A new application of teaching anatomy includes the use of computed tomography angiography (CTA) images to create clinically relevant three-dimensional (3D) printed models. The purpose of this article is to review recent innovations on the process and the application of 3D printed models as a tool for using under and post-graduate medical education.
Images of aortic arch pattern received by CTA were converted into 3D images using the Google SketchUp free software and were saved in stereolithography format. Using a 3D printer (Makerbot), a model mode polylactic acid material was printed.
A two-vessel left aortic arch was identified consisting of the brachiocephalic trunk and left subclavian artery. The life-like 3D models were rotated 360° in all axes in hand.
The early adopters in education and clinical practices have embraced the medical imaging-guided 3D printed anatomical models for their ability to provide tactile feedback and a superior appreciation of visuospatial relationship between the anatomical structures. Printed vascular models are used to assist in preoperative planning, develop intraoperative guidance tools, and to teach patients surgical trainees in surgical practice.
解剖学教学的一项新应用包括使用计算机断层扫描血管造影（CTA）图像来创建具有临床相关性的三维（3D）打印模型。本文旨在回顾3D打印模型作为一种用于本科及研究生医学教育工具的制作过程和应用方面的最新创新。
使用谷歌SketchUp免费软件将CTA获取的主动脉弓模式图像转换为3D图像，并保存为立体光刻格式。使用3D打印机（Makerbot）打印出模型模式的聚乳酸材料。
确定了一种由头臂干和左锁骨下动脉组成的双血管左主动脉弓。逼真的3D模型在手中可以在所有轴向上旋转360°。
教育和临床实践中的早期采用者已经接受了医学影像引导的3D打印解剖模型，因为它们能够提供触觉反馈，并能更好地理解解剖结构之间的视觉空间关系。打印的血管模型用于协助术前规划、开发术中指导工具，并在外科手术实践中向外科实习医生传授相关知识。
