Proof of concept - not an authoritative source.
The accession number issued by a RIS for an imaging request - NHS Data
Dictionary RADIOLOGICAL ACCESSION NUMBER.
Based on HL7 Europe Imaging AccessionNumberIdentifierEuImaging (type ACSN).
DICOM (0008,0050) Accession Number, with the issuer in (0008,0051); HL7 v2 CX
with CX.5 ACSN and CX.6 the assigning facility.
Accession numbers are unique only within the issuing RIS, so system must
identify the issuer. A convention for the system URI is Open.
