IHE Announces Dose Compositing Supplement for Public Comment

The IHE Radiation Oncology Technical Committee has published the following profile for Public Comment:

Dose Compositing
For this profile, the term Dose Compositng is used to denote the process of combining information from two spatially-related 3-D dose (matrices) [represented as DICOM RT Dose objects]. Two use cases are supported by this profile. The first use case (Registered Dose Compositor) involves accepting two dose instances and a spatial registration instance and combining the spatially-registered doses to produce a new dose instance. The second use case (Compositing Planner) involves accepting a (prior) dose instance and a spatial registration instance and creating a new treatment plan and dose instance(s) based on the prior dose.

This Supplement can be found at
