epi_2d.m

2D echo planar imaging pulse sequence.

Syntax

    mri=epi_2d(spin_system,parameters,H,R,K,G,F)

Parameters

  parameters.pe_grad_dur  - the duration of the phase encoding
                            gradient (X), seconds

  parameters.ro_grad_dur  - the duration of the readout 
                            gradient (Y), seconds

  parameters.image_size   - number of points in each dimension
                            of the resulting image

  parameters.diff_g_amp   - [optional] a vector of diffusion 
                            gradient amplitudes in X,Y (T/m)

  parameters.diff_g_dur   - [optional] the duration of the 
                            diffusion gradient, seconds

Outputs

 mri - MRI image with square sinebell apodisation.

Notes

This sequence must be called from the imaging.m context, which would provide H,R,K,G, and F.
