MMXU introduces a groundbreaking dataset enabling AI systems to analyze disease progression across multiple X-rays over time, filling a critical gap in medical visual question answering.

• Integrates historical patient records with sequential X-ray images
• Enables AI models to track changes and disease development patterns
• Advances diagnostic capabilities beyond single-image analysis
• Provides foundation for more comprehensive medical decision support

This research represents a significant step toward AI systems that can assist clinicians in longitudinal patient assessment, potentially improving diagnostic accuracy and treatment planning for progressive conditions.
