Quasistatic Solutions versus Full-Wave Solutions of Single-Channel Circular RF Receive Coils on Phantoms of Varying Conductivities at 3 Tesla

(a) 1D relative SNR (rSNR) plots (left) and 1D rSNR ratio plots (right) of quasistatic (Q), full-wave (FW), and measurement (M) data collected on a 0.3 S/m phantom with data points taken along each coil element’s axis. The coils were separated from the solution by a 6 mm thick lossy polycarbonate former, except that no former was used in the quasistatic simulations. Each legend corresponds to its respective column. (b) 1D relative SNR plots (left) and 1D rSNR ratio plots (right) of quasistatic (Q), full-wave (FW), and measurement (M) data collected on a 0.6 S/m phantom with data points taken along each coil element’s axis. The coils were separated from the solution by a 6 mm thick lossy polycarbonate former, except that no former was used in the quasistatic simulations. Each legend corresponds to its respective column. (c) 1D relative SNR plots (left) and 1D rSNR ratio plots (right) of quasistatic (Q), full-wave (FW), and measurement (M) data collected on a 0.9 S/m phantom with data points taken along each coil element’s axis. The coils were separated from the solution by a 6 mm thick lossy polycarbonate former, except that no former was used in the quasistatic simulations. Each legend corresponds to its respective column.
