一个能看懂医图、回答问题、生成报告的多模态模型
UMIT: Unifying Medical Imaging Tasks via Vision-Language Models
- 用双阶段训练让模型通吃多种医学影像任务
- 在5个任务上超越现有方法,支持中英文和多模态影像
- 适合医疗AI研发、临床辅助诊断系统开发
随着深度学习快速发展,视觉语言模型(VLM)被广泛应用于复杂医疗与生物医学挑战。然而,现有研究多聚焦特定任务或单一模态,限制了其在多样医疗场景中的泛化能力。为此,我们提出UMIT,一种专为医学影像设计的统一多模态、多任务VLM,可处理视觉问答、疾病检测、医疗报告生成等任务。它支持X光、CT、PET等多种影像模态,覆盖从基础诊断到复杂病灶分析的应用。同时,模型支持中英文,提升全球医疗可及性。通过独特的两阶段训练策略与指令模板微调,UMIT在多个数据集上的5项任务中表现优于此前方法,显著提升诊断准确率与工作流效率。
原文摘要 · Abstract (English)
With the rapid advancement of deep learning, particularly in the field of medical image analysis, an increasing number of Vision-Language Models (VLMs) are being widely applied to solve complex health and biomedical challenges. However, existing research has primarily focused on specific tasks or single modalities, which limits their applicability and generalization across diverse medical scenarios. To address this challenge, we propose UMIT, a unified multi-modal, multi-task VLM designed specifically for medical imaging tasks. UMIT is able to solve various tasks, including visual question answering, disease detection, and medical report generation. In addition, it is applicable to multiple imaging modalities (e.g., X-ray, CT and PET), covering a wide range of applications from basic diagnostics to complex lesion analysis. Moreover, UMIT supports both English and Chinese, expanding its applicability globally and ensuring accessibility to healthcare services in different linguistic contexts. To enhance the model's adaptability and task-handling capability, we design a unique two-stage training strategy and fine-tune UMIT with designed instruction templates. Through extensive empirical evaluation, UMIT outperforms previous methods in five tasks across multiple datasets. The performance of UMIT indicates that it can significantly enhance diagnostic accuracy and workflow efficiency, thus providing effective solutions for medical imaging applications.
