摘    要:目的:探讨利用K—medoids聚类分析方法来寻找典型病理图像。方法:对正常、低度和高度鳞状上皮内病变宫颈细胞的51个特征参数进行标准化处理,以消除原始变量数量及量纲影响。运用统计软件R对所有特征参数进行K—medoids聚类分析。结果:对于正常、低度和高度鳞状上皮内病变宫颈细胞的分类正确率分别为91.7%、98.0%和92,0%。作为类中心点的3个病理图片可作为典型病理图片指导临床及教学研究。结论:该方法简单、方便,客观性强,可应用到其他医学领域定量研究。

关 键 词:K.medoids聚类  典型图像

Abstract:Objective: To investigate the potentiality of K-medoids cluster analysis in searching typical pathological images.Methods: All 51 characters of the samples from normal cervical cells,cervical cells in low-grade squamous intraepithelial lesion(LSIL),and cervical cells in high-grade squamous intraepithelial lesion(HSIL) were standardized for eliminating the influence of the size and dimension of original variables.Statistical software R was used to conduct K-medoids cluster analysis.Results: The diagnostic accuracy of normal,LSIL,and HSIL cervical cells were 91.7%,98.0%,92.0%,respectively.The medoids identified from each cluster can be used as typical images for teaching and research.Conclusion: K-medoids cluster analysis is an easy,convenient,objective method for searching typical pathological images and can be used in medical quantitative studies.
Keywords:K-medoids clustering   typical image
