The Image Registration Integration Profile (REG) specifies communications between systems creating and registering image sets.
Summary
Transmitting registration information within the Radiation Oncology domain is becoming an increasingly important to the process of external beam radiation treatments. This profile addresses the ability to convey registered data from one system to another for further processing. This profile addresses issues dealing with multiple coordinate systems but does not specifically address the issue of repeatable fused displays.
Currently, registration can be performed on individual workstations designed for that purpose and planning systems, but the results are not readily transferable between systems, often due either to proprietary or inconsistent implementations. Coordination of data across the RT objects and registration of Image studies is discussed. A collection of DICOM objects exists to address the problem. Their use is constrained and clarified to avoid misinterpretation and promote compatibility.
Benefits
- defines how DICOM objects for spatial registration and the images themselves are created, stored, queried, retrieved, processed and displayed
- Provides transactions required for interoperability between multi-vendor systems
Details
This Integration Profile specifies how images, RT Structure Sets, RT Doses, and associated spatial registration information can be exchanged, stored, processed and displayed. For a display workstation, it is essential that a workstation correctly identifies the corresponding image sets, matches data from single-slice and multi-slice datasets, matches coordinate systems, and performs spatial translations. The use of relevant DICOM objects (Spatial Registration) is clarified and constrained in order to avoid misinterpretation.
Image Registration Integration Profile focuses on content for image registration and does not define a registration workflow. Such workflow could be managed by using mechanisms described in the Post-Processing Workflow Integration Profile.
The Image Registration Integration Profile currently only handles rigid registration. The intention is to add deformable registration as an extension to the Profile in the future.
The Image Registration Profile does not specify the use of quantification methods for the image data that is created or displayed. In particular interoperability for PET Standard Uptake Values (SUV) is considered a relevant future work item for IHE. Note that vendors may wish to prodovide SUV capability even though not required under this Profile.
