Simultaneous use of multiple applicators is desirable in MRgMWA when treating large tumors and its feasibility is investigated in phantom experiments to evaluate the impact of MW system on MR image quality and in ex-vivo experiments with porcine tissue to compare MWA procedures with one and two applicators. Relative SNR was dropped from 88.1% with one applicator activated to 54.6% with both activated, yet temperature and tissue damage maps with acceptable image quality were obtained. Simultaneous use of two MW applicators could significantly increase the treatment efficiency with a larger ablation zone when both applicators are properly selected and configured.
