Gate RTion project
The OpenGATE collaboration is willing to help clinical users setting-up GATE into the clinics. We are currently about 6 different ion therapy centers using, or about to use, GATE for clinical purposes.
- Providing a stable and long term GATE release, called GATE-RTion, having all necessary features for dosimetric applications in Light Ion Beam Therapy facilities equipped with the Pencil Beam Scanning delivery technique.
- Providing a collection of tools necessary for the clinical users to interface GATE with the clinical environment
- Developing guidelines for clinical users on how to implement GATE into the clinical routine using the provided tools
We plan to release the first version of GATE-RTion by the end of 2017 with all proton functionalities validated. Further releases will include carbon ion functionalities and other features.

The Open Resources for GATE Monte Carlo simulations (Open-ReGate) platform will be used to share and document all necessary Tools, including guidelines. https://public.kitware.com/open-regate/index.php/Main_Page
The proposed release plan below provides only the main objectives:
- GATE-RTion V 1.0: all necessary features for dosimetric applications in Light Ion Beam Therapy facilities equipped with the Pencil Beam Scanning delivery technique for Protons + a set of Tools for the user
- GATE-RTion V2.0: Extension of V1.0 to carbon ion delivery
New functionalities provided by the members of the OpenGATE collaboration will be available in the standard GATE release, however they will only be part of a new GATE-RTion release if clinical user interest is raised and common effort agreed with the uses to validate the features. The developments listed below have been identified of potentially interest for the clinical users in future:
- RBE modeling and implementation of the MKM model (Lydia Maigne)
- 4D simulations including 4D CT and 4D treatment delivery (David Boersma)
