STORED ENERGY SE GENERATORS

Quantum’s advanced Stored Energy (SE) technology permits
powerful operation using only a standard “low amperage” wall
outlet or alternate power source. The SE’s
power cells are virtually maintenance-free
and provide years of usage. These units are
ideal in facilities where incoming power
is unavailable and for mobile imaging
applications. (50kW to 20kW)

GENERATOR OPERATING MODES

The QUEST HF Series enables users to select from three main
operating modes (3 point, 2 point or 1 point), offering great
versatility for pre-programmed or customized imaging.

ANATOMICAL PROGRAMMED RADIOGRAPHY APR

Accessing a menu with over 100 examination views derived from 10
anatomical regions, the APR mode automatically determines and sets
the required technique factors. These parameters include kVp, mA, time
(mAs), focal spot, film speed, SID and imaging receptor. In addition, the
operator may input the actual patient thickness (in cm’s) providing the
optimal technique parameters for that exam. Each individual examination
view provides up to 50 different technique factors, depending upon the
size of the patient, for up to 5000 total anatomical programs.

APR/AEC MODE

The APR mode, when used in cooperation with AEC, provides
superb uniformity of images and virtually eliminates the need
for retakes. The AEC ionization chamber control will
automatically terminate the exposure at the precise interval
needed for the optimal density of the film.

APR/PATIENT TYPE MODE

The Patient Mode is prompted when APR is used without an
AEC function. This innovative feature permits the operator to
change the mAs (time) to accommodate for differences in
actual patient densities. A quick key, controlling increments of
+/- 25% or 50%, permits rapid adjustment from the patient
type defined as “average.”

AUTOMATIC EXPOSURE CONTROL AEC MODE

The dedicated AEC mode provides exceptional uniformity and image
consistency through the automatic termination of exposure at the precise
mAs required for a perfect film. The system also provides an 11-step
selection of AEC density (in 15% increments) for complete operator
control. The operator may choose from various film speed combinations.

MANUAL MODE

The Manual Mode permits the operator to custom-select all
technique parameters (mA, kVp, mAs/time).

READY FOR EXPOSURE*

*In all operating modes, the user always has the capability to
override any technique parameter individually, providing
uncompromised flexibility and control.

Time and date are displayed
for operator convenience.

In addition, the control panel allows the user to
toggle between viewing either mAs or SEC (time).

Quantum generators and systems are already designed to allow use of direct
digital imaging technology (DR) as well as all CR solutions.
