SonoReasoner: Hierarchical Clinical Reasoning for Ultrasound Vision-Language Models
This paper introduces SonoReasoner, an ultrasound vision-language model that enhances diagnostic performance and consistency by explicitly formulating interpretation as hierarchical clinical reasoning, supported by the SonoFlow-1M corpus, the 7-million-scale SonoCorpus reasoning dataset, and the clinician-curated SonoVQA benchmark.
