喉软骨薄层横断面与可视化研究

Visualization and thin sectional anatomy of the laryngeal cartilages

目的 提供数字化可视人体有关喉软骨横断面的形态学资料和数字化可视模型 ,为影像学诊断及喉外科手术治疗提供形态学依据。方法 从第三军医大学可视化研究组采集的首例中国数字化可视人体数据集中提取会厌软骨上缘至环状软骨下缘的断层图像 ,观察喉软骨的形态结构 ,在SGI工作站上利用面绘制方法对喉软骨进行三维重建和立体显示。结果 断层图像上能清晰显示喉软骨及其骨化区 ,重建结构逼真 ,能展示喉软骨的真实面貌。结论 该数字化可视人体数据集能够较好地重建喉软骨的可视化模型 ,反映喉软骨的形态及其空间毗邻关系。该结果有望应用于喉外科手术的设计和教学。

Objective To establish digitized visible model of the laryngeal cartilages of the visible human, providing morphological data for image diagnosis and laryngectomy. Methods Cross-sectional images of fresh tissues from the Chinese visible human data set were reviewed, and the laryngeal cartilages structures data were used, the data was on a section-by-section basis. Three-dimensional computer reconstructions of the laryngeal cartilages were generated from these data by surface rendering on a SGI workstation. Results The digital images from the visible human offer unique insights into the complex anatomy and ossification of the laryngeal cartilages, the quality of the computerized 3D-reconstructed images was distinct and perfect. Conclusions The visible human data set can provide complete and accurate data. The digitized model of the laryngeal cartilages offer unique insights into the laryngeal anatomy, could be used for resident education, rehearsal of an unfamiliar surgery and for developing a new surgical approach.
