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.

2242A EN 20040303

CR 75.0 featur es

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 precaution s

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.

2242A EN 20040303

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 75.0 manuals should be consulted bef ore making any connecti ons to other equipment. The use of accessory equi pm ent not complying with the equivalent safety requirem ents of this Digitizer ma y lead to a reduced level of safety of the res ulting system. Consideration relating to the choice of accessory equipment shall include:

• Use of the accessory equipment in the patient vicinity,

• Evidence that the safety cer tif icati on of the acc esso ry equip ment has been performed in accordance wit h the appropr iate IEC 6011 and IEC 601-1-1 harmonized national standard.

In addition all con figurations 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 t he systems standard .

If required contact your local servi ce organization. In order to reduce the ri sk of electric shock, do not r em ove any

covers.

Caution hot: Keep hands clear from the erasure unit.

2242A EN 20040303

Type B eq uipme nt: Indicates that th e 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 connect ion between the Digitizer and other equipment

which might exhibit minor ground potential differences. These differ ences may degrade the quality of communication between different equipment. Never remove connections to this terminal.

Protecti ve eart h (ground): Provides a connect ion 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 entir ely from the mains. Precautions for use in USA only:

Make sure that the circuit is single-phase center-tapped, if the Digitizer i s connected to a 240 V/60 Hz source instead of a 120 V/ 60 Hz source.

• 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 ima ge plat e’ on page 26. At all times, keep your fingers clear of the

input slot. As soon as the CR 75.0 takes in the cassette, release it.

2242A EN 20040303

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 CR 75.0 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 CR 75.0. It is nonetheless imperative that the local radiation safety regulations regarding the protection of staff against scattered radiation are complied with, if the CR 75.0 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.

Observe the Caution instructions on the Optical module label:
