Synthetic MRI dataset
Created with NV-Generate-CTMR, by running the rflow-mr-brain model.
Variants
Sample
The sample/ directory contains generated 3D brain MRI NIfTI images for T1, T2, FLAIR, and SWI modalities.
It includes both whole-brain images and skull-stripped images:
| Folder | Description |
|---|---|
sample/mri_t1/ |
T1 whole-brain MRI |
sample/mri_t2/ |
T2 whole-brain MRI |
sample/mri_flair/ |
FLAIR whole-brain MRI |
sample/mri_swi/ |
SWI whole-brain MRI |
sample/mri_t1_skull_stripped/ |
T1 skull-stripped brain MRI |
sample/mri_t2_skull_stripped/ |
T2 skull-stripped brain MRI |
sample/mri_flair_skull_stripped/ |
FLAIR skull-stripped brain MRI |
sample/mri_swi_skull_stripped/ |
SWI skull-stripped brain MRI |
Each folder contains 100 generated images. The whole-brain and skull-stripped samples were generated in separate runs, using the corresponding rflow-mr-brain modality ids for each run.
Default FOV 256/128
The default_fov_256_128/ directory contains generated 3D brain MRI NIfTI images for T1, T2, FLAIR, and SWI modalities. It uses the recommended MR brain FOV presets from the NV-Generate-CTMR inference guide, with voxel dimensions set to 256 x 256 x 128 for axial scans, 128 x 256 x 256 for sagittal scans, and 256 x 128 x 256 for coronal scans.
It includes both whole-brain images and skull-stripped images:
| Folder pattern | Description |
|---|---|
default_fov_256_128/whole_brain/<modality>/<plane>/ |
Whole-brain MRI |
default_fov_256_128/skull_stripped/<modality>/<plane>/ |
Skull-stripped brain MRI |
Each leaf folder contains 100 generated images. T1, T2, and FLAIR are provided for axial, sagittal, and coronal planes. SWI is provided for axial scans only, matching the inference guide warning that SWI sagittal and coronal training coverage is very limited.
