| 摘 要： | 目前少见到关于输出查找表算法在数字减影血管造影术中应用的报道。本文将输出查找表算法应用于数字减影血管造影术中,探讨不同输出查找表算法对数字减影血管造影图像的影响。研究表明：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,使用分段幂函数或分段指数函数可以得到比较理想的减影图像。

| Abstract: | Currently,the application of look-up table(LUT) algorithms in digital subtraction angiography were rarely reported.In this article,the output LUT algorithms have been applied to the digital subtraction angiography,and the effects of different output LUT algorithms on the images of the digital subtraction angiography were discussed.The result is that different LUT algorithms can result in different effects of DSA images.The improved DSA images can be brought with power subsection-function or exponential subs... |
