Objective To explore the eect of 3D laparoscopic assisted on the learning eect of students in clinical teaching.Methods A total of 56 students were divided into control group and observation group,each with 5 years of undergraduate internship and training doctors.e control group was taught by traditional teaching methods.e observation group was treated with 3D laparoscopic assisted teaching.e two groups were 120 minutes.Compare the two groups of students to master the knowledge of the situation and the evaluation of the two teaching methods.Resultse teaching results and satisfaction degree of the 3D laparoscopic assisted teaching group were signicantly better than those of the traditional teaching group(91.6±4.5)and(80.5±4.8),respectively.e dierence was statistically signicant(t=2.18,P<0.05).Conclusionrough advanced 3D laparoscopic assisted surgery,students can provide real,image,vivid,comprehensive disease related image information,improve students'interest in learning,but also make it easier for students to understand the clinical knowledge. 展开更多

近邻点的正确选取是正确重建表面的前提。本文基于对膝关节导航手术中扫描数据的分析,得到扫描数据特征,利用这些特征寻找近邻点,生成局部切平面,建立有向距离场。再根据Delaunay三角剖分等相关理论,提取等值面,最后生成膝关节表面模型... 近邻点的正确选取是正确重建表面的前提。本文基于对膝关节导航手术中扫描数据的分析,得到扫描数据特征,利用这些特征寻找近邻点,生成局部切平面,建立有向距离场。再根据Delaunay三角剖分等相关理论,提取等值面,最后生成膝关节表面模型。本文工作为增强膝关节导航手术的操作性和可视化效果提供了有利工具。 展开更多
