2D phase encoding imaging pulse sequence.

Syntax

    mri=phase_enc(spin_system,parameters,H,R,K,G,F)

Description

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

Arguments

 parameters.t_echo        -  echo time, seconds

 parameters.pe_grad_amp   -  phase encoding gradient amplitude, T/m
 
 parameters.ro_grad_amp   -  readout gradient amplitude, T/m

 parameters.pe_grad_dur   -  the duration of the phase encoding 
                             gradient, seconds 

 parameters.ro_grad_dur   -  the duration of the readout gradient,
                             seconds

 parameters.image_size    -  number of points in each dimension of
                             the resulting image

Outputs

 mri - MRI image with square sinebell apodisation
