Fourth, read a series of dcm picture, and then re-write

First, the program features

　　Read a series of CT dcm picture, and then re-written to a folder

Second, the code

 Third, pay attention

　　The first sentence is grammatical in now because some do not meet specifications, but just be a warning rather than an error

Fourth, bibliography

　　"Medical image segmentation and processing" ITK manual (ie manual ITK software, official website)
