摘要:

文题释义:
3D打印:又称为增材制造,从工业制造到当前应用于医学,是一项极具开创性的技术,被称为第三次工业革命的主要标志之一。在医学3D打印中,主要是基于影像数据进行三维重建,利用各种金属、聚合物和光敏树脂等原材料,分别通过逐层堆积的方式构建实体,是快速成型技术的一种。
图像分割:即有目的性地提取感兴趣区域并分割成若干部分,是医学影像到3D打印的关键分析步骤,根据操作过程不同主要将其分为自动分割、手动分割以及半自动分割技术。分割方法主要包括阈值法、区域法、边缘法、直方图法4种,最常用的是阈值分割法,实际应用时常常几种方法混合使用。

背景:3D打印作为影像技术“实体化”的延伸,两者之间密不可分。为了满足临床应用需求,不同成像原理的影像技术与3D打印结合使得其在医学应用上有了更多可能。
目的:总结不同成像原理影像技术与3D打印结合在医学方面应用的研究进展,并对其优缺点进行综述分析。
方法:在Web of science、PubMed、CNKI、SinoMed及万方数据库,使用主题词“3D printed,Three-dimensional printing,Additive Manufacturing,Ultrasonography,Ultrasound,MRI,Magnetic Resonance Imaging,CT,Computed Tomography,PET/CT,SPECT/CT,Radiotherapy,Digital Subtraction,DSA,3D 打印,超声检查,磁共振成像,放疗,核医学”等检索近5年内相关文献,最终纳入61篇进行综述。
结果与结论:①基于不同类型影像数据的3D打印医学应用主要分为临床应用、设备应用及教学应用,讨论不同影像数据源的优缺点,并概述了当前不同影像技术与3D打印结合应用的难点;②目前医学3D打印技术基于放射原理成像成型的临床应用较广,并且使用相对成熟;③而随着3D打印技术应用的深入,非电离成像方式MRI、超声也在应用中展现出较大潜力。

Abstract: BACKGROUND: As an extension of the “materialization” of image technology, three-dimensional (3D) printing is inseparable between the two. To meet the needs of clinical application, the combination of different principles of imaging technology and 3D printing technology makes it more possible in medical application. 
OBJECTIVE: To summarize the progress of medical application research of the combination of different imaging principles and 3D printing, and analyze its advantages and disadvantages.
METHODS: The relevant articles from the databases of Web of Science, PubMed, CNKI, SinoMed and Wanfang were searched by computer. The subject headings “3D printed, Three-dimensional printing, Additional Manufacturing, Ultrasonography, Ultrasound, MRI, Magnetic Resonance Imaging, CT, Computed Tomography, PET/CT, SPECT/CT, Radiotherapy, Digital Subtraction, DSA” in English and “3D printing, ultrasound, MRI, radiotherapy, nuclear medicine” in Chinese were retrieved in the past five years, and finally 61 articles were included for review. 
RESULTS AND CONCLUSION: (1) This paper summarizes the medical application of 3D printing based on different types of image data, which is mainly divided into clinical application, equipment application and teaching application. The advantages and disadvantages of different image data sources are discussed and the difficulties in the combination of the two are summarized. (2) At present, the clinical application of medical 3D printing based on radiological imaging is wide, and the use is relatively mature. (3) With the in-depth application of 3D printing technology, non-ionized imaging methods such as MRI and ultrasound also show great potential in the application.
