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
