摘要
为了解决医学图像处理过程中在需要频繁改变窗宽、窗位的情况下图像不能实时显示,显示过程存在明显迟滞的问题,分析了DICOM医学图像的显示过程以及传统显示过程中可以改进的地方,提出了使用统一LUT(Look Up Table)的方法来提高显示效率的解决方法,并使用Bresenham算法改进了传统的LUT的生成算法。实验结果表明该改进后的算法能提高医学影像的显示效率。
To improve display speed of DICOM medical image with continuously adjusting window values, this paper describes the transformation of manufacturer dependent pixel values of DICOM medical image into pixel values that are meaningful for display, and proposes a solution using LUT. Finally, the Bresenham algorithm is proposed to improve the LUT generation algorithm. A good result is got and an affirmation from doctors is made in practice.
