AEC RESET
: If the exposure is aborted by the AEC back-up timer, the indicator
on the “
AEC Reset
” push-button blinks accompanied of an audible alarm. Next
exposure is inhibited until the AEC function is reset by pressing the “
AEC Reset
”
push-button. When the Generator is in
“Prep”
mode, the AEC function can not
be reset.
The “
AEC Reset
” push-button may blink when the kVp value, AEC Density and
Film / Screen Combination select a technique that is out of the operative range
with AEC, it inhibits the next exposure. Change any parameter (kVp value, AEC
Density or Film / Screen Combination) in order to obtain a technique enabled
for AEC.

ANATOMICAL PROGRAMMER (APR)
Anatomical Programmer (APR) module is comprised of the controls which
select the Patient Size and Display Selectors. The process is shown on the APR
Display.
The APR techniques are factory pre-programmed according to different
standard technique sets in a X-Y matrix format that combines eight Body
Regions (Y-axis) with eight Anatomical Views (X-axis). Besides the
radiographic parameters, selections of the workstation or AEC (density, fields
and film / screen combination) can be assigned to the APR techniques. These
selections will be always common for all the patient sizes of each Anatomical
View. These techniques may be modified and stored anew into non-volatile
memory by the operator.
The APR techniques are intended as a guide line only. Accurate exposure
factors are dependent among other things on Bucky grid factors, table top
absorption, screen film combinations and film processing.
The APR is activated when one of the three Patient Size (small, medium or large
size) is selected (push-button lighted), and it is deactivated when all of them are
deselected.
APR language may be changed, just after selecting one of the
patient size (APR activation), pressing the “Power ON”
push-button. Language selected remains stored even after the
equipment is turned Off. (Only for Generators equipped with this
option).
If an APR technique is to be stored with AEC parameters, a
suitable back-up time (and/or mAs) MUST be stored in the
programme by the operator.
