Voxel selection diagnostics function for 2D PRESS sequences.

Returns the sample excitation profile. This sequence must be called from the imaging.m context, which would provide 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
