Electromagnetic Simulation of Signal Distribution of Various RF Endoluminal Loop Geometries with Coil Orientation: Towards a Reconfigurable Design
Figure 7
Different steps from the coil design to the analysis of results. (a) Full-wave electromagnetic simulation with FEKO software to get the magnetic field H1. (b) Application of the coil-orientation effect about x-axis on (which is proportional to the SNR) distribution by using Matlab software (3D transformation based on rotation matrices). (c) Analysis of the results corresponding to the chosen criteria: coefficient of variation between 5 mm and 15 mm from the center of the coil (targeted colon wall imaging area).
