中文摘要：

医学图像分析和三维重建等都需要对DICOM数据进行准确的序列分析并对各序列中的切片进行正确的排序。目前尽管有很多开源库都支持对DICOM文件的读写，但对临床DICOM数据的序列分析与切片排序存在很多问题。本文分析了在GDCM开源库的基础上研究DICOM数据的序列分析与切片排序时遇到的问题，并提出了解决方案。

英文摘要：

Accurately analyzing sequences （ or volumes） of clinical DICOM data and sorting the slices in each volume is a prerequisite for medical image analysis and three-dimensional （3D） reconstruction. There are many open sources with DICOM data read-write function. However these open libraries have many sorting and sequence analysis problems when they are applied to real clinical DICOM data. We analyzed the problems with the GDCM open libraries and proposed our solutions, which have been validated by real clinical data with reliable results.
