Entity

Medium

 

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​

- Standard -​

DICOM PS3.2 2020a - Conformance​

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:​

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:​

Application Profiles Supported​

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:​

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:​

B.6 Support of Character Sets​

All EXAMPLE-INTEGRATED-MODALITY DICOM applications support the​

ISO_IR 100 (ISO 8859-1:1987 Latin Alphabet No. 1 supplementary set)​

ISO_IR 144 (ISO 8859-5:1988 Latin/Cyrillic Alphabet supplementary set)​

If the EXAMPLE-INTEGRATED-MODALITY is configured for Cyrillic character set support, ISO_IR 144 will be used automatically.​

B.7 Security​

EXAMPLE-INTEGRATED-MODALITY does not support any specific security measures.​

ItisassumedthatEXAMPLE-INTEGRATED-MODALITYisusedwithinasecuredenvironment.Itisassumedthatasecuredenvironment​ includes at a minimum:​

a.​Firewall or router protections to ensure that only approved external hosts have network access to EXAMPLEINTEGRATED-​ MODALITY.​

b.​Firewall or router protections to ensure that EXAMPLEINTEGRATED-MODALITY only has network access to approved external​ hosts and services.​

c.​Any communication with external hosts and services outside the locally secured environment use appropriate secure network​ channels (e.g., such as a Virtual Private Network (VPN) )​

Other network security procedures such as automated intrusion detection may be appropriate in some environments. Additional se-​ curity features may be established by the local security policy and are beyond the scope of this conformance statement.​

Table B.8.1-2 specifies the attributes of a Grayscale Softcopy Presentation State transmitted by the EXAMPLEINTEGRATED-MOD-​ ALITY storage application.​

The following tables use a number of abbreviations. The abbreviations used in the "Presence of …" column are:​

VNAP​ Value Not Always Present (attribute sent zero length if no value is present)​

ANAP​ Attribute Not Always Present​

ALWAYS​Always Present​

EMPTY​Attribute is sent without a value​

The abbreviations used in the "Source" column:​

MWL​ the attribute value source Modality Worklist​

USER​ the attribute value source is from User input​

AUTO​ the attribute value is generated automatically​

MPPS​ the attribute value is the same as that use for Modality Performed Procedure Step​

CONFIG​the attribute value source is a configurable parameter​

Note​

All dates and times are encoded in the local configured calendar and time. Date, Time and Time zone are configured using​ the Service/Installation Tool.​
