| 摘 要： | 数字血管造影是现代可视化医疗中一种广泛应用的技术,但是心血管造影图像往往充满噪声,使得医生无法判别.传统增强技术往往难以将血管,尤其是细小的血管,从对比度低且背景复杂的造影图像中增强出来.由于血管往往具有局部空间的结构一致性,本文基于一种共圆规则融合血管上下文的信息并通过一个迭代过程使得一致性的空间成分得到增强.用该方法对血管造影图像进行处理,使血管从背景中显著突出,然后辅以适当的后续处理,便可以得到较为满意的视觉效果.

| Abstract: | Digital angiography is one of wide-using technique of visualization in modern medical treatment.However,it seems hard for doctor to diagnose cardiovascular diseases by angiograms due to noise influence.It is difficult for traditional techniques to enhance vessels,especially some distal vessels,from the angiograms with low contrast and complex background.Due to coherent configuration of vessels in local space,an angiogram enhancement method is proposed,which integrates contextual information based on a co-ci... |
