摘要
本文分析了核医学图像的形成过程及特点，提出了用现代图像处理技术处理核医学图像时存在的不足。根据核医学图像的特点，给出了核医学图像的平滑对比度拉伸处理算法。最后给出了模拟冷区病灶的处理效果。
In this paper,we analyse a forming process and one of the characteristics of nuclear medical image,and point out the existed problems of nuclear medical image processing with general image processing algorithms.According to the characteristics of nuclear medical image,a contrast stretching algorithm of smoothed image is provided.At last,we give a computer simulation of the model cold focus of infection.
