## B.5 Media Interchange

### B.5.1 Implementation Model

#### B.5.1.1 Application Data Flow

Figure B.5.1-1. Application Data Flow Diagram for Media Storage

The Offline-Media Application Entity exports images and Presentation States to a CD-R Storage medium. It is associated with the local real-world activity "Export to CD-R". "Export to CD-R" is performed upon user request for selected patients, studies, series or instances (images or presentation states).

#### B.5.1.2 Functional Definition of AEs

##### B.5.1.2.1 Functional Definition of Offline-Media Application Entity

Activation of the "Export to CD-R" icon or menu entry will pass the currently selected patients, studies, series or instances (images or presentation states) to the Offline-Media Application Entity. The SOP Instances associated with the selection will be collected into one or more export jobs. The contents of each export job will be written to a single CD-R media.

#### B.5.1.3 Sequencing of Real-World Activities

At least one image or presentation state must exist and be selected before the Offline-Media Application Entity can be invoked. The operator can insert a new CD-R media at any time before or after invocation of the Offline-Media Application Entity. The Offline-Media Application Entity will wait indefinitely for a media to be inserted before starting to write to the CD-R device. If no CD-R media is available the export job can be canceled from the job queue.

#### B.5.1.4 File Meta Information Options

The implementation information written to the File Meta Header in each file is:

Table B.5.1-1. DICOM Implementation Class and Version for Media Storage

Implementation Class UID | 1.xxxxxxx.yyy.etc.ad.inf.usw
Implementation Version Name | EXINTMOD_01

### B.5.2 AE Specifications

#### B.5.2.1 Offline-Media Application Entity Specification

The Offline-Media Application Entity provides standard conformance to the Media Storage Service Class. The Application Profiles and roles are listed below:

Table B.5.2-1. Application Profiles, Activities and Roles for Offline-Media

Application Profiles Supported | Real World Activity | Role
STD-GEN-CD | Export to CD-R | FSC

##### B.5.2.1.1 File Meta Information for the Application Entity

The Source Application Entity Title included in the File Meta Header is configurable (see Section B.5.4).

##### B.5.2.1.2 Real-World Activities

###### B.5.2.1.2.1 Activity - Export to CD-R

The Offline-Media Application Entity acts as an FSC when requested to export SOP Instances from the local database to a CD-R medium.

A dialogue will be presented allowing the user to modify the suggested media label and provides control over the available media capacity. If the contents of the current selection do not fit on a single media an automatic separation into multiple export jobs will be suggested that can be adapted by the user.

The user will be prompted to insert an empty CD-R for each export job. The contents of the export job will be written together with a corresponding DICOMDIR to a single-session CDR. Writing in multi-session mode is not supported. The user can cancel an export job in the job queue.

###### B.5.2.1.2.1.1 Media Storage Application Profiles

The Offline-Media Application Entity support the STD-GEN-CD Application Profile.

###### B.5.2.1.2.1.1.1 Options

The Offline-Media Application Entity supports the SOP Classes and Transfer Syntaxes listed in the Table below:

Table B.5.2-2. IODs, SOP Classes and Transfer Syntaxes for OfflineMedia

Information Object Definition | SOP Class UID | Transfer Syntax | Transfer Syntax UID
--- | --- | --- | ---
Media Storage Directory Storage | 1.2.840.10008.1.3.10 | Explicit VR Little Endian | 1.2.840.10008.1.2.1
X-Ray Radio Fluoroscopic Image Storage | 1.2.840.10008.5.1.4.1.1.12.2 | Explicit VR Little Endian | 1.2.840.10008.1.2.1
Grayscale Softcopy Presentation State Storage | 1.2.840.10008.5.1.4.1.1.11.1 | Explicit VR Little Endian | 1.2.840.10008.1.2.1

### B.5.3 Augmented and Private Application Profiles

EXAMPLE-INTEGRATED-MODALITY does not support any augmented for private application profiles.

### B.5.4 Media Configuration

All local applications use the AE Titles configured via the Service/Installation Tool. The Application Entity Titles configurable for Media Services are listed in the Table below:
