phase_enc_3d.m

3D MRI pulse sequence, with a slice selection stage followed by phase-encoded acquisition of the slice. This sequence must be called from the imaging.m context, which would provide H,R,K,G, and F.

Syntax

    fid=phase_enc_3d(spin_system,parameters,H,R,K,G,F)

Parameters

 parameters.ss_grad_amp   -  the amplitude of slice selection 
                             gradient,T/m

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

 parameters.ro_grad_amp   -  readout gradient amplitude, T/m

 parameters.ss_grad_dur   -  the duration of the slice selection 
                             gradient, seconds 

 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

 fid - k-space representation of the image
