Validation and commissioning of AI contouring tools

Abstract

Abstract text Artificial Intelligence (AI) has become ubiquitous in modern life, and has inevitably found uses in the clinic. The recent approval of several commercial tools for OAR segmentation has accelerated the uptake of AI contouring tools, and their validation, commissioning and ongoing QA is now of great interest and importance. In this lecture, we will explore the fundamental process by which an AI contouring tool produces contours, and investigate the implications on validation and commissioning. We will compare the commissioning of an AI tool to that of a standard registration-based tool with which the community is already familiar and highlight particular pitfalls specific to AI tools that may not have been encountered when commissioning other tools. As a concrete example, we will look at work done by colleagues at The Christie Hospital, UK during their commissioning an AI contouring workflow.
