Struct PhaseOffsetRemoval 

pub struct PhaseOffsetRemoval {
    pub phases: Vec<Vec<f64>>,
    pub offset: Vec<f64>,
    pub valid: Vec<u8>,
}

Result of phase_offset_removal (MCPC-3D-S on coil-combined echoes).

Fields

phases: Vec<Vec<f64>>

The offset-corrected phase per echo, wrapped to [-π, π]; NaN wherever the offset is undefined (valid == 0), as in MriResearchTools’ mcpc3ds.

offset: Vec<f64>

The smoothed phase offset; NaN where it is undefined.

valid: Vec<u8>

1 where the smoothed offset is defined: MCPC-3D-S’s own robustmask of sqrt(|HIP|) plus the margin the masked smoothing extrapolates into. Only these voxels carry a phase the field can be estimated from; restrict every later step to them (the pipeline returns brain mask ∩ valid as FieldMappingResult::valid_mask).

Implementations

impl PhaseOffsetRemoval

pub fn excluded_from(&self, mask: &[u8]) -> usize

Number of voxels of mask outside valid.

Trait Implementations

impl Clone for PhaseOffsetRemoval

fn clone(&self) -> PhaseOffsetRemoval

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PhaseOffsetRemoval

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
