摘　　要：乳腺钼靶X线摄影是临床筛检早期乳腺癌的首选方法。通过对含有微钙化点钼靶X线图像的灰度分布特点进行分析,提出基于小波的反锐化掩模算法实现对钼靶X线图像的增强。实验结果表明,这种方法可以在抑制噪声的同时对图像进行有效增强,提高图像的对比度,特别是使钙化点的显示更为明显。Mammary molybdenum- target X- ray photographing is the preferred method for the early mammary glands cancer clinical screening. This paper analyzes the gray scale distribution of molybdenum - target X - ray photography with micro calcifications,and then puts forward to enhance the molybdenum - target X - ray photography by the anti - sharpening mask algorithm on wavelet. Experiment shows it can restrain noise while enhance the photographic efficiently. It can increase the contrast of the photographic and make the micro calcifications more distinct.
