Access URI for a container file containing all SOP Instances for this Study. See Section C.38.1.2.7.
Section C.38.1.2.7
C.38.1.2.7 Folder Access URI and File Access URI
If all of the stored SOP Instances of the Study, as identified in this Item, are in the DICOM File Format accessible through a non-DICOM protocol, and all the files are catalogued in a single folder (see Section P.1.3), Folder Access URI (0008,0408) provides the URI for protocol operations on that folder.
If all of the stored SOP Instances of the Study, as identified in this Item, are in a single container file as specified in Section P.1.2, File Access URI (0008,0409) provides the URI for accessing that file.
Folder Access URI (0008,0408) and/or 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 URI is merged with the Stored Instance Base URI (0008,0407) applicable to this Study (see Section C.38.1.2.6).
See Section C.38.1.4.3 for requirements on applying metadata from the Inventory SOP Instance to stored SOP Instances of the Study.
Note
-
The Study may be inventoried in more than one Item (see Section C.38.1.1.6). Only the SOP Instances identified within this Item (and its subsidiary Inventoried Instances Sequence (0008,0425) Attributes) need to be included in the folder or container file.
-
Stored SOP Instances from other Studies may be present in the folder or container file; the only requirement is that all of the identified SOP Instances of this Study are included.
-
If the SOP Instances of the Study are split across different container files, e.g., Series 1 and 2 in one container and Series 3 in a different container, then the conditional requirement for File Access URI (0008,0409) is not met and that Attribute is not used. However, if both of those container files are in the same folder, then Folder Access URI (0008,0408) may be present.
-
Files other than stored SOP Instances may be present in the folder or container file, e.g., reports in a non-DICOM file format.
-
These URIs provide complete access paths to the referenced folders and files, unlike the Retrieve URL (0008,1190) for the Studies Service (Section 10 “Studies Service and Resources” in PS3.18), which requires composition of the URI using the Study, Series, and/or SOP Instance UIDs.
