Researchers have developed a novel method called the Concept Channel Probe (CCP) to identify which specific internal units within frozen 3D medical vision-language models encode particular radiological findings. This technique was successfully applied to two distinct models, Pillar-0 and Merlin, demonstrating that a sparse set of approximately ten channels can accurately represent individual findings without impacting unrelated labels. The CCP method significantly outperforms existing tools like CT-CHAT in clinical efficacy and natural language generation metrics while operating at a much lower latency. AI
