CR 75.0 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.

2241A EN 20040210
CR 75.0 features
The CR 75.0 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 CR 75.0 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 CR 75.0. 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 of a 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 CR 75.0 include:
"The CR 75.0 permits assigning the status ‘emergency’ to an image. An
emergency image will be given priority by the image processing station.
"The CR 75.0 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 CR 75.0 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 CR 75.0.
•If there is any visible damage to the machine casing, do not start nor use the
CR 75.0.
•If you want to connect the CR 75.0 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 CR 75.0 must be operated, cared for
and serviced correctly.
•If you don’t operate the CR 75.0 correctly or if you don’t have it serviced
correctly, Agfa-Gevaert is not liable for resulting disturbances, damages or
injuries.
•When installing the CR 75.0, 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 CR 75.0 and that it is easily accessible.
•If you notice conspicuous noise or smoke, disconnect the CR 75.0 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.

2241A EN 20040210
Safety warning, indicating that the CR 75.0 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 CR 75.0 complies with the limits for type B
equipment.
Supplementary protective earth connector:
Provides a connection between the CR 75.0 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.

10 2241A EN 20040210
•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 28. At all times, keep your fingers clear of the
input slot. As soon as the CR 75.0 takes in the cassette, release it.
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.
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.
