Re-Erasing An Image Plate - GE CRxVision Operating Manual

Re-erasing an Image Plate

Press the erase button
At the end of a normal digitizing cycle, the CRxVision returns an erased image plate.
However, in the following cases, you must re-erase the image plate before re-using it in order
to prevent ghost images from interfering with the image of interest:

If the image plate has not been used for more than 48 hours.

If an image plate has been exposed to an exceptionally high X-ray dose.
In this case, deep layers of the image plate may still retain a latent image after standard
erasure. Leave the image plate to rest at least one day before re-erasing it.
To re-erase an image plate:
1 Check that the CRxVision is in standby mode: The status indicator is slow red
blinking (  1 / sec.)
2 Press the erase button at the front side. The status indicator is continuously lighting
up in blue. If within one minute no image plate is entered, the CRxVision returns to
the standby mode.
3 Put the image plate on the input table with the white (IPS / IPS2 / IPC2 for CRxVision)
or blue (IPU for CRxVision) side facing up.
4 Align the image plate with the alignment bar (A) and push it into the CRxVision (B),
until the magnetic scan roller takes over the image plate. As a result, the CRxVision
starts erasing the image plate: The status indicator switches to the state "blue
blinking".

5 When the status indicator switches to "constant blue", the image plate has left the
scan roller, and the CRxVision accepts another image plate for a time interval of
approx. 15 seconds: Insert the next image plate if required.
6 Remove the image plate when it is laying on the output table after erasure.
7 The erasure cycle is finished when the status indicator turns
