2D phase encoding imaging pulse sequence with optional diffusion weighting during the echo time. This sequence must be called from the imaging.m context, which would provide H,R,K,G, and F.
Syntax
mri=phase_enc_2d(spin_system,parameters,H,R,K,G,F)
Arguments
parameters.t_echo - echo time, seconds
parameters.diff_g_amp - [optional] a vector of diffusion gra-
dient pair amplitudes in X,Y (T/m) to
be active during the echo time
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
