Evolving Medical Imaging Agents via Experience-driven Self-skill Discovery

MACRO is a self-evolving AI agent for medical imaging that autonomously discovers and composes specialized diagnostic tools from clinical experience. Unlike static systems, it learns effective multi-step tool sequences from verified cases, synthesizes them into reusable composites, and continuously expands its capabilities. Using visual-clinical memory and reinforcement learning, MACRO improves diagnostic accuracy and generalization across diverse medical imaging tasks with minimal supervisio...
