论文摘要

根据世界卫生组织(WHO)的数据,据估计,仅在2020年,疟疾就会造成627,000人死亡,并感染了超过2.41亿人,比2019年增加了12%。血细胞的显微镜诊断是诊断疟疾的标准测试程序。但是,这种诊断方式是昂贵的,耗时的,并且对人为错误的主观为主观,尤其是在缺乏训练有素的人员进行高质量显微镜检查的发展中国家。本文提出了质量划线(MAISCOPE):一种新型,低成本的便携式设备,可以拍摄显微镜图像,并自动检测具有嵌入式AI的疟疾寄生虫。该设备有两个子系统。第一个子系统是一个在设备上的多层深度学习网络,它从微观图像中检测到红细胞(RBC),然后是疟疾寄生虫分类器,该分类剂识别单个RBC中的疟疾寄生虫。测试和验证表明,使用Tensorflow Lite,对于检测模型的分类和平均精度的高平均精度为89.9%,同时解决了有限的存储和计算能力。该系统还具有云同步,该系统连接到Internet时将图像发送到云中,以进行分析和模型改进目的。第二个子系统是由Raspberry Pi,相机,触摸屏显示器和创新的低成本珠显微镜等组件组成的硬件。珠显微镜的评估与昂贵的光显微镜相似的图像质量相似。该设备的设计为便携式,并在没有互联网或电源的远程环境中工作。该解决方案可扩展到需要显微镜检查的其他疾病,并可以帮助标准化发展中国家农村地区疾病诊断的自动化。

According to the World Health Organization(WHO), malaria is estimated to have killed 627,000 people and infected over 241 million people in 2020 alone, a 12% increase from 2019. Microscopic diagnosis of blood cells is the standard testing procedure to diagnose malaria. However, this style of diagnosis is expensive, time-consuming, and greatly subjective to human error, especially in developing nations that lack well-trained personnel to perform high-quality microscopy examinations. This paper proposes Mass-AI-Scope (MAIScope): a novel, low-cost, portable device that can take microscopic images and automatically detect malaria parasites with embedded AI. The device has two subsystems. The first subsystem is an on-device multi-layered deep learning network, that detects red blood cells (RBCs) from microscopic images, followed by a malaria parasite classifier that recognizes malaria parasites in the individual RBCs. The testing and validation demonstrated a high average accuracy of 89.9% for classification and average precision of 61.5% for detection models using TensorFlow Lite while addressing limited storage and computational capacity. This system also has cloud synchronization, which sends images to the cloud when connected to the Internet for analysis and model improvement purposes. The second subsystem is the hardware which consists of components like Raspberry Pi, a camera, a touch screen display, and an innovative low-cost bead microscope. Evaluation of the bead microscope demonstrated similar image quality with that of expensive light microscopes. The device is designed to be portable and work in remote environments without the Internet or power. The solution is extensible to other diseases requiring microscopy and can help standardize automation of disease diagnosis in rural parts of developing nations.
