2. The Problem

Specific structure templates may be developed by cooperative oncology groups for certain protocols. Treatment planning systems need to be able to import the structure templates to allow for consistent evaluation of clinical data for national clinical trials.The need to import and export structure templates for patients being treated at multiple institutions using different platforms exists. Patients being transferred or receiving retreatment could benefit from the ability to import and export the structure template.

3. Key Use Case

a. A DICOM file containing a list of clinical structure names can be created in the treatment planning contouring workspace. Clinical structures can be contoured under each identifying structure name.

b. A DICOM file containing a list of clinical structure names can be imported into the treatment planning contouring workspace. Clinical structures can be contoured under each identifying structure name.

c. Using an existing treatment plan a structure template can be created from the structures defined in the treatment plan. The newly created structure template can be exported as a DICOM file.

4. Standards & Systems

Treatment planning system, record and verify system, virtual simulation system.

5. Discussion

This an ideal interoperability case for IHE-RO. It also promotes collaboration with clinical trials groups
