We present a method for evaluation and visualization of the array RF coil performance in MRI (Magnetic Resonance Imaging). The parameters to evaluate are the spatial sensitivity distribution, SNR, g-factor, and the noise correlation matrix of the array RF coil. For easy and efficient evaluation of the coil performance, we visualize the sensitivity and SNR maps of each coil element on the relative axial-, sagittal-, and coronal-planes which are defined with respect to the plane of the corresponding coil element. We made the 3D model of a helmet-style array coil using a commercial 3D modeling software after we had measured the 3D geometry of the coil using a 3D scanner. With the 3D model, we simulated the coil performance parameter maps using a FDTD solver. Then, we displayed the simulated parameter maps and experimentally obtained parameter maps in parallel on the three orthogonal planes defined relative to the each coil plane. We think the proposed method can be used for quality control of array RF coils.
