3D MRI pulse sequence, with a slice selection stage followed by phase-encoded acquisition in the slice selected.

==Syntax==

mri=slice_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.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

parameters.gs_ampl - direction of the slice selection
gradient, a three-element unit vector

parameters.gp_ampl - direction of the phase encoding
gradient, a three-element unit vector

parameters.gr_ampl - direction of the readout gradient,
a three-element unit vector

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

==Outputs==

mri - MRI image of the slice with square sine bell apodisation
in the k-space.

==Examples==
See phase_enc_3d.m file in examples/imaging directory.

==Notes==
This function benefits significantly from [[Appendix F: expert-level options#NVidia Tesla coprocessor support|GPU processing]].
