3D打印技术作为一种新兴的快速成型技术,可通过提取不同影像学数据(CT、MRI及超声图像),经图像后处理打印出相应3D模型.其能直观、全面地展示复杂的心内解剖结构,近年来在先天性心脏病、心脏瓣膜病及心律失常等疾病的诊断与治疗中的应用日益广泛.本文就基于超声图像3D打印技术在心脏疾病诊疗中的应用现状及进展进行综述.“,”As a new rapid prototyping technology,three-dimensional(3D)printing technology can extract different imaging data(CT,MRI and ultrasound images)and print the corresponding 3D model after image processing.3D printing technology can display the complex intracardiac anatomy intuitively and comprehensively.In recent years,3D printing technology is widely used in the diagnosis and treatment of cardiac diseases,such as congenital heart disease,valvular disease and arrhythmia. This article reviews the application and progresses of 3D printing technology based on ultrasound images in the diagnosis and treatment of cardic diseases.
