**Project Imaging-X** is a strategic initiative to consolidate 1000+ open medical imaging datasets worldwide, breaking down data silos through systematic integration to build the foundational infrastructure for next-generation medical AI models.
> **Challenge**: Medical imaging lacks large-scale unified datasets due to clinical expertise requirements and privacy constraints, limiting the development of powerful medical foundation models.
> **Solution**: We surveyed 1000+ open-access medical image datasets, developed a systematic integration paradigm, and created a unified repository with structured metadata and reference links.
> **Impact**: Transforming fragmented small datasets into cohesive large-scale resources to accelerate medical AI research and enable robust foundation models for the biomedical community.
