Medical three-dimensional (3D) digital reconstruction and printing have become common tools in medicine, but few undergraduate medical students understand its whole process and teaching and clinical application. Therefore, we designed an elective course of 3D reconstruction and printing for students and studied its significance and practicability.
Thirty undergraduate medical students in their second-year of study volunteered to participate in the course. The course started with three lessons on the theory of 3D digital reconstruction and printing in medicine. The students were then randomly divided into ten groups. Each group randomly selected its own original data set, which could contain a series of 2D images including sectional anatomical images, histological images, CT and MRI. Amira software was used to segment the structures of interest, to 3D reconstruct them and to smooth and simplify the models. These models were 3D printed and post-processed. Finally, the 3D digital and printed models were scored, and the students produced brief reports of their work and knowledge acquisition and filled out an anonymous questionnaire about their study perceptions.
All the students finished this course. The average score of the 30 students was 83.1 ± 2.7. This course stimulated the students' learning interest and satisfied them. It was helpful for undergraduate students to understand anatomical structures and their spatial relationship more deeply. Students understood the whole process of 3D reconstruction and printing and its teaching and clinical applications through this course.
It is significant and necessary to develop this course for undergraduate medical students.
医学三维（3D）数字重建与打印已成为医学领域常用工具，但很少有本科医学生了解其全过程以及教学与临床应用。因此，我们为学生设计了一门3D重建与打印选修课，并研究其意义和实用性。
30名本科二年级医学生自愿参加该课程。课程首先进行了三节关于医学3D数字重建与打印理论的课程。然后将学生随机分成十组。每组随机选择自己的原始数据集，该数据集可能包含一系列二维图像，包括断层解剖图像、组织学图像、CT和MRI。使用Amira软件对感兴趣的结构进行分割、3D重建，并对模型进行平滑和简化。这些模型进行3D打印并进行后处理。最后，对3D数字模型和打印模型进行评分，学生撰写关于其工作和知识获取的简要报告，并填写一份关于其学习感受的匿名问卷。
所有学生都完成了这门课程。30名学生的平均成绩为83.1±2.7。该课程激发了学生的学习兴趣并使他们感到满意。有助于本科学生更深入地理解解剖结构及其空间关系。学生通过该课程了解了3D重建与打印的全过程及其教学与临床应用。
为本科医学生开设这门课程具有重要意义和必要性。
