Summary

Passive shimming with austenitic stainless steel patches significantly reduces transcranial magnetic stimulation (TMS) coil artifacts in functional magnetic resonance imaging (fMRI) by 80%. This technique minimizes magnetic field distortions, improving image quality for combined TMS-fMRI studies.

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
