Virtual Simulation Method Medical Anatomy Under the Light Shade

提出基于光线跟踪和改进离散矢量的虚拟医学解剖仿真方法,采用光线跟踪方法描述三维医学解剖实体的空间位置和形状信息,通过表面结构中的不同体素的三维坐标运算不同点的法向量,获取更为精细的解剖实体细节特征,模拟真实的光照环境,采用改进离散矢量方法塑造解剖实体的虚拟仿真模型,完成解剖虚拟仿真。实验数据表明,该种仿真方法获取的虚拟解剖图比传统方法更为直观、精确,并且具有较高的仿真效率和精度。

Proposed based on ray-tracing and improve virtual medical anatomy of the simulation method of discrete vector, ray tracing method is used to describe the three dimensional medical anatomical entity space location and shape in- formation, through the surface structure of the 3 d coordinates of different voxel operational differences between the normal vector, obtain more elaborate anatomical entity details characteristics, simulate real light environment, with the improved method of discrete vector shape anatomy virtual simulation model of entity, complete the anatomy of the virtual simulation. Experimental data show that this simulation method to get the virtual anatomy of more intuitive and accurate than traditional methods, and has high simulation accuracy and efficiency.
