M.2.1.1 File Set Creator

The role of File Set Creator shall be used by Application Entities that generate a File Set under this Interchange Class of Application Profiles.

File Set Creators shall be able to generate the Basic Directory SOP Class in the DICOMDIR file with all the subsidiary Directory Records related to the Image SOP Classes stored in the File Set. The Application Entity acting as a File Set Creator generates a File Set under a STD-GEN-BD or STD-GEN-SEC-BD Application Profile.

An FSC shall offer the ability to finalize the physical volume at the completion of the most recent write session (no additional information can be subsequently added to the volume), if supported by the media and file system specified in the profile.

Note: A multiple volume (i.e. a logical volume that can cross multiple physical media) is not supported by this class of Application profile. If a set of Files, e.g., a Study, cannot be written entirely on one physical volume (side of one piece of media), the FSC will create multiple independent DICOM File Sets such that each File Set can reside on a single physical volume (side of a single piece of media) controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the physical volumes to indicate that there is more than one physical volume for this set of files (e.g., a study).
