XDS-I

XDS for Imaging (XDS-I) is an extension to the IHE XDS protocol explicitly for imaging, which stores a DICOM Key Image Note (aka Key Object Selection Document) as the stored object in the Document Repository which in turn lines to the images in the “Image Source” (normally the original PACS, or perhaps a regional equivalent).

The images can be retrieved using either C-MOVE or more commonly using WADO
