Idea
A geometry-guided visual language model for mammography that improves multi-view breast cancer detection accuracy for radiologists and healthcare providers
Research Paper
Core Innovation
This paper presents GLAM, a model that leverages geometric knowledge of mammography multi-view imaging to align local features across views. It jointly learns global and local visual and language representations through contrastive learning, unlike prior models that treat views independently or ignore multi-view correspondence. This approach captures critical geometric context, improving prediction accuracy in mammography interpretation.

Research Paper Overview
GLAM: Geometry-Guided Local Alignment for Multi-View VLP in Mammography
Summary
Mammography screening is essential for early breast cancer detection. Deep learning can improve interpretation speed and accuracy but is limited by data scarcity and domain differences from natural images. Existing visual language models adapted from natural images often ignore mammography-specific multi-view relationships. Unlike radiologists who analyze ipsilateral views together, current methods treat views independently or fail to model multi-view correspondence, losing geometric context and reducing prediction quality. GLAM introduces global and local alignment using geometry guidance to learn local cross-view alignments and fine-grained features through joint contrastive learning. Pretrained on a large mammography dataset, GLAM outperforms baselines across multiple datasets and settings.
