Struct FitPpmComplexResult 

pub struct FitPpmComplexResult {
    pub field: Vec<f64>,
    pub noise: Vec<f64>,
    pub phase0: Vec<f64>,
    pub relres: Vec<f64>,
    pub echo_spacing: f64,

Output of fit_ppm_complex. Each map has one value per voxel.

Fields

field: Vec<f64>

Field as phase accrued per echo spacing (radians), wrapped to [-π, π]: it still needs spatial unwrapping. Divide by Self::echo_spacing for rad/s. Sign: that of the input phase (it increases with TE for a positive field), the convention of QSM.rs’s other field maps. MATLAB’s p1 is minus this, because Fit_ppm_complex.m fits conj(M).

noise: Vec<f64>

A priori standard deviation of Self::field, radians per echo spacing (dp1, which MEDI passes on as N_std). Depends only on the echo magnitudes; 0 where the fit is undefined. Same as fit_ppm_complex_noise.

phase0: Vec<f64>

Fitted phase at the first echo (radians, not wrapped). MATLAB’s p0 is minus this.

relres: Vec<f64>

Relative residual Σₑ|Sₑ − Ŝₑ|² / Σₑ|Sₑ|² (relres); 0 where undefined.

echo_spacing: f64

The echo spacing the field is per (s): TE₂ − TE₁, or TE₁ for a single echo, which is how MEDI’s readers set delta_TE.

iterations: usize

Gauss-Newton iterations run (the same for every voxel, as in the reference).
