数字乳房X片中的伪彩色增强应用

The application of pseudo-color enhancement in digital mammography

利用数字图像处理中伪彩色理论 ,讨论了灰度 彩色变换函数 ,并用合适的线性变换函数对数字乳房X片进行处理。处理后的图像与原数字灰度图像相比较 ,可分辨性明显提高。可以利用这种变换 ,辅助医疗诊断 ,从而降低乳房癌的漏诊和误诊率。经验证 ,经过伪彩色增强后的数字乳房X片病灶区域的可分辨性明显优于原数字图像 。

The mapping function was discussed that converts the gray level image into colorful image by pseudo-color enhancement theory in digital image.Compared to the original gray level image,the processed pseudo-color image could be more easily distinguished.It also reduced the rate of both missed diagnosis and misdiagnose during the process of checking breast cancer.By verifying,the resolution on focus in processed pseudo-color image was much better than the original digital mammorgraphy.So the methods had a great value in clinical diagnosis.
