Instance-Level Query/Retrieve
- RT objects from archive – review draft query key document from IHE-RO/TC meeting April 2006
- Issues
- Object (plan) linkage
- Revision management
- Query keys currently inadequate for RT objects
1. Proposed Workitem: Definition of RT Objects specific Query / Retrieve Keys

- Date: N/A (Wiki keeps history)
- Version: N/A (Wiki keeps history)
- Domain: Radiation Oncology
2. The Problem
An RT Archive (PACS in the Radiation Oncology Domain) is indispensable member in a clinical workflow for the establishment of medical informatics research related to outcomes for future radiation therapy patients. It is also a system where all the patient data (Images, Plans, Dose, Structures) are securely stored. In order to retrieve the data for review / re-plan / reprocess for a follow up or provide to do research and do data mining there is a need for Query Key parameters to be passed on to the Archive in order for it to send out the objects which are matching the keys.
In IHEs other domains (Radiology, Eye Care, Cardiology) there is a list of Query keys which are required by PACS or Archive systems to support. This list of parameters can identify a patient, its study and series. In addition to these keys there are more specific keys defined for retrieving specific DICOM objects (Key Image Notes, Presentation states etc). For more information on this please refer to the IHE Radiology Technical Framework Vol 2.
In Radiation Oncology specific keys on which searching can be carried out in an RT Archive is not defined.
3. How it currently works
How it should work:
Many of the current treatment planning systems do not have a DICOM Query / Retrieve mechanism to get patients treatment planning data based on the basic query keys. In order to get data for such treatment planning systems the users have to work with external PACS interfaces to push the Dicom treatment planning data from the RT Archive to the TPSs. These external PACS interfaces have very basic parameters on which the data can be searched on. Also there are no RT related search parameters, so again specific RT related information (RT plan description, treatment intent, treatment protocol, setup technique etc) objects can not be retrieved.
4. Benefits
• With these keys defined, there is an ease to retrieve only the desired objects for a patient. So for example, with these keys we could get only the approved plans from the achive for a patient that has a list of approved and unapproved plans. • For research having such keys is critical in order to do data mining and report results on a large number of patients.
5. Standards & Systems
Affected systems:
• Treatment planning systems, virtual simulation system, record & verify systems, CT, Picture Archive and Communication Systems (RT Archive – it is not picture anymore).
