Active Electromagnetic Interference Suppression for MRI and Proton Resonance Frequency Shift Thermometry During MRI‐Guided Microwave Ablation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a software‐based active electromagnetic interference (EMI) suppression (AES) framework on whole‐body multi‐channel MRI systems for reliable MRI and MR thermometry during MRI‐guided microwave ablation (MWA). Methods In addition to primary imaging coils, an unloaded standard body array coil was positioned outside the imaging ...
