Struct R2PrimeNetNorm 

Source 
pub struct R2PrimeNetNorm {
    pub r2star: (f64, f64),
    pub r2prime: (f64, f64),
    pub dr: f64,
}
Expand description

Training z-score constants for R2PRIMEnet (xsepnet_train_patch_norm_factor_inplane_largedegree_romeo_arlo.mat): each field is (mean, std), in Dr-scaled (ppm-equivalent) units. The input is normalized (r2star/dr - mean)/std; the output de-normalized (y*std + mean)*dr.

Fields§

§r2star: (f64, f64)

(mean, std) of the Dr-scaled R2* input channel.

§r2prime: (f64, f64)

(mean, std) of the Dr-scaled R2′ output channel.

§dr: f64

Relaxivity (Hz/ppm) scaling R2*/R2′ into the network’s ppm-equivalent units.

Implementations§

Source§

impl R2PrimeNetNorm

Source

pub(crate) fn r2prime_hz(&self, z: f64) -> f64
