Note: The Digital X-Ray Image Storage and Digital Intra-oral X-Ray Image Storage For Presentation SOP Classes can also be used for scanned film.

A File Set Creator (FSC) shall support at least one of the specified image storage SOP Classes.

K.3.2 Physical media and media formats

The STD-DEN-CD profile requires the 120 mm CD-R physical media with the ISO/IEC 9660 Media Format, as defined in PS 3.12.

K.3.3 Directory information in DICOMDIR

Conformant Application Entities shall include in the DICOMDIR File the Basic Directory IOD containing Directory Records at the Patient and the subsidiary Study and Series levels, appropriate to the SOP Classes in the File Set.

All DICOM files in the File Set incorporating SOP Instances defined for the specific Application Profile shall be referenced by Directory Records.

Note: DICOMDIRs with no directory information are not allowed by this Application Profile.

All implementations shall include the DICOM Media Storage Directory in the DICOMDIR file. There shall only be one DICOMDIR file per File Set. The DICOMDIR file shall be in the root directory of the medium. The Patient ID at the patient level shall be unique for each patient directory record in one File Set.

No additional DICOMDIR keys are specified for this profile.
