摘要 影像组学是从CT、MRI、PET等医学影像的ROI提取大量影像特征,来描述肿瘤生物学特征和异质性等信息的一种定量分析方法。随着数据科学发展,影像组学的研究方法日益受到国内外的重视。影像组学的特征提取是其中的重要步骤。本文对影像组学的特征提取进行综述。 Radiomics refers to the comprehensive quantification of information such as tumor biological feature and heterogeneity through assessing a large number of quantitative image features from ROI of CT, MRI and PET images. With the development of data science, radiomics has been paid more and more attention. Feature extraction is an important step of Radiomics. The processes in feature extraction of radiomics were reviewed in this paper.
