arXiv:2606.03888v1 Announce Type: cross Abstract: Self-supervised learning has enabled large-scale pre-training on 2D natural images, producing general-purpose visual representations that transfer effectively across tasks. However, many medical imaging modalities, such as CT scans, are inherently three-dimensional and differ fundamentally from natural images in both structure and semantics. Volumetric modalities capture spatial continuity, organ anatomy, and intensity-based tissue properties (e.g., Hounsfield Units), which are not adequately modeled by 2D pre-training. To bridge this gap, we i
The proliferation of self-supervised learning in 2D generalized AI models is now being adapted to the more complex and specialized domain of 3D medical imaging, enabled by advancements in computational resources and dataset availability.
This development addresses a critical gap in AI's application to medical diagnostics, enabling more accurate and generalizable foundation models for healthcare that can fundamentally alter disease detection and treatment planning.
The creation of foundation models specifically designed for volumetric medical data like CT scans shifts the paradigm from niche, task-specific models to more versatile and powerful AI systems for medical imaging.
