This keyword dictionary defines keywords which may be used in image data recorded by the data acquisition system. It currently does not consider keywords for data processing. Most of the keywords defined here will not be used. New parameters must be added to the logical class heirarchy and then a keyword defined in this dictionary before use in image data.
