摘要

冠状动脉对人类心脏的正常功能至关重要。然而,它们通常很难从其他充满血液的心脏腔中分离出来。造成这些困难的主要原因是缺乏足够的空间分辨率和局部体积效应。在本文中,我们提出了一种方法来标记冠状动脉的虚拟内镜穿越。与外部视图或切片检查方法相比,虚拟内窥镜可以更容易地视觉识别血管。此外,我们使用这种标记作为支架的冠状动脉的实际分割。

Scaffolding-based segmentation of coronary vascular structures
The coronary arteries are essential for the proper function of the human heart. However, they are generally difficult to segment in volume datasets separately from the other blood-filled cavities of the heart. The major reason for these difficulties is the lack of sufficient spatial resolution and partial volume effects. In this paper, we present a method to mark the coronary arteries by a virtual endoscopic traversal. Virtual endoscopy enables a significantly easier visual identification of the blood vessels in comparison to outside views or slice-by-slice examination methods. Furthermore, we use this marking as a scaffold for the actual segmentation of the coronary arteries.
