Trajectory Extractor
Summary
Automatic k-space trajectory extraction of arbitrary MRI sequences. Works by accurately determining the encoding of the generated signal.
Work In Progress 🚧
This tool will get extended support for $T_1$ / $T_2$ weighting analysis, non-ADC trajectory samples, multi-state trajectories.

Inputs
| Input | Description |
|---|---|
sequence: Vec<InstantSeqEvent> |
List of instantaneous sequence events, typically produced by conseq |
t1: f64{:rust} |
Longitudinal relaxation time $T_1$ in seconds |
t2: f64{:rust} |
Transverse relaxation time $T_2$ in seconds |
min_mag: f64{:rust} |
Minimum magnetization magnitude threshold; states below this are pruned to control complexity vs. accuracy |
Output
A list of 4D k-space positions, returned as toolapi::TypedList::Vec4. Each entry is [k_x, k_y, k_z, tau] corresponding to the dominant magnetization pathway at each ADC readout.
