ADC Compact Plus, intended use
This device must only be used to scan exposed X-ray cassettes, containing
an erasable image plate (IP). This device is part of a system, consisting of X-
ray cassettes with erasable phosphor image plates, an identification station
for the cassettes and a workstation where the resulting digital image
information is further processed and routed. It is intended that this device is
only operated in a radiological environment by qualified staff.

2231C EN 20040224
ADC Compact Plus features
The ADC Compact Plus scans the exposed ADC image plate, converts the
information into digital data and automatically transfers the image to the
image processing station for further processing and visualization.
The ADC Compact Plus requires but little manual interaction. All you have to
do, after exposure and identification of the cassette, is to place it in the input
buffer of the ADC Compact Plus. You can deposit up to 10 cassettes of
different sizes simultaneously in the input buffer. The Digitizer takes in the
cassettes one by one. The Digitizer reads the demographic data and routing
information from the memory chip in the cassette, opens the cassette,
removes the image plate and scans the latent image by means ofa sweeping
laser beam.
Once the image is digitized, the cassette is returned to the output buffer to be
used for new exposures. After a full Digitizer cycle, the plate has turned 180°
in the cassette.
Depending on the X-ray intensity which has affected the phosphor during the
exposure, more or less light will be emitted during laser scanning. The light is
converted into an electrical signal. This signal is then converted into a digital
bit stream. Once converted into digital form, the digitized image is transferred
to the image processing station for further processing and visualization.
Further features of the ADC Compact Plus include:
"The ADC Compact Plus permits assigning the status ‘emergency’ to an
image. An emergency image will be given priority by the image processing
station.
"The ADC Compact Plus permits re-erasing an image plate before re-using it.
In specific cases, this is necessary to prevent ghost images caused by
previous exposures or stray radiation from interfering with the image of
interest. You can erase a batch of up to 9 image plates.

Safety precautions
General safety instructions
•For software and other technical platforms, and/or in combination with any
consumable, which constitute, after installation, a system for the interpretation of
medical image data: such system is used by trained and qualified professionals.
It is the user's responsibility to ensure that image quality, display quality,
environmental lighting and other possible distractions are consistent with the
clinical application. The user must be aware, that automatic collimation could
possibly lead to misinterpretation of the image.
•Make sure that the ADC Compact Plus is constantly monitored in order to avoid
inappropriate handling, especially by children.
•Only trained service personnel must make repairs. Only authorized service
personnel must make changes to the ADC Compact Plus.
•If there is any visible damage to the machine casing, do not start nor use the
ADC Compact Plus.
•If you want to connect the ADC Compact Plus with other devices, components or
assemblies and if the technical data do not permit determining whether the
combination with these devices, components or assemblies involves hazards,
you must consult the respective manufacturers to avoid danger for operating
personnel or the environment.
•Do not override or disconnect the integrated safety features.
•As is the case for all technical devices, the ADC Compact Plus must be
operated, cared for and serviced correctly.
•If you don’t operate the ADC Compact Plus correctly or if you don’t have it
serviced correctly, Agfa-Gevaert is not liable for resulting disturbances, damages
or injuries.
•When installing the ADC Compact Plus, care must be taken to ensure that there
is either a mains plug or an all-cable disconnecting device in the internal
installation fitted near the ADC Compact Plus and that it is easily accessible.
•If you notice conspicuous noise or smoke, disconnect the ADC Compact Plus
immediately.
•Check that the mains voltage is within the specified range of the self adapting
power supply of the machine.

Markings and labels
Always take into account the markings and labels provided on the inside and
outside of the machine. A brief overview of these markings and labels and
their meaning is given below.
Safety warning, indicating that the ADC Compact Plus Manuals
should be consulted before making any connections to other
equipment. The use of accessory equipment not complying with
the equivalent safety requirements of this Digitizer may lead to a
reduced level of safety of the resulting system. Consideration
relating to the choice of accessory equipment shall include:
• Use of the accessory equipment in the patient vicinity,
• Evidence that the safety certification of the accessory equipment
has been performed in accordance with the appropriate IEC 601-
1 and IEC 601-1-1 harmonized national standard.
In addition all configurations must comply with the medical
electrical systems standard IEC 601-1-1. The party that makes the
connections acts as system configurator and is responsible for
complying with the systems standard.
If required contact your local service organization.
In order to reduce the risk of electric shock, do not remove any
covers.
Caution hot:
Keep hands clear from the erasure unit.
Type B equipment:
Indicates that the ADC Compact Plus complies with the limits for
type B equipment.

10 2231C EN 20040224
•You can hurt your fingers if they are caught between the ADC Cassette and the
edge of the input slot. Insert the cassette in the input buffer as described in
‘Reading an image plate’ on page 26. At all times, keep your fingers clear of the
input slot. As soon as the ADC Compact Plus takes in the cassette, release it.
Supplementary protective earth connector:
Provides a connection between the ADC Compact Plus and the
potential equalization busbar of the electrical system as found in
medical environments. This plug should never be unplugged
before the power is turned off and the power plug has been
removed.
Intergrounding connector:
Provides a connection between the Digitizer and other equipment
which might exhibit minor ground potential differences. These
differences may degrade the quality of communication between
different equipment. Never remove connections to this terminal.
Protective earth (ground):
Provides a connection between the Digitizer and the protective
earth of the mains. Do not remove this connection, because this
will have a negative influence on the leakage current.
Power on
Power off
Note that the power cord has to be disconnected from the wall
outlet in order to disconnect the unit entirely from the mains.
Precautions for use in USA only:
Make sure that the circuit is single-phase center-tapped, if the
Digitizer is connected to a 240 V/60 Hz source instead of a 120 V/
60 Hz source.

2231C EN 20040224
TÜV safety issues
Accessory equipment connected to the analog and digital interfaces must be
certified according to the respective IEC standards (e.g. IEC 950 for data
processing equipment and IEC 601-1 for medical equipment). Furthermore
all configurations shall comply with the valid version of the system standard
IEC 601-1-1. Everybody who connects additional equipment to the signal
input part or signal output part configures a medical system, and is therefore
responsible that the system complies with the requirements of the valid
version of the system standard IEC 601-1-1. If in doubt, consult your local
service organization.
Safety instructions for laser products
The ADC Compact Plus is a Class 1 Laser Product. It uses a 2x50 mW laser
diode, classification class IIIb.
Under normal operating conditions - when both doors are closed - there can
be no laser radiation outside the ADC Compact Plus. It is nonetheless
imperative that the local radiation safety regulations regarding the protection
of staff against scattered radiation are complied with, if the ADC Compact
Plus is located in the immediate vicinity of an X-ray room.
Open the front left and right door only to solve cassette or image plate jams.
When you open either of the doors, the power supply of all critical
components is switched off automatically as a precaution.
User interventions other than those described in this manual can be
hazardous with regard to laser radiation.
