Expand description
BFRnet deep-learning background field removal (onnx feature).
BFRnet is a 3D dual-frequency octave-convolution U-Net that predicts the
background field from a masked total field; the local tissue field is
total − background, re-masked. Everything is in ppm — the network never
sees TE/B0/B0-direction. This mirrors the QSM-CI ONNX port (faithful to the
authors’ MATLAB predict to |Δ| ≈ 1e-7).
Weights are not bundled; the caller passes the exported bfrnet.onnx bytes
(see crate::models).
