Safety Recommendations
7
Acquisition and storage of Images
Images acquired during examinations are stored on an internal disk system for preliminary assessment,
before permanent archiving or printing to film. The system is designed to avoid all foreseeable problems
during the acquisition and storage operations. Precautions include continuous checks on all components
and the provision of a battery-backed UPS (Uninterruptable Power Supply), to allow correct processing
of images to be completed before shutdown in the event of a power failure.
Certain conditions may cause a loss in the ability of the system to acquire high quality images or a risk
that images might not be correctly saved (for example, if the UPS batteries are not sufficiently charged to
ensure correct shutdown). For these conditions a warning message is displayed on the Liquid Crystal
Display (LCD) monitor and/or the Gantry X-ray Console. A list of possible error messages, with explana-
tions and suggested actions, is given in Chapter
.
You should note the following recommendations:
•
Always follow the correct system shutdown procedure as described in Chapter
.
•
In spite of the presence of the UPS, it is not advisable to switch off power while an image is being
processed and stored.
•
If defects or failures on the disk system are observed,
call your GEMS Service representative
. It may
be possible to recover information on the disk if the damage is not too severe.

Archiving
CAUTION
The digital technology used by the Senographe DS Control Station provides the ability to
transfer acquired images between workstations, and to store them on hard disk. However,
it is not intended or approved for use as an Archiving device.
9
AOP Mode
The Senographe DS provides an AOP (Automatic Optimization of Parameters) operating mode. This
mode is designed to optimize image quality for the examination of breasts with a compressed thickness
between 10 mm (0.4 inch) and 80 mm (3.15 inches).
However, there are some types of examination for which manual selection of parameters may be more
suitable. These are discussed in Chapter
.
Note:
GE recommends that Standard (STD) and Dose (DOSE) mode be used for routine mammography.
The Senographe DS Contrast (CNT) mode delivers more dose than Standard and Dose modes.
GE recommends that Contrast mode be used only after consultation with an interpreting physician
or radiologist.
Note:
To fulfill the requirements of certain countries, if desired, access to Contrast Mode can be restricted
as described in the Service Documentation.
