CR 85-X DIGITIZER
CR 85-X 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.

4450A EN 20060221 Introducing the CR 85-X
CR 85-X DIGITIZER
CR 85-X features
The CR 85-X scans the exposed CR 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 85-X 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 85-X. 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 85-X include:
"The CR 85-X permits assigning the status ‘emergency’ to an image. An emer-
gency image will be given priority by the image processing station.
"The CR 85-X 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 85-X 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 85-X.
•If there is any visible damage to the machine casing, do not start nor use
the CR 85-X.
•If you want to connect the CR 85-X 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 85-X must be operated, cared
for and serviced correctly.
•If you don’t operate the CR 85-X 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 85-X, 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 85-X and that it is easily accessible.
•If you notice conspicuous noise or smoke, disconnect the CR 85-X
immediately.

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 CR 85-X 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 85-X complies with the limits for type B equipment.

•You can hurt your fingers if they are caught between the CR 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 85-X takes in the cassette,
release it.
Supplementary protective earth connector:
Provides a connection between the CR 85-X 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.

CR 85-X DIGITIZER
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 IEC601-1-1. If in doubt, consult your local
service organization.
Safety instructions for laser products
The CR85-X is a Class 1 Laser Product. It uses a 80 mW laser diode,
classification class IIIb.
Under normal operating conditions - when both doors are closed - there can
be no laser radiation outside the CR 85-X. It is nonetheless imperative that the
local radiation safety regulations regarding the protection of staff against
scattered radiation are complied with, if the CR 85-X 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.
