Abstract/Summary This paper presents a stabilized Bi-conjugate gradient algorithm that can significantly improve the performance of the impedance method, which has been widely applied to model low-frequency field induction phenomena in voxel phantoms. The improved quasi-static impedance method offers remarkable computational advantages in terms of convergence performance and memory consumption over the conventional, stationary iterative method-based algorithm. The scheme has been validated against other numerical/analytical solutions on a lossy, multilayered sphere phantom with an ideal coil loop excitation. To further demonstrate the computational performance and application capability of the developed algorithm, the induced fields inside a whole body human phantom responding to hyperthermia device was evaluated. The simulation results show the numerical accuracy and superior performance of the method.
