基于CT的影像组学列线图对布鲁氏菌性脊柱炎和脊柱结核的鉴别价值

Zhongguo shiyan zhenduanxue
目的基于CT的影像组学列线图鉴别布鲁氏菌性脊柱炎（BS）和脊柱结核（TBS）。方法回顾性分析2018年1月至2023年3月94例布鲁氏菌性脊柱炎及脊柱结核患者的临床资料及CT图像，按照7∶3随机分为训练集和测试集。基于训练集数据，对临床及常规CT征象进行组间差异性分析，并采用多因素logistic回归构建临床模型。基于CT图像提取影像组学特征，并筛选出最优特征计算影像组学评分（Radscore）。联合Radscore、临床特征构建联合模型并绘制列线图。采用受试者工作特征曲线下面积（AUC）、特异性 ...

Shi-tomasi角点检测算法在高压断路器机械特性测试中的应用

Gaoya dianqi
操作机构的机械特性测试可以有效诊断高压断路器的机械故障，常用的机械特性测试方法有安装直线位移传感器和角度传感器两种。这两种传感器都需要固定安装在操作机构上，不同断路器可能需要不同的工装和传感器，通用性差，并且固定安装可能会增加机械故障发生的概率。目前，利用非接触式的图像识别方法，测试高压断路器的机械行程受到研究人员的广泛关注。文中介绍了一种非接触式测量方法，在高压断路器操作机构活动拉杆位置贴具有反光功能的对角扇形标识物，利用高速相机拍摄高压断路器动作过程中标识物，采用Shi-tomasi角点检测方法 ...
