论文摘要
基于CT图像的胃诊断是作为一种诊断方法的新方法。虚拟展开的（VU）视图适合显示其墙壁。在本文中，我们提出了一种半自动化的方法来产生胃VU视图。我们的方法需要最少的手动操作。确定展开力量和终止展开过程是自动化的。根据其半径估算胃的展开形状。确定展开的力，以使胃壁变形为预期的形状。如果变形形状和预期形状之间的形状差很小，则迭代变形过程将终止。我们使用67个CT体积的实验表明，我们提出的方法可以为76.1％的病例产生良好的VU视图。
CT image-based diagnosis of the stomach is developed as a new way of diagnostic method. A virtual unfolded (VU) view is suitable for displaying its wall. In this paper, we propose a semi-automated method for generating VU views of the stomach. Our method requires minimum manual operations. The determination of the unfolding forces and the termination of the unfolding process are automated. The unfolded shape of the stomach is estimated based on its radius. The unfolding forces are determined so that the stomach wall is deformed to the expected shape. The iterative deformation process is terminated if the difference of the shapes between the deformed shape and expected shape is small. Our experiments using 67 CT volumes showed that our proposed method can generate good VU views for 76.1% cases.
