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.
