摘要
计算机X线摄影(CR)是应用最为广泛的辅助医学诊断的手段。然而在CR摄影中,有时会产生条状的滤线栅伪影,影响图像质量。重点研究和讨论了各种滤波方法,并对其效果一一作出评价,寻找一种合适的方法既能够去除滤线栅形成的伪影,又能够保留原X光片上的细节和病灶。经过大量实验验证,最终确定的滤波方法效果比较好,具有广泛实际的应用前景。
Computed radiography (CR) is one of the diagnosis. However, there are some strip artifacts in most widely used methods of complementary important the CR Photography. They are the shadows of anti-scattering grid voted in the imaging plate. They affect the pictures' quality. In this paper, we principally discuss the different filters, and evaluate their effects, to find a suitable method to remove the anti-scattering grid artifact, more over retain the details in the original X-ray films. After a large number of experiments, the effect of the method in this paper is better to solve this problem and is useful for the practical application.
