| # OpenBrain v1.0 reviewer sample |
|
|
| This directory contains the public reviewer sample for OpenBrain v1.0. |
| It is intended for quick inspection without downloading the full release. |
|
|
| ## Contents |
|
|
| - `sample_manifest.csv`: metadata and QC-7 values for the sample. |
| - `cases/<case_id>/image.nii.gz`: preprocessed T1-weighted image. |
| - `cases/<case_id>/brain_mask.nii.gz`: SynthStrip-derived brain mask. |
| - `cases/<case_id>/whole_brain_segmentation.nii.gz`: released automated |
| whole-brain segmentation. |
|
|
| The sample contains 64 source-diverse cases. All sample cases are drawn |
| from the HighConf tier and were selected by low combined risk `R`, with |
| Q1/Q3/Q4 visual-cleanliness tie-breaks. The sample is therefore designed |
| to show high-confidence examples for reviewer preview and smoke testing. |
|
|
| These labels are algorithmic pseudo-labels, not manual ground truth, and |
| should not be used for clinical decision-making. |
