Research Paper Overview
Citrus-V: Advancing Medical Foundation Models with Unified Medical Image Grounding for Clinical Reasoning
Summary
Medical imaging is essential for diagnosis and treatment but current models are specialized and limited. Citrus-V is a multimodal medical foundation model that integrates image analysis and textual reasoning, enabling lesion localization, report generation, and diagnostic inference in one framework. It uses a novel multimodal training approach and an open-source data suite for reasoning, detection, segmentation, and document understanding. Citrus-V outperforms existing models and expert systems, providing a unified pipeline for visual grounding and clinical reasoning to support lesion quantification, automated reporting, and second opinions.
