In pulmonary angiography, the heartbeat creates artifacts that hinder extraction of blood vessel images in digital subtraction angiography. Remasking according to the cardiac phase of the angiogram may be effective but has yet to be automated. Here, automatic remasking was developed and assessed ...

数字减影血管造影(digital subtraction angiography,DSA) DSA是基于顺序图像的数字减影,将未造影的图像和造影后图像分别经影像增强器增强,摄像机扫描而矩阵化,经模/数转换成数字化,两者相减而获得数字化图像,最后复经数/模转换成减影图像,此即DSA技术。该技术主要优点是图像中没有原来的骨与软组织影,故显示清楚,因其...

Digital subtraction angiography (DSA) is an alternative method for imaging the cerebral vasculature. Intravenous DSA is used primarily for evaluating the common carotid bifurcation. The superior image quality of arterial DSA makes it more suitable for studying intracranial arteriovenous malformations, aneurys...
A generalized framework for histogram-based similarity measures is presented and applied to the image-enhancement task in digital subtraction angiography (DSA). The class of differentiable, strictly convex weighting functions is identified as suitable weightings of histograms for measuring the degree of ...
