Magnetic resonance imaging of deep brain stimulation (DBS) patients remains a safety concern at higher magnetic fields strengths. Phantoms play an important role in validating and estimating patient safety conditions. However, conventional phantoms are typically simple homogeneous structures that limit the ability to replicate DBS surgical implant procedures. In this work, a new phantom structure is proposed with more human-like realism and compartments to enable improved replication of DBS device placement geometries. Preliminary radiofrequency heating results demonstrate significant differences in temperature elevations when the phantom is assembled in a heterogeneous and homogeneous configuration.
