Monai Data Augmentation Repack Jun 2026

Modify geometry while preserving anatomical plausibility.

Modify pixel/voxel values to simulate acquisition variability. monai data augmentation

If you are still writing custom Dataset classes with scipy.ndimage rotations, it’s time to switch. Let MONAI handle the heavy lifting so you can focus on the architecture. Modify geometry while preserving anatomical plausibility

| Transform | Description | Example Use Case | |-----------|-------------|------------------| | RandGaussianNoise | Add Gaussian noise | Low-dose CT | | RandGaussianSmooth | Smooth with Gaussian kernel | Different scanner resolutions | | RandAdjustContrast | Random contrast adjustment | Varying soft tissue contrast | | RandHistogramShift | Random shift in histogram | MRI field inhomogeneity | | RandBiasField | Simulate MRI bias field | Brain MRI intensity non-uniformity | | RandGibbsNoise | Truncation artifact | Under-sampled MRI | | RandCoarseDropout | Simulate missing patches | Occlusions, motion artifacts | Let MONAI handle the heavy lifting so you
