Commercial hyperthermia systems: (A) A clinical MFH 300F hyperthermia system ¹²² consists of a resonating circuit at a ferrite yoke that generate an oscillating field of 100 kHz between the pole shoes above and beneath the treatment aperture. The setup can be adjusted to limit the exposure of oscillating magnetic field exposure on the patient and (B) its corresponding field homogeneity in the transverse direction ¹²². The patient is slid through the aperture and the aperture distance controls the effective area of exposure and the field can be adjusted by adjusting the current to the coils.

The particles in zone *A heat up the most, with steep fall off at zones *B and *C. (Reproduced with permission from ¹, Copyright 2018 American Chemical Society).
