Influence of geometric and material properties on artifacts generated by interventional MRI devices: Relevance to PRF‐shift thermometry

Purpose: Magnetic resonance imaging (MRI) is capable of providing valuable real‐time feedback during medical procedures, partly due to the excellent soft‐tissue contrast available. Several technical hurdles still exist to seamless integration of medical devices with MRI due to incompatibility of mos...
