摘要： 提出在数字乳腺Ｘ光片中检测可疑肿块的方法。首先，介绍了逻辑滤波器的基本概念，并提出了一种改进的逻辑滤波器。使用逻辑滤波器后，输出图象在灰度直方图上表现出显著的特征，这使得对可疑肿块的分段过程变得很容易。作者用２５张乳腺Ｘ光片作为测试用例，验证了这一方法的效果。文中还将这种方法与别的边缘检测、增强方法作了比较。

Abstract: A novel method for detection of suspicious regions in digitized mammograms is presented.Firstly,logic filter is introduced, followed by a modified logic filter.Secondly,we show the distinguished charateristics of the resulting gray level histogram,which facilities the segmentation of foe suspicious mass.The performance of our method is shown using 25 digital mammogram images.A comparison with other methods is also given briefly.
