Voxel selection diagnostics function for 2D PRESS sequences that returns the sample excitation profile; it must be called from the imaging.m context, which provides H,R,K,G, and F.
Syntax
phan=press_voxel_2d(spin_system,parameters,H,R,K,G,F)
Parameters
parameters.ss_grad_amp - the two amplitudes of slice selection
gradient, T/m
parameters.rf_frq_list - cell array of two vectors of RF frequ-
encies at each pulse slice, Hz
parameters.rf_amp_list - cell array of two vectors of RF
amplitudes at each pulse slice, rad/s
parameters.rf_dur_list - cell array of two vectors of pulse
slice durations, in seconds
parameters.rf_phi - cell array of two pulse phases at
time zero
parameters.max_rank - cell array of two maximum rank in the
Fokker-Planck pulse operator (2 is
usually enough)
Outputs
phan - the excitation profile imprinted into a 2D phantom.
Examples
See press_2d_example.m file in examples/imaging directory.
