Performance of a petal resonator surface (PERES) coil via equivalent circuit simulation

MRI coil parameters can be estimated via simulation using an equivalent RLC circuit to investigate coil performance. The Spice Opussimulator was used to simulate the loss return coefficients of a circular-shaped coil and a petal resonator surface (PERES) coil via equivalent(RLC) circuit. Simulated c...
