V ZIP File Media (Normative)

V.1 DICOM Mapping to ZIP File

V.1.1 DICOM File-set

One and only one DICOM File-set shall be contained in a ZIP File archive.

Each DICOM SOP Instance shall be encoded in accordance with the rules in PS3.10.

Note

A ZIP File may contain files that are not referenced by the DICOMDIR, which may be ignored by the DICOM application.

V.1.2 DICOM File ID Mapping

The ZIP encoding preserves the hierarchical structure for directories and files within directories. Each volume has a root directory that may contain references to both files and sub-directories. Sub-directories may contain reference to both files and other sub-directories.

V.1.2.1 File ID

PS3.10 defines a DICOM File ID Component as a string of 8 characters from a subset of the G0 repertoire of ISO 8859.

Note

The use of long file names is prohibited.

Filename extensions are not used in DICOM File ID Components, hence a File Identifier shall not contain a File Extension or the '.' that would precede such a File Extension.

The maximum number of levels of a path name in a ZIP file-set shall be at most 8 levels, to comply with the definition of a DICOM File-set in PS3.10.

V.1.2.2 DICOMDIR

One and only one DICOMDIR File shall be present. The DICOMDIR shall be at the root directory of the File-set.

Note

The reason for the DICOMDIR is to serve as a manifest so that the recipient knows the full list of instances intended to be sent.
