Tutorial: MRI Loop Coil


 * Download the latest matlab file using gitweb: MRI_Loop_Coil.m



Requirements

 * openEMS v0.0.31 or later
 * Matlab R2011a or later for converting the body model once! (Octave currently is not supported, see Alternatives below)
 * The "Virtual Family Model" : (see Alternatives below)

This tutorial covers

 * setup of a MRI Loop Coil for 7T
 * Converting and including a Virtual Family Body Model
 * adding two SAR dump box planes
 * calculate the S-Parameter and input-impedance of the loop coil
 * calculate and plot $$B_1^+$$ and $$B_1^-$$
 * calculate and plot the SAR distribution

Alternatives
If you don't have access to Matlab (to convert the body model once) or have no access to the virtual family body models, you may want to replace the discrete material with a simple phantom model: CSX = AddMaterial(CSX, 'phantom_head'); CSX = SetMaterialProperty( CSX,'phantom_head', 'Epsilon', 60, 'Kappa', 0.7, 'Density', 1040); CSX = AddSphere(CSX, 'phantom_head', 0, [0 0 0], 110,'Transform',{'Scale',[1 0.8 1]} );
