摘要
从DSA(Digital Subtraction Angiography,数字减影血管造影)医学图像的特点出发,提出了在实现DSA减影时,减影前先进行对数变换,减影后再进行单阈值分割的解决方案来增强血管信息。该方案已用Delphi具体软件实现,图像效果符合医学诊断的要求,得到了医学专家的充分肯定。
By the analysis of characteristics of DSA medical image, a solution to the blood vessel information enhancement is provided based on the application of DSA subtruction. Logarithm transformation is used before the subtraction, and threshold segmentation technology is applied after the subtraction. The method has been realized in Delphi program. The results suit the request of medical diagnose, and the medical experts give high score on the effect of it.
