DICOM Conformance Summary of Orthanc
====================================

This document is a summary of the SOP Classes and transfer syntaxes
supported by Orthanc, together with a short description of the
transfer syntax selection policy implemented by Orthanc.

It is *not* a formal DICOM Conformance Statement (DCS) in the sense of
the DICOM standard, i.e., as defined by DICOM PS3.2 (either the
pre-2023 Annex A format, such as in DICOM PS3.2-2022d, or the current
Annex N format). It does not follow the structure, and it does not
contain all of the information, required of a formal DCS. Vendors and
integrators who need a full DCS for a specific Orthanc-based product
should refer to that product's own documentation.

---------------------
Store SCU Conformance
---------------------

All the SOP Classes that are listed in the "Store SCP Conformance"
(see above) section are available as an SCU for C-Store.


--------------------
Find SCU Conformance
--------------------

Orthanc supports the following SOP Classes as an SCU for C-Find:

  FINDPatientRootQueryRetrieveInformationModel  | 1.2.840.10008.5.1.4.1.2.1.1
  FINDStudyRootQueryRetrieveInformationModel    | 1.2.840.10008.5.1.4.1.2.2.1


--------------------
Move SCU Conformance
--------------------

Orthanc supports the following SOP Classes as an SCU for C-Move:

  MOVEPatientRootQueryRetrieveInformationModel  | 1.2.840.10008.5.1.4.1.2.1.2
  MOVEStudyRootQueryRetrieveInformationModel    | 1.2.840.10008.5.1.4.1.2.2.2


-------------------
Get SCU Conformance
-------------------

Orthanc supports the following SOP Classes as an SCU for C-Get:

  GETPatientRootQueryRetrieveInformationModel    | 1.2.840.10008.5.1.4.1.2.1.3
  GETStudyRootQueryRetrieveInformationModel      | 1.2.840.10008.5.1.4.1.2.2.3


-----------------
Transfer Syntaxes
-----------------

Orthanc will accept and negotiate presentation contexts for all of the
abovementioned supported SOP Classes using any of the following
transfer syntaxes:

  {{#transfer_syntaxes}}
  {{name}} | {{uid}}
  {{/transfer_syntaxes}}

It is possible to disable a subset of these transfer syntaxes thanks
to the "AcceptedTransferSyntaxes" and "*TransferSyntaxAccepted"
options in the Orthanc configuration file.

When possible, Orthanc will prefer the
LittleEndianExplicitTransferSyntax transfer syntax
(1.2.840.10008.1.2.1).

Orthanc does not support extended negotiation.


--------------------
Implementation notes
--------------------

The information above about the SCP support is readily extracted from
the function "Orthanc::Internals::AcceptAssociation()" from file
"OrthancFramework/Sources/DicomNetworking/Internals/CommandDispatcher.cpp".

The information above about the SCU support is derived from the
classes "Orthanc::DicomControlUserConnection" and
"Orthanc::DicomStoreUserConnection" from file
"OrthancFramework/Sources/DicomNetworking/DicomControlUserConnection.cpp" and
"OrthancFramework/Sources/DicomNetworking/DicomStoreUserConnection.cpp".
