用低成本显微镜+AI实现自动宫颈癌筛查,适合资源匮乏地区

AI Assisted Cervical Cancer Screening for Cytology Samples in Developing Countries

  • 结合微型电动显微镜与轻量AI算法,实现全片自动分析
  • 在SIPaKMeD数据集上分类五类细胞准确率达92.7%
  • 只需少量标注区域即可训练,适合缺乏专家的基层医疗

宫颈癌仍是转型国家的重大健康挑战,发病率和死亡率居高不下。传统液基细胞学(LBC)流程依赖人工、耗时且易出错,亟需更高效筛查方式。本文提出一种创新方案:结合低成本生物显微镜与高效AI算法,实现全自动全片分析。系统通过电动显微镜采集细胞图像,经图像拼接、细胞分割与分类处理。采用基于轻量UNet的分割模型,并通过人机协同方式仅用少量感兴趣区域(ROIs)完成训练;分类模块采用基于CvT的模型,在SIPaKMeD数据集上对五类细胞实现高精度识别。相比多种先进方法,本框架在准确率与效率方面均表现更优,验证了其在资源有限地区的应用潜力。

原文摘要 · Abstract (English)

Cervical cancer remains a significant health challenge, with high incidence and mortality rates, particularly in transitioning countries. Conventional Liquid-Based Cytology(LBC) is a labor-intensive process, requires expert pathologists and is highly prone to errors, highlighting the need for more efficient screening methods. This paper introduces an innovative approach that integrates low-cost biological microscopes with our simple and efficient AI algorithms for automated whole-slide analysis. Our system uses a motorized microscope to capture cytology images, which are then processed through an AI pipeline involving image stitching, cell segmentation, and classification. We utilize the lightweight UNet-based model involving human-in-the-loop approach to train our segmentation model with minimal ROIs. CvT-based classification model, trained on the SIPaKMeD dataset, accurately categorizes five cell types. Our framework offers enhanced accuracy and efficiency in cervical cancer screening compared to various state-of-art methods, as demonstrated by different evaluation metrics.
