如何在Python中加载DICOM文件？

Question

I am trying to figure out the basics of importing DICOM files in Python using pydicom. While trying really simple code, I get following errors:

For code: import dicom

filePath="C:\Python34\Lib\site-packages\dicom\testfiles"
ds=dicom.read_file(filePath[0])

I get error: C:\\Python34\\python.exe C:/Users/041213/PycharmProjects/D/Deki.py Traceback (most recent call last): File "C:/Users/041213/PycharmProjects/D/Deki.py", line 4, in ds=dicom.read_file(filePath[0]) File "C:\\Python34\\lib\\site-packages\\dicom\\filereader.py", line 589, in read_file fp = open(fp, 'rb') FileNotFoundError: [Errno 2] No such file or directory: 'C'

I am using Python 3.4, pydicom 0.9.9 and JetBrains PyCharm Community Edition 2016.3.2 If anyone can help me with this, or even just help me how to load a DICOM file in general, I would appreciate it a lot.

Answer 1

you're passing the first char of the string ( C ) instead of the full string. Just do:

ds=dicom.read_file(filePath)

next error you'll stumble into: use raw prefix or \\t gets interpreted as a tabulation character:

filePath=r"C:\Python34\Lib\site-packages\dicom\testfiles"
         ^

Answer 2

Use and \\ escape character to avoid issues with tab and other special characters. Also remember when you do filePath[0] on a string it returns the first character

filePath="C:\\Python34\\Lib\\site-packages\\dicom\\testfiles"
ds=dicom.read_file(filePath)
