Commissioning and Quality Assurance of Deformable Image Registration for Current and Future Radiotherapy Applications

Chairs: Mohammad Hussein and Michael Jameson

Motivation:

Deformable Image Registration is now integrated in most commercial radiotherapy treatment planning and related imaging software. Deformable Image Registration is becoming an essential tool in a variety of applications such as multimodality image registration, guiding and adapting treatment delivery to account for changes patient anatomy, contour propagation, dose propagation, retreatments, and in follow-up studies investigating the effects and outcomes of radiotherapy. However, a challenge for radiotherapy departments is in safe commissioning and confidence in using DIR algorithms, and developing ongoing quality assurance (QA). Some of the challenges include: how to robustly quality assure (QA) and validate DIR, what to do if there is a problem with the registration in a clinical system, how to apply the results of the deformation to warp radiotherapy dose distributions and the need for clinically relevant metrics. Furthermore, an understanding of appropriate use and application of DIR to different clinical situations is required.  Guidelines such as AAPM TG132 have been proposed, however different surveys conducted in cancer centres internationally have highlighted the need for further guidance particularly in newer areas such as dose propagation. This workshop aims to bring together clinical scientists, researchers and manufacturers with an interest in current and future DIR applications, and commissioning and QA of these to discuss the issues mentioned above and encourage networking and collaboration in this area.

Outcome:

Potential outcomes could include:

- unified recommendation and guidance documents. 

- recommendations to the manufacturers based on participant feedback and discussion.

- DIR datasets that could be used by the community
