spin_echo.m

Gradient echo pulse sequence.

Syntax

    fid=spin_echo(spin_system,parameters,H,R,K,G,F)

Description

This sequence must be called from the imaging.m context, which would provide H,R,K,G, and F.

Arguments

     parameters.g_amp      - the amplitude of gradient T/m 

     parameters.g_step_dur - time step duration

     parameters.g_n_steps  - number of time steps

Outputs

     fid - the time domain echo signal

Examples

See spin_echo_1d.m file in examples/imaging directory
