Slice select 1d.m

Slice selection diagnostics function.

Syntax

    fid=slice_select_1d(spin_system,parameters,H,R,K,G,F)

Description

Executes a shaped pulse on the user-supplied 1D phantom and records a 1D image. 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.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
