Proposal

This page lists first proposals for Query/Retrieve in Radiation Oncology Profile. Based on the information collected here and the discussion within the IHE-RO TC a Use Case shall be drafted on the official ihe.net wiki. Based on this, development of a profile may start then.

Clinical Use Cases

  1. Basic archive (PACS, R&V) access for pre-planning/planning/planning verification/…
  2. Access e.g. specific plans or treatment records via specific attributes without retrieving all of the instances and looking through them on the client side
  3. Faster transfer of big data sets (which start to get bigger by adding e.g. registrations, presentation states, …)

Technical Challenges

Start easy, add levels of complexity:

Basic Q/R

Define attributes for query on

  • study,
  • series and
  • instance level

See RAD profile (transaction RAD-14) for that.

C-MOVE from remote to local, but also (optionally) C-MOVE from remote to remote.

Define/test how matching should work
  • A search for patient ID “1” should not return a patient with ID 123. A search with “1*” however should return Patient ID 123.

Instance Level Query

Define set of instance level query attributes for 1st Gen RT objects.

Image objects
  • Frame of Reference (hmaclean: to be able to group objects for the user without having to download them first)
RT Structure Set
  • Frame of Reference
  • Structure Set Label
  • Structure Set Name
  • Structure Set Date
  • Structure Set Time
  • Referenced Frame of Reference Sequence - Related Frame of Reference UID (this is in a sequence - need to define how to handle)
  • Number of ROIs ? (there is no attribute for that)
RT Plan
  • Frame of Reference
  • RT Plan Label
  • RT Plan Name
  • RT Plan Date
  • RT Plan Time
  • Referenced Structure Set
RT Dose
  • Frame of Reference
  • Referenced RT Plan
RT Image
  • Referenced RT Plan
Treatment Record
Registration

Mulitple Associations

Define handling of multiple associations for faster transfer of data

Asynchronous Associations

Define handling of asynchronous associations for faster transfer of data

Relational Queries

With new objects such as registration, segmentations, fiducials or presentation states starting to get used in the RO domain, and an increased complexity of dependencies within 2nd Gen RT objects, relational queries will ease querying for information.

Instance Level Query 2nd Gen

Define set of instance level query attributes for 2nd Gen RT objects.
