Abstract: Medical Visual Language Models have shown great potential in various
healthcare applications, including medical image captioning and diagnostic
assistance. However, most existing models rely on text-based instructions,
limiting their usability in real-world clinical environments especially in
scenarios such as surgery, text-based interaction is often impractical for
physicians. In addition, current medical image analysis models typically lack
comprehensive reasoning behind their predictions, which reduces their
reliability for clinical decision-making. Given that medical diagnosis errors
can have life-changing consequences, there is a critical need for interpretable
and rational medical assistance. To address these challenges, we introduce an
end-to-end speech-driven medical VLM, SilVar-Med, a multimodal medical image
assistant that integrates speech interaction with VLMs, pioneering the task of
voice-based communication for medical image analysis. In addition, we focus on
the interpretation of the reasoning behind each prediction of medical
abnormalities with a proposed reasoning dataset. Through extensive experiments,
we demonstrate a proof-of-concept study for reasoning-driven medical image
interpretation with end-to-end speech interaction. We believe this work will
advance the field of medical AI by fostering more transparent, interactive, and
clinically viable diagnostic support systems. Our code and dataset are publicly
available at SiVar-Med.
