This paper describes an extended ray casting scheme for three-dimensional (3-D) navigation into the heart cavities for preoperative planning using multislice X-ray computed tomography data. The key benefit is that artifacts due to contrast inhomogeneities can be eliminated during volume traversal, thus improving the visual perception of the endocardial wall.
本文描述了一种扩展的光线投射方案，用于利用多层X射线计算机断层扫描数据进行三维（3-D）心脏腔室导航，以进行术前规划。其关键优势在于，在体素遍历过程中可以消除由于对比度不均匀引起的伪影，从而改善心内膜壁的视觉感知。
