Diffusion MRI — Public Tier

(3 scenes)

Full-access development tier with all data visible.

What you get

Measurements (y), ideal forward operator (H), spec ranges, ground truth (x_true), and true mismatch spec.

How to use

Load HDF5 → compare reconstruction vs x_true → check consistency → iterate.

What to submit

Reconstructed signals (x_hat) and corrected spec as HDF5.

Parameter Specifications

True spec visible — use these exact values for Scenario III oracle reconstruction.

Parameter Spec Range True Value Unit
b_value_error -3.0 – 6.0 1.5 %
eddy_current -0.5 – 1.0 0.25 voxels
gradient_direction -1.0 – 2.0 0.5 deg
susceptibility -1.0 – 2.0 0.5 voxels
