We propose a navigation-based computer aided diagnosis (CAD) system for the colon. When diagnosing the colon using virtual colonoscopy (VC), a physician makes a diagnosis by navigating (flying-through) the colon. However, the viewpoints and the viewing directions must be changed many times because the colon is a very long and winding organ with many folds. This is a time-consuming task for physicians. We propose a new navigation-based CAD system for the colon providing virtual unfolded (VU) views, which enables physicians to observe a large area of the colonic wall at a glance. This system generates VU, VC, and CT slice views that are perfectly synchronized. Polyp candidates, which are detected automatically, are overlaid on them. We applied the system to abdominal CT images. The experimental results showed that the system effectively generates VU views for observing colon regions.
我们提出了一种用于结肠的基于导航的计算机辅助诊断（CAD）系统。在使用虚拟结肠镜检查（VC）诊断结肠时，医生通过在结肠中导航（穿行）来进行诊断。然而，由于结肠是一个非常长且蜿蜒曲折、有许多褶皱的器官，必须多次改变视点和观察方向。这对医生来说是一项耗时的任务。我们提出了一种新的用于结肠的基于导航的CAD系统，该系统提供虚拟展开（VU）视图，使医生能够一眼观察到大面积的结肠壁。该系统生成完美同步的VU、VC和CT切片视图。自动检测到的息肉候选物会叠加在这些视图上。我们将该系统应用于腹部CT图像。实验结果表明，该系统能够有效地生成用于观察结肠区域的VU视图。
