Idea
A medical imaging AI model that improves tumor classification accuracy for radiologists using CT scans with multi-modal knowledge transfer.
Research Paper
Core Innovation
This paper introduces REACT-KD, a framework that distills knowledge from high-fidelity multi-modal data into a lightweight CT-based model. It uniquely employs dual teachers to capture both structure-function relationships and dose-aware features, guiding the student model through semantic and anatomical topology alignment. This approach improves interpretability and robustness across varying CT dose levels compared to prior single-modal or less integrated methods.
