本文提出了一种精确和鲁棒的三维脑CT-DSA使用刚性配准和骨屏蔽颅内动脉瘤的早期诊断和治疗计划。我们的方法由以下四个步骤组成。首先，使用3D边缘检测技术选择颅底内的一组特征点。其次，构造了一个局部加权的3D距离图，以使我们的相似性度量鲁棒地收敛到最大值。第三，特征点之间的相似性度量是通过选择性互相关反复评估。第四，进行骨掩蔽以完全去除骨。实验结果表明，该方法的准确性和鲁棒性明显优于传统方法。特别是，我们的方法可以用于颅内动脉瘤的早期诊断和治疗计划。
This paper proposes an accurate and robust three-dimensional brain CT-DSA using rigid registration and bone masking for early diagnosis and treatment planning of intracranial aneurysms. Our method is composed of the following four steps. First, a set of feature points within skull base are selected using a 3D edge detection technique. Second, a locally weighted 3D distance map is constructed for leading our similarity measure to robust convergence on the maximum value. Third, the similarity measure between feature points is evaluated repeatedly by selective cross-correlation. Fourth, bone masking is performed to completely remove bones. Experimental results show that the accuracy and robustness of our method are much better than conventional methods. In particular, our method can be useful for the early diagnosis and treatment planning of intracranial aneurysms.
