Monopole coil has a thin and flexible structure provides high-resolution MR images from the internal vessels such as aorta and coronary arteries. However, its SNR homogeneity decreases at higher Tesla MRI systems, leading to increasing the image artifact caused by the wall movement which is not fully compensated using the post processing algorithms. In this study, we introduced a monopole coil with tree parasitic elements and compared its ISNR (Intrinsic SNR) magnitude and distribution homogeneity to a conventional monopole coil with one parasitic element for MRI 1.5 T at 64MHz . We optimized the coil geometry using a fast genetic algorithm written in MATLAB and performed the simulation of the ISNR indices by Involving HFSS and MATLAB inside a saline phantom.
