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.
