SharpParams

qsm_core::bgremove::sharp

Struct SharpParams 

Source 
pub struct SharpParams {
    pub threshold: f64,
    pub radius: f64,
    pub variant: SharpVariant,
}
Expand description

SHARP parameters. The defaults are SEPIA’s (see the module docs).

Fields§

§threshold: f64

Deconvolution (TSVD) threshold (default 0.03, SEPIA’s GUI). SharpVariant::Sepia sets the frequencies where |1 − Ŝ| ≤ threshold to 0 (SHARP.m), SharpVariant::QsmJl those where |1 − Ŝ| < threshold.

§radius: f64

Sphere radius in mm (default 4, SEPIA’s GUI, whose “voxel” label is wrong: SHARP.m takes mm). Before 2026-10-28 this followed QSM.jl (18 · min(voxel size)), and before that defaulted to 6 mm, which had no reference.

§variant: SharpVariant

The implementation to reproduce (default SharpVariant::Sepia).

Implementations§

Source§

impl SharpParams

Source

pub const QSMJL_RADIUS_VOXELS: f64 = 18.0

Source

pub fn qsmjl(grid: &Grid) -> Self

QSM.jl sharp at its own defaults on grid: SharpVariant::QsmJl, r = 18 · min(voxel size) mm, thr 0.05.
