## K.2 Clinical Context

This Application Profile facilitates the interchange of dental data on media. Typical interchanges would be between dental systems, between a dental system and a display workstation, between display workstations, or between a dental system and a data archive. This context is shown in Figure K.2-1.

Figure K.2-1. Clinical Context

The operational use of the media transfer is potentially between private practitioners and an institution, intra-institutional and inter-institutional.

### K.2.1 Roles

#### K.2.1.1 File Set Creator

The role of File Set Creator shall be used by Application Entities that generate a File Set under the STD-DEN-CD Application Profile. Typical entities using this role would include dental imaging equipment, workstations, and archive systems that generate a patient record for transfer. File Set Creators shall be able to generate the Basic Directory SOP Class Instance in the DICOMDIR file and Digital Intra-oral X-Ray and Digital X-Ray Image Storage SOP Class Instances in the File Set.

An FSC shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disc).

### Note

A multiple volume (a logical volume that can cross multiple physical media) is not supported by this Application Profile Class. If a set of Files, e.g., a Study, cannot be written entirely on one CD-R, the FSC will create multiple independent DICOM File-sets such that each File-set can reside on a single CD-R media controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the discs to indicate that there is more than one disc for this set of files (e.g., a study).

#### K.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set. Typical entities using this role would include dental systems, display workstations, and archive systems that receive a patient record from a piece of media. File Set Readers shall be able to read the DICOMDIR directory file and all SOP Class Instances defined for this Application Profile, using the defined Transfer Syntaxes.

#### K.2.1.3 File Set Updater

The role of File Set Updater is not supported by this profile.
