Enum EchoTime 

pub enum EchoTime {
    First,
    Last,
    Spacing,
    Sum,
    Seconds(f64),
}

Which echo time a method converts the field from ppm to radians at.

Variants

First

The first echo time, TE(1).

Last

The last echo time, TE(end).

Spacing

The echo spacing, TE(2) − TE(1) as the MEDI toolbox’s readers set delta_TE; the echo time for one echo.

Sum

The sum of the echo times, ΣTE: the phase summed over the echoes, as STI Suite’s QSM_GUI passes its combined multi-echo phase to QSM_star (its sum_TE field).

Seconds(f64)

An explicit echo time in seconds, whatever the scan’s echo times are.

Implementations

impl EchoTime

pub fn resolve(self, echo_times: &[f64]) -> Result<f64, String>

The echo time in seconds this choice picks from echo_times (seconds, in acquisition order).

Errors if the choice needs the echo times and there are none, or if the result is not a finite positive time (e.g. echoes given out of order for EchoTime::Spacing).

pub(crate) fn seconds(self, echo_times: &[f64], method: &str) -> f64

resolve for a method that has no error path: panics with method and the reason if the choice cannot be resolved. The pipeline checks first.

fn describe(self) -> &'static str
