The Directory Record is based on the specification of Section F.3. It is identified by a Directory Record Type of Value "SPECTROSCOPY." Table F.5-27 lists the set of keys with their associated Types for such a Directory Record Type. The description of these keys may be found in the Modules related to the Spectroscopy IE of Spectroscopy IODs. This Directory Record shall be used to reference a Spectroscopy SOP Instance. This type of Directory Record may reference a Lower-Level Directory Entity that includes one or more Directory Records as defined in Table F.4-1.
