1. 在ubuntu上安装： conda install -c conda-forge pydicom

2. 读取dicom并可视化

   import pydicom, os

   import matplotlib.pyplot as plt

   path = os.path.join(root, file)

   im = pydicom.dcmread(path)   # type of data is FileDataset

   px = im.pixel_array          # convert im to the type of numpy.ndarray

   plt.figure()

   plt.imshow(px)

   plt.show()          # do not forget this
