基于虚拟仿真实验教学系统的骨髓细胞学检查学习平台的构建

Construction of bone marrow cytology examination learning platform based on virtual simulation experiment teaching system

目的模拟骨髓穿刺、显微镜使用及骨髓细胞形态学检查全过程,构建骨髓细胞学检查虚拟仿真教学系统。方法通过采集高性能图像,构建立体沉浸式虚拟三维系统,开发虚拟现实交互平台,以平台为基础构架,完成虚拟仿真实验教学系统。结果建立虚拟仿真模块——骨髓穿刺、骨髓片制作、显微镜使用、正常/异常骨髓细胞形态辨别、与临床病例的对应及分析,同时搭建完善的线上学习及考核平台。结论骨髓细胞学检查虚拟仿真教学系统的构建增加了学生模拟临床锻炼的机会,使其不受时空限制,随时随地反复练习。该教学系统极具趣味性和可操作性,能提高学生的主观能动性,更好地培养出实践能力突出、综合素质优异的卓越医学人才。

Objective To construct a virtual simulation teaching system for bone marrow cytology by simulating the whole process of bone marrow puncture,microscope use and bone marrow cell morphological examination.Methods By collecting high performance images,the three-dimensional immersive virtual 3D system was constructed,the virtual reality interactive platform was developed,and the virtual simulation system was completed based on the platform framework.Results Virtual simulation modules were established,including bone marrow puncture,bone marrow slice making,microscope use,normal/abnormal bone marrow cell morphological discrimination,correspondence and analysis with clinical cases.A complete online learning and assessment platform was built.Conclusion The construction of virtual simulation teaching system of bone marrow cytology examination can make students get the opportunity of similar clinical exercise at any time,and achieve repeated practice outside the laboratory.The teaching system is very interesting and operable,can improve students'learning enthusiasm,and better train excellent medical talents with strong ability and high comprehensive quality.
