Re-erasing an image plate
At the end of a normal or emergency digitizing cycle, the CR 75.0 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 3 days.
In this case, the image plate may have been exposed to scattered radiation.
•
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.
You can erase image plates which you have given the status ‘to be erased’
via the ID Station or image plates which have the status ‘erased’. You can
erase an image plate or a batch of up to 9 plates.
