摘要
通过光线投射(Ray-casting)算法中等值面、最大密度映射和合成等三种体绘制方法实现CT图像的三维重建,验证并比较这三种方法在人体模型三维重建的技术上的优缺点。结果表明VTK用于CT图像的三维可视化具有快速、方便、高效的特点,三种方法各有侧重点,实际应用中不同的需要应选用不同的方法。
CT image has been reconstructed respectively by the IsosurfaceFunction, MIPFunction （ Maximum Intensity Projection） and CompositeFunction in Ray - casting algorithm. The advantages and disadvantages of these three functions in the 3D reconstruction were validated and compared. The result indicated that the VTK approach of 3D visualization has fast, convenience and high efficiency, and the usage of them should be depended on the application.
