Access URI for a file containing the SOP Instance. See Section C.38.2.2.1.1.
Required if the referenced SOP Instance is in the DICOM File Format, and is accessible through a non-DICOM protocol (see Annex P).
File Access URI (0008,0409) provides the URI for accessing a file containing the SOP Instance in the DICOM File Format. The file may contain a single SOP Instance, or it may be a container file in which one or more SOP Instance files are included.
File Access URI (0008,0409) may be a relative path reference beginning with the single-dot-segment "./" (see Section P.2.1). In this case, the value is merged with a Stored Instance Base URI (0008,0407) specified for the context of this Attribute in accordance with Section P.2.1.
The merge of a relative path File Access URI (0008,0409) with a Stored Instance Base URI (0008,0407) involves only two Attribute values. For example, a relative path specified at the Instance level is not merged with any Study or Series level relative path values, but only with a base URI. This contrasts with the web-based Studies Service of PS3.18, which might require constructing a URI from a base URI in the Retrieve URL (0008,1190), DICOM-defined strings, a Study Instance UID (0020,000D), a Series Instance UID (0020,000E), and a Referenced SOP Instance UID (0008,1155).
