Struct HomogeneityParams 

pub struct HomogeneityParams {
    pub sigma_mm: f64,
    pub nbox: usize,
}

Parameters for inhomogeneity correction (bias field removal).

Not used by makehomogeneous, which takes sigma_mm and nbox directly; the pipeline config carries them as masking.homogeneity_sigma_mm / masking.homogeneity_nbox (defaults 7.0 and 15, MriResearchTools’ defaults) for the host to apply.

Fields

sigma_mm: f64

Gaussian smoothing sigma in mm (default: 7.0)

nbox: usize

Boxes per dimension for the boxsegment tissue segmentation, makehomogeneous‘s nbox (default: 15, MriResearchTools’). Not the number of box-filter passes of the smoothing.

Measured on the EMTP travelling heads (bridge run 1; #314): the earlier default of 3 left echo 1 visibly uneven, with a large dark centre on a GE MR750 (in-brain coefficient of variation 0.429, against 0.114 with 15 and 0.116 with N4; Philips Achieva 0.152 / 0.098 / 0.103). With 15 the image matches N4’s; BET masks moved by at most 1.4 % in volume, and on GE agreed better with HD-BET.
