| 摘 要： | 参考了DICOM标准附录33中灰度软拷贝显示状态对该问题的解决方案,提出了一种新的改进算法.该算法针对灰度转换子过程的内在特点,通过Bresenham算法搭建线性查找表,统一了线性和非线性变换的形式,具有高效、实用的优点.应用该算法的医学软件不仅可解决影像显示的一致性问题,还可在动态连续调节图像窗值的情况下,实时地显示DICOM医学图像,提高了阅片医生的用户体验.

| Abstract: | The paper implements the Grayscale Softcopy Presentation State specified by DICOM Supplement 33,and proposes a new improved algorithm.According to the internal characters of sub process of grayscale transform,the algorithm uses bresenham algorithm to build look up table for linear mapping.The algorithm can display real time DICOM medical images under the condition of continuously adjusting window values of them,and promotes the doctor's customer experience significantly. |
