DICOM PS3.10 2019c - Media Storage and File Format for Media Interchange

1 Scope and Field of Application

This Part of the DICOM Standard specifies a general model for the storage of Medical Imaging information on removable media. The purpose of this Part is to provide a framework allowing the interchange of various types of medical images and related information on a broad range of physical storage media.

This Part specifies:

  1. a layered model for the storage of medical images and related information on storage media. This model introduces the concept of Media Storage Application Profiles, which specify application specific subsets of the DICOM Standard to which a Media Storage implementation may claim conformance. Such a conformance applies only to the writing, reading and updating of the content of storage media. Specific Application Profiles are not included in this Part but in PS3.11;

  2. a DICOM File Format supporting the encapsulation of any Information Object Definition;

  3. a Secure DICOM File Format supporting the encapsulation of a DICOM File Format in a cryptographic envelope;

  4. a DICOM File Service providing independence from the underlying media format and physical media. The policies specific to the DICOMDIR file used to store the Media Storage Directory Service/Object Pair Class are also addressed.

This Part is related to other parts of the DICOM Standard in that:

PS3.10 lays a foundation for open Media Interchange by standardizing an overall architecture and addressing some of the major barriers to interoperability: the definition of a DICOM File Format, a DICOM File Service and the policies associated with a Media Storage Directory structure.

Note

PS3.3 specifies a general medical imaging Basic Directory Information Object Definition and PS3.4 specifies the corresponding Media Storage Directory SOP Class that is a member of the Media Storage Service Class.

Adherence to the provisions of PS3.10 by implementations reading, writing or updating Storage Media represents a key foundation for open Storage Media Interchange. However, it is only with the selection of standard Physical Media and corresponding Media Formats in PS3.12 and the use of specific Application Profiles in PS3.11 that effective Media Storage Interchange interoperability is achieved. Therefore, claiming conformance to PS3.10 only, is not a valid DICOM Conformance Statement. DICOM Media Storage Conformance shall be made in relation to a PS3.11 Application Profile according to the framework defined by PS3.2.
