Electromagnetic Simulation of Signal Distribution of Various RF Endoluminal Loop Geometries with Coil Orientation: Towards a Reconfigurable Design

Figure 6

The phantom used for simulation of different loaded loop coils. It consists of a cylindrical vessel with a through-hole with dimensions of 9.2 mm inner and 45 mm outer diameters, and 50 mm length, and is filled with a solution of 1.25 g NiSO₄x 6H₂O + 5g NaCl per liter of distilled water mimicking tissue losses (0.67 S/m conductivity, 94.73 relative permittivity/dielectric constant, and 1120 kg/m³ mass density). It was meshed with a 2 mm local mesh size.
