摘要
由于不同厚度的组织对射线的吸收程度不同,使得在同一幅图像中很难清晰地显示所有的解剖细节,常出现图像有过亮或过暗的部分。针对这个问题,提出了自适应反S变换算法。实验证明,该算法能对图像的过亮和过暗区域进行均衡处理,使细节更加突出。
On account of different thickness of tissues absorbing different doses of X ray, it is difficult to display anatomical details of different tissues on a single screen of DR equipment. In order to resolve this problem, the self-adaptive reverse S mode transformation algorithm is presented in the paper, which can modify darker regions and brighter regions respectively, and improve the visibility of weakly details.
