Development of AC Magnetic Susceptibility Imaging for Biomedical Applications

Kolloquium der Abteilung 8

Magnetic susceptibility imaging using AC magnetic fields and room temperature pickup coils has several potential applications in medicine. In this talk, we will introduce the method of AC magnetic susceptibility imaging and show the results of early prototypes that demonstrate the sensitivity of the approach to magnetic nanoparticles. Preliminary evidence of sensitivity to biological tissues that contain iron will be shown with a signal detection instrument.  Biomedical applications of AC magnetic susceptibility imaging will be discussed in the fields of cancer research, iron deficiency diagnostics and neuroengineering.
