Centricity™ MP3510, 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.

Centricity™ MP3510 features

The Centricity™ MP3510 scans the exposed Centricity™ CR compatible

image plate, converts the information into digital data and automatically

transfers the image to the image processing station for further processing and

visualization.

The Centricity™ MP3510 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 Centricity™ MP3510. 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 Centricity™ MP3510 include:

nThe Centricity™ MP3510 permits assigning the status ‘emergency’ to an

image. An emergency image will be given priority by the image processing

station.

nThe Centricity™ MP3510 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.

nThe Pathspeed™ CR Digitizers (Pathspeed™ SP1001 and Pathspeed™

MP3010) and the Centricity™ CR Digitizers (Centricity™ SP1001 and

Centricity™ MP3510) are designed for operation with Agfa CR cassettes and

Agfa CR phosphor plates. Contact your local GE Medical Systems sales

agent for product and ordering information.

Safety precautions

General safety instructions

•Make sure that the Centricity™ MP3510 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 Centricity™ MP3510.

•If there is any visible damage to the machine casing, do not start nor use the

Centricity™ MP3510.

•If you want to connect the Centricity™ MP3510 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 Centricity™ MP3510 must be

operated, cared for and serviced correctly.

•If you don’t operate the Centricity™ MP3510 correctly or if you don’t have it

serviced correctly, GE Medical Systems Information Technologies is not liable for

resulting disturbances, damages or injuries.

•When installing the Centricity™ MP3510, 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 Centricity™ MP3510 and that it is easily accessible.

•If you notice conspicuous noise or smoke, disconnect the Centricity™ MP3510

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 Centricity™ MP3510 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 Centricity™ MP3510 complies with the limits for

type B equipment.

•You can hurt your fingers if they are caught between the Centricity™ CR

compatible Cassette and the edge of the input slot. Insert the cassette in the

input buffer as described in

‘Reading an image plate’

on page

. At all times,

keep your fingers clear of the input slot. As soon as the Centricity™ MP3510

takes in the cassette, release it.

Supplementary protective earth connector:

Provides a connection between the Centricity™ MP3510 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.
