray remains centered relative to the
image receptor.
4.
Place the absorber (with thickness selected for 75 kV per table 3D-8) in the X-ray field, ensuring that the radiation is COMPLETELY
blocked by the absorber.

Ensure that in the
RECEPTOR SETUP
menu, each receptor has the desired AEC
channel assigned to it. Refer to
RECEPTOR SETUP
in chapter 3C.
Ensure that in the
Receptor Setup
window, each receptor has the desired
AEC channel assigned to it. Refer to
RECEPTOR SETUP
in chapter 3C.

6.
In the
RECEPTOR SETUP
menu, set
MEMORY
to
NO
for each image receptor.
This will ensure that the next receptor
being calibrated will not remember the
techniques from the previous receptor.
The
MEMORY
function may be reset as
desired after AEC calibration is completed.
In the
Receptor Setup
window, under the
Receptor Properties
tab, set
Memory
to
off
for each image receptor. This will
ensure that the next receptor being
calibrated will not remember the
techniques from the previous receptor.
The
Memory
function may be reset as
desired after AEC calibration is completed.
In the
Receptor Setup
window, under
the
Receptor Properties

The
Memory
function may be reset as
desired after AEC calibration is
completed.
7.
In the
RECEPTOR SETUP
menu, ensure
that the
AEC BACKUP MAS
and
AEC
BACKUP MS
are set sufficiently high that
the generator backup timer will not
terminate the exposure.
In the
Receptor Setup
window, under the
AEC
tab, ensure that the
AEC Back-Up
mAs
and
AEC Back-Up ms
are set
sufficiently high that the generator backup
timer will not terminate the exposure
In the
