摘　　要：考虑到人眼对颜色信息的敏感性,提出一种基于伪彩色的医学数字成像和通信(digital imaging and communications in medicine,DICOM)图像显示方法,即通过映射函数将DICOM标准图像中的65 536个灰度级映射到红-绿-蓝(RGB)颜色空间,从而以伪彩色方式显示DICOM标准图像,同时可以转化为其他图像格式。实验结果表明,DICOM标准图像中不同的区域会以不同的颜色区分,人眼可以直接有效地观察到DICOM标准图像中的许多细微差别。According to the sensitivity of human eye to color,a method for displaying digital imaging and communications in medicine(DICOM)standard image using pseudo-color was proposed.This method mapped65536gray levels to redgreen-blue(RG B)color space by map function,and then the DICOM standard image could be displayed using pseudocolor and could convert to other image formats.The experiment results show that diverse areas in the DICOM standard image can be distinguished by different color.In people5s visual,the nuances of adjacent areas in the DICOM standard image can be observed directly and effectively by human eyes.
