Slice selection diagnostics function that executes a shaped pulse on the user-supplied 1D phantom and records a 1D image; it must be called from the imaging.m context, which provides H,R,K,G, and F.
Syntax
fid=slice_select_1d(spin_system,parameters,H,R,K,G,F)
Parameters
parameters.ss_grad_amp - the amplitude of slice selection
gradient,T/m
parameters.rf_frq_list - a vector of RF frequencies at each
pulse slice, Hz
parameters.rf_amp_list - a vector of RF amplitudes at each
pulse slice, rad/s
parameters.rf_dur_list - a vector of pulse slice durations,
in seconds
parameters.rf_phi - pulse phase at time zero
parameters.max_rank - maximum rank in the Fokker-Planck
pulse operator (2 is usually enough)
Outputs
fid - k-space signal, run an FT to get the image
Examples
See slice_select_1d_shaped.m and slice_select_1d_square.m files in examples/imaging directory.
