基于复用计算的三维肝脏内部可视化方法研究

虚拟肝脏手术是虚拟手术中的重要内容之一。提出了一种虚拟肝脏建模和体纹理合成方法,通过对肝脏切片数据集的预处理,样条拟合构建虚拟肝脏模型,将基于复用计算的纹理合成扩展到三维空间,应用到构建好的肝脏体上。结果表明,该方法构建的肝脏体能够较好地模拟真实的肝脏结构,绘制的肝脏软组织体纹理具有较好的合成效率和质量,对后续虚拟肝脏手术个性化研究具有一定指导意义。

Research on Solid texture synthesis of Liver soft tissue Based on Reuse calculate

The virtual liver surgery is one of the important contents in the virtual surgery. We propose a virtual liver modeling and solid texture synthesis method, by preprocessing the data set of liver slice, Spline fit to build the virtual liver model,expand the texture synthesis base on reuse calculate to the three-dimensional space,apply to the liver model which has been built.The result shows that the liver model can simulate real liver structure,the liver soft tissue solid texture has better synthesis efficiency and quality,it will have a certain guiding significance on the following study of virtual liver surgery individuation.
