How to read and show DICOM Images using Python

DICOM (Digital Imaging and Communications in Medicine) is commonly used for storing medical imaging information. DICOM files contain both image data and header information. We can use the pydicom library to read and show the DICOM images. If you want to learn about computer vision, I strongly advise you to read This book.

Step 1: Install pydicom library

pip install pydicom

Step 2: Read and show DICOM Images

# Import the required modules
import pydicom
import matplotlib.pyplot as plt

# Read the DICOM file
file = pydicom.dcmread("file.dcm")

# Get the image data from DICOM file
data = file.pixel_array

# Display the image
plt.imshow(data, cmap="gray")
plt.show()
