The Internet of Things (IoT), big data, and artificial intelligence (AI) are all key technologies that influence the formation and implementation of digital medical services. Building Internet of Medical Things (IoMT) systems that combine advanced sensors with AI-powered insights is critical for intelligent medical systems. This paper presents an IoMT framework for brain magnetic resonance imaging (MRI) analysis to lessen the unavoidable diagnosis and therapy faults that occur in human clinical settings for the accurate detection of cerebral microbleeds (CMBs). The problems in accurate CMB detection include that CMBs are tiny dots 5-10 mm in diameter; they are similar to healthy tissues and are exceedingly difficult to identify, necessitating specialist guidance in remote and underdeveloped medical centers. Secondly, in the existing studies, computer-aided diagnostic (CAD) systems are designed for accurate CMB detection, however, their proposed approaches consist of two stages. Potential candidate CMBs from the complete MRI image are selected in the first stage and then passed to the phase of false-positive reduction. These pre-and post-processing steps make it difficult to build a completely automated CAD system for CMB that can produce results without human intervention. Hence, as a key goal of this work, an end-to-end enhanced UNet-based model for effective CMB detection and segmentation for IoMT devices is proposed. The proposed system requires no pre-processing or post-processing steps for CMB segmentation, and no existing research localizes each CMB pixel from the complete MRI image input. The findings indicate that the suggested method outperforms in detecting CMBs in the presence of contrast variations and similarities with other normal tissues and yields a good dice score of 0.70, an accuracy of 99 %, as well as a false-positive rate of 0.002 %. © 2017 Elsevier Inc.

物联网(IoT)、大数据和人工智能(AI)都是影响数字医疗服务形成和实施的关键技术。构建将先进传感器与人工智能驱动的见解相结合的医疗物联网(IoMT)系统对于智能医疗系统至关重要。本文提出了一种用于脑磁共振成像(MRI)分析的IoMT框架,以减少在人类临床环境中不可避免出现的诊断和治疗失误,从而准确检测脑微出血(CMB)。准确检测CMB存在的问题包括:CMB是直径为5 - 10毫米的微小斑点;它们与健康组织相似,极难识别,这使得偏远和不发达医疗中心需要专家指导。其次,在现有研究中,计算机辅助诊断(CAD)系统是为准确检测CMB而设计的,然而,它们提出的方法包括两个阶段。在第一阶段从完整的MRI图像中选择潜在的候选CMB,然后进入减少假阳性阶段。这些预处理和后处理步骤使得难以构建一个完全自动化的CMB CAD系统,该系统可以在无需人工干预的情况下产生结果。因此,作为这项工作的一个关键目标,提出了一种基于端到端增强型UNet的模型,用于IoMT设备的有效CMB检测和分割。所提出的系统在CMB分割时不需要预处理或后处理步骤,并且没有现有研究从完整的MRI图像输入中定位每个CMB像素。研究结果表明,所提出的方法在存在对比度变化以及与其他正常组织相似的情况下检测CMB方面表现出色,获得了0.70的良好骰子系数、99%的准确率以及0.002%的假阳性率。© 2017爱思唯尔公司。保留所有权利。
