DCMTK

Since DCMTK meanwhile supports writing both the DICOM XML native model and the DICOM JSON model, it should not be too difficult to implement a STOW-RS SCU that supports the three encoding options defined in DICOM Part 18:

• DICOM Part 10 (binary DICOM file format as MIME part)
• DICOM XML native model
• DICOM JSON model

What is mainly missing is:

• support for writing the HTTP header including the MIME multipart/related structure
• support for encoding Pixel Data, Encapsulated Documents and other large binary attributes as BulkDataURI that points to another MIME part in the same output stream (both in XML and JSON)
• Since the HTTP header will require the Content-Length field, we also need functionality that either performs the DICOM/XML/JSON export as a "dry run" and only counts bytes, or we must export to a temporary file, determine the file size, and then combine this with the HTTP header.
• Functionality that creates the TCP/TLS transport connection, delivers the HTTP request, and receives the HTTP result.
