1D PRESS (voxel-selective NMR) pulse sequence that performs voxel-selective excitation and records an NMR spectrum; it must be called from the imaging.m context, which provides H,R,K,G, and F.
Syntax
fid=press_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 - free induction decay of the NMR spectrum
Examples
See press_example_1d.m file in examples/imaging directory.
