QSM-CI method: AMP-PE (QSM.rs) (v1)

Year: 2026

Type: software

Abstract: Approximate Message Passing with Parameter Estimation: a probabilistic Bayesian dipole inversion. MAP estimation over the nonlinear complex-exponential forward model with a Laplace sparse-wavelet prior and a two-component Gaussian-mixture noise model, with all distribution parameters estimated automatically (tuning-free). Rust port in QSM.rs, verified against the original MATLAB (github.com/EmoryCN2L/QSM_AMP_PE) to nrmse ~1e-6 / corr ~1.0 on matched inputs. QSM-CI reconstruction method amp-pe-qsmrs.
