The main problem with converting DICOM images to PNG is that the DICOM image format is not a standard image format. Many programs that can convert DICOM images to other formats cannot do so with PNGs.
import pydicom
import matplotlib.pyplot as plt
ds = pydicom.dcmread('filename.dcm') # read dicom image
image = ds.pixel_array # get image array
plt.imshow(image, cmap=plt.cm.bone) # plot image using matplotlib
This code imports the pydicom and matplotlib.pyplot libraries, reads in a dicom image from a file, and displays the image using matplotlib.

png and images
In Python, images are represented by the image module. Images can be read from files or loaded from memory.
To create an image in Python, you can use the Image() function. This function takes two arguments: the width and height of the image in pixels, and a file name or memory address where the image data is stored.
The following code creates an image named myimage with dimensions 512×512 pixels and stores the image data in memory at address 0x100000:
import Image myimage = Image(512, 512) myimage.save(“myimage.png”)
