RIHA: Report-Image Hierarchical Alignment for Radiology Report Generation
Researchers propose RIHA, a novel transformer-based framework that generates radiology reports from medical images by performing hierarchical alignment between visual and textual features across multiple levels. The method outperforms existing approaches on benchmark chest X-ray datasets by treating reports as structured documents rather than flat sequences, improving both clinical accuracy and natural language quality.
