IHE Radiology Technical Framework Supplement - XDS-I.b______________________________________________________________________________415420425430435440PDFTo maximize interoperability of the chosen formats, the following restrictions shall be required:For PDF documents:We are not requiring a particular PDF version but we recommend the use of thePDF/A (ISO 19005-1)For CDA wrapped Text Documents:Text shall be encoded with UTF-8 UNICODE format. Refer to section4.68.4.1.2.3.5 for constraints on the CDA wrapper. To the extent possible, thespecification for the CDA wrapper for the report text has been made consistentwith the CDA metadata specified in the ITI XDS Scanned Documents (XDS-SD)Profile (see also ITI TF-2: 5.2.3).A report (no matter what document format is chosen) can be shared with or without imagereference(s).If a shared report includes image reference(s), it can embed selected images in its PDF format orit can include fully resolved hyperlinks that point to the selected images; these hyperlinks can beinteractively clickable (e.g. PDF) or can be processed or copied (e.g. text).The Imaging Document Source that provides and registers the shared report is responsible forformatting the hyperlink to reference relevant images. The referenced images within a sharedimaging report are meant to be accessed without the need for specialized (e.g., DICOM) viewingapplications.The hyperlink that references the selected image shall be formatted as a DICOM WADO URI.Since the sharing environment is inherently cross-enterprise, the secured version of HTTP (i.e.HTTPs) shall be used when formatting the hyperlink.The Imaging Document Source is required to ensure that image references are valid links.Even though significant images can be shared as non-DICOM format (embedded picture in PDFreport or hyperlinks in PDF or Text report), it is required that sharing of a large set of DICOMimages be achieved by sharing a set of DICOM SOP instances by providing and registering amanifest document. This is to avoid registration of a large number of individual documents in theXDS Document Registry.4.68.4.1.2.3 Metadata445The Provide and Register Imaging Document Set – MTOM/XOP Request message shall includethe metadata attributes that will be forwarded by the XDS Document Repository Actor to theXDS Registry Actor using the Register Document Set-b Transaction (ITI-42).__________________________________________________________________________Rev. 1.1 - 2009-06-2122Copyright © 2009: IHE International
