DICOM (Digital Imaging and Communications in Medicine) files are widely used in medical imaging. The pydicom library in Python allows you to read, modify, and write DICOM files easily.
Example: Reading and Displaying a DICOM File
import pydicomimport matplotlib.pyplot as plt# Load the DICOM filefile_path = "path/to/your/file.dcm"ds = pydicom.dcmread(file_path)# Access metadataprint(f"Patient ID: {ds.PatientID}")print(f"Modality: {ds.Modality}")# Display the image (requires NumPy and Matplotlib)plt.imshow(ds.pixel_array, cmap="gray")plt.title("DICOM Image")plt.show()Copied!âś•CopyThis example reads a DICOM file, prints metadata like Patient ID and Modality, and displays the image using Matplotlib.
Key Features of pydicom
Reading DICOM Files: Use dcmread() to load DICOM datasets.
Modifying Metadata: You can edit attributes like PatientID or StudyDate directly.
Saving Changes: Save modified files using save_as().
