## 6.10 PS3.10 Media Storage and File Format

PS3.10 of the DICOM Standard specifies a general model for the storage of medical imaging information on removable media (see Figure 6.10-1). 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.

### Note

See Figure 5-1 for understanding how the media interchange model relates to the network model.

PS3.10 specifies:

- 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.

- a DICOM file format supporting the encapsulation of any Information Object;

- a secure DICOM file format supporting the encapsulation of a DICOM file format in a cryptographic envelope;

- a DICOM file service providing independence from the underlying media format and physical media.

PS3.10 defines various media storage concepts:

- the method to identify a set of files on a single medium;

- the method for naming a DICOM file within a specific file system.
