摘要
在对医学三维数据场模糊特性的分析基础上 ,提出了一种提高三维医学数据场边界过渡区域图像质量的体元投射算法。论文详细说明了算法流程 ,包括特征区域的提取方法和基于体元合并的数据场绘制方法。实验表明 ,算法既提高了过渡区的图像质量 。
Existing methods for obtaining image of edge transitional region do not work well when applied to 3D medical data field. We present an algorithm that can improve image quality of edge transitional region of 3D medical data field. Section 2 explains in much detail our algorithm. Subsection2.2 defines the feature region of 3D medical data field. Subsection2.3 explains the rendering of image of data field. Subsubsection 2.3.1 focuses on cell combination. Fig. 1 shows the image obtained with our method and Fig. 2 shows the image obtained with the method of Ref.3, which is applied to 3D data but does not satisfy the special needs of 3D medical data field. The comparison of Figs.1 and 2 shows that our algorithm can improve image quality of edge transitional region of 3D medical data field.
