DEFINITION

Classification: 250/588

With erasure:

(under subclass 581) Subject matter including means which are directed particularly to the reversal of the response of the radiation responsive material to enable its re-use for subsequent image recordings.

(1) Note. The reversal is usually termed "erasure" when using stimulable phosphor sheets. Erasure may also be necessary to remove "fog" which develops in the sheets overtime; e.g., from incorporated radioactive isotopes.
