Using the Method of Recursion to Read and Realize the Nested Data Set of Medical Image

DICOM 3.0 is the standard for medical image.How to display the medical image is the first step of processing.And how to correctly read the nested data set is the key processes.In this paper,we analyse the data format of nested data set,and to counter the feature,we present using recursion method to read the nested data set.Experiments prove the algorithm is simple and easy to realize,and can read DICOM image correctly.It reading the nested data set correct is the key step in image processing and image analysis.This method lay a foundation for further research on medical image.
