摘要
查找表算法在数字信号处理中已有广泛的应用,但在数字减影血管造影术中的应用却报道不多。本文讨论了不同查找表算法对数字减影血管造影图像的影响。结果表明:使用不同的输出查找表算法,会得到不同效果的数字减影血管造影图像。通过分析与比较,我们认为:在图像的后处理方面,应用查找表算法可以进一步改善数字减影血管造影图像的质量。
Look-up table (LUT) algorithms have been widely used in digital signal processing, but the article on the application of LUT algorithms in digital subtraction angiography was rarely reported. In this article, the effect of different LUT algorithms on digital subtraction angiography images is introduced. The result reveals that different LUT algorithms can bring about different effects of image. Based on analysis and comparison, we deem it possible to acquire improved images of DSA by use of some LUT algorithms with image processing.
