Read and Write Medical Data

Read, write, and manipulate medical imaging data in MATLAB. This skill covers both Image Processing Toolbox (IPT) functions and Medical Imaging Toolbox (MIT) enhanced APIs.

When to Use

• Reading or writing DICOM, NIfTI, or NRRD files
• Listing DICOM series with dicomCollection
• Extracting spatial referencing or coordinate transforms
• Changing volume orientation or extracting oriented slices
• Working with DICOM RT structures (contours, masks, modify/write)
• Anonymizing DICOM data

When NOT to Use

• Displaying or visualizing volumes (use matlab-display-volume skill)
• Displaying 2-D medical images with annotations (use matlab-display-image skill)
• Reading non-medical image formats (PNG, TIFF, JPEG) — use imread
