3D打印解剖模型在耳鼻喉科教学的应用
|
摘要
目的探讨3D打印技术在耳鼻喉科临床解剖教学中的应用。方法使用Mimics软件将颞骨和鼻窦CT元数据重建成三维数字模型。根据兴趣层面将模型切割为可观察内部解剖结构的子模型。利用3D打印机制作模型,将兴趣层面的CT影像打印、裁剪并与模型贴合。最后,校验解剖模型的准确度。结果成功地制作了颞骨和鼻窦的3D数字模型和3D打印模型,同时在模型截面上复合了CT影像图片,可准确、清晰地还原显示颞骨和鼻窦的内、外部的结构。结论本方法制作的解剖模型有助于医学生学习和掌握耳鼻喉科临床解剖和影像,是传统教学方法的有益补充。
Objective To apply three-dimensional( 3 D) printing techniques to the clinical anatomy teaching of otolaryngology. Methods We reconstructed the three-dimensional models of temporal bones and paranasal sinuses based on CT scan data,and divided them into sub-models according to several interested planes on CT scan. Sub-models were printed with 3 D printer. The CT images of interested planes were printed by normal printer and pasted to the appropriate sub-models. We also checked the accuracy of the anatomy models. Results We successfully made the digital and3 D printing models of temporal bones and paranasal sinuses. The CT scan images were compounded to the models.The key anatomy structures outside and inside of the temporal bone and paranasal sinuses can be shown clearly and exactly on the models. Conclusions The 3 D printing models help the medical students to understand and master the clinical anatomy and radiology knowledge of otolaryngology as a supplement for traditional teaching methods.
